* The sort handler was expecting to deal with a 2D array, so we always
dropped into the single column first sort condition.
* See thread 20811 for more information.
- The stateDuration option has been updated to provide the ability to
indicate if sessionStorage should be used rather than localStorage
(set value to -1).
- Settings stateDuration to 0 also indicates that the duration is
infinity.
- Parts of the state saving have been optimised for code size, so this
commit actually reduces the min size by 32 bytes despite the new
abilities.
- See thread 19572 for discussion on this
- The column index selector was broken by a previous commit (d9f416232).
- Fix also an error in the column selector whereby a result was being
tested against itself
- If you provided your own <select> list for the lenght language option,
DataTables would still append its own and ignore your custom one
- See thread 20548
- Feedback from James Craig on improving the accessiblity of DataTables.
Since the `role=grid` option is added to the DataTables table, we
should also add `role=row` to the rows in the table so the browsers
can see them correctly. As James notes, it is debatable if this is
needed or not but it is required in current Chrome and Webkit.
- Webkit do now allow roles to be optional in the nighties - see:
https://bugs.webkit.org/show_bug.cgi?id=131819 . Once Apple deploy
this in a Safari update, and Chrome also deploy support, I think this
should be removed from DataTables core, since it will no longer be
needed in the latest browsers, and manipulating the DOM can hit
performance a bit.
- It is useful to be able to filter row indexes by a condition and then
operate on the resulting array of indexes, but before the selector
would only itterate over real arrays. So if you passed is an API
instance with the result set being the indexes to delete, it wouldn't
work!
- Fix is to loop over anything which has a `length` property
- Thread 20572
- Remove the aria-relevant from the info text to use the default,
otherwise it was reading information that isn't very useful
- Change info text role to `status`
- Remove `role=row` from header - this is experimental and might change.
Might need it on this row and all rows in the table
- Based on feedback from James Craig (thanks!)
- If you were to click the 'previous' button when on the first page, the
table would redraw - that's the easiest manifestation of this bug to
see. There is no need to redraw the table when the paging hasn't
changed, so don't.
- This fixes DataTables/DataTables #304
- Because DataTables is destroying and creating elements for the paging
control, focus is lost when navigating via keyboard. This is a real
pain when trying to operate DataTables that way! Fix is to refocus on
the new element.
- If you used client-side processing ajax, the parameter passed into
_fnBuildAjax is an array, needed for the old 1.9 compatiblity, but the
ajax wasn't transforming this into a data object and then sending it
to the server. The fix is to check if the data passed in is an array
or not - if so, transform it to an object
- If you use multiple column definations such that a columns' sorting
options are initially disabled and then enabled, the sorting classes
for the header were not being applied correctly.
- The fix is to always assign classes based on the most up-to-date
information for the column.
- This fixes DataTables/DataTables #303
- The resolution of unknown sorting types was being done after the
sorting structure array of objects was being calculated. As such, a
string sort was always being done in the first instance!
- This fixes thread 20433
- In a fenced code block, need to encode the HTML elements. However, the
HTML was being detected and saved first. Run the fencer first.
- Type links updated
- When invalidating a DOM row, DataTables wasn't taking into account the
fact that the columns in the row might be hidden. This means that the
array of data read is shortened by the number of hidden columns, and
thus the data is corrupted.
- Fix is to read from the known cells if the row already exists
- Issue here was that when doing the camelCase to hungarian conversion
on objects, the user object was copying over the hungarian default.
This meant that parameters were lost and things broke! The fix is to
decend into the object
- See thread 20233 for the original report
- DataTables' smart filtering now has the ability to search for an exact
string, in the given order, over multiple words. This is done by
providing the exact match search string in quotes - for example:
Angela "Cheif Exec" London
Will match three terms - `Angela`, `Cheif Exec` and `London`. Those
three terms will be matched in any order.
- This matches the search behaviour that we all know and love in Google!
- It can be disabled along with the rest of DataTables' smart filtering
using the `smart` option.
- This enhancement comes courtesy of Barry Keepence. Original forum
thread: http://datatables.net/forums/discussion/16250/. Thanks!
- See thread 20075 for the original report
- Basically the issue here was that the object being used for the API
extension on objects (e.g. `table.ajax` is an object) the object was
not unique to each API instance, so it was being shared between
instances and as a result, whatever instance was created last, would
win!
- Fix is to use a new object each time.
- DataTables uses the `DT` namespace for events internally and will
remove them automatically on destroy, but `dt` is used for public
events. As such, the public events used internally should use `.dt.DT`
to ensure that the listener works as expected, but also so that the
destroy call will remove these listeners
- This is to preserve user added listeners on destroy. If they want to
remove their listeners to prevent memory leaks, then they should do
so. But DataTables won't do it for them, as actually, you might want
to keep your event listeners!
- fnServerData's second parameter should be an array of objects with
name/value pairs. It was being passed through as the more modern
object, but fnServerData is only present for compatiblity with 1.9 and
should the original format should be retained. This is done with a
simple map function
found
- The old fnGetData method would return null, rather than undefined for
some reason if a given row was not found in the DataTable. The new
wrapper api for the legacy interface should do the same.
- Previously if you cancelled an Ajax request, or the browser did (for
example following a link) the error handler would be entered and show
an alert. This just ensures that the request is complete before
showing an error
- Previously when using columns.render as an object, you had to supply
an `_` option which was the fallback. However, I've now made it so
that if there is no `_` option it will just use the raw data from
`columns.data`
- I've come accross a lot of cases recently where numbers need to be
formatted for display, so I wanted to introduce rendering helpers for
DataTables to make this easier. Only one helper introduced here -
`$.fn.dataTable.render.number()` which will return an object that can
be used by `columns.render` to format "raw" numbers.
- The child row feature of DataTables should be able to take a `tr`
element and add that directly as a child. That wasn't working due to a
logic error before.
would be removed from the array of data passed through to the custom
filtering functions. This would cause indexes to misalign.
- The fix is to simply pass in the data filter array that has already
been computed, as that is 1:1 for the display. Also added the raw data
source object for the row for completeness and a bit of a code tidy
up.
- This will cause a bit of an indexing issue, if you have bVisible:false
set, but this is certainly a bug that had to be fixed - it just didn't
make sense as it was, and went against the documentation!
- See thread 19593 for more information
newly created elements
- The fix i've put in is basically the same as what DataTables 1.9-
used. I had tried to opitmise it a little, but it wasn't working for
newly created cells. I still think this can be optimised, but for the
moment, this is at least allows it to work.
and result set for the plural methods.
Fix: Row details events were itterating over non-DataTables rows
creating a Javascript error
Fix: Example - Server-side processing row details example updated to be
able to restore the details row on a redraw.
Update: Documentation - Most examples which used `flatten()` are more
correct to use the new `eq()` method, so they have been updated.
- This set of changes is based on the discussion in thread 19377. While
working on the fix, I realised that the use of flatten() is too broad,
so the new `eq()` function is introduced. It is similar to the jQuery
eq() method in that it reduces the instance to just the selected
index, although in DataTables this is both the context and the result
set. Its a small addition, but I think it will provide to be very
useful
DataTables which character is used as a decimal place in the table's
data, so that number which are formatted using characters other than a
dot as the decimal place can be correctly detected and sorted.
- A large part of the world uses the comma as a decimal place, so it
makes sense to have this option built-in directly to DataTables,
rather than needing to use plu-in sorting types as before:
http://en.wikipedia.org/wiki/Decimal_mark
- However, the decimal place character cannot be detected automatically
since there are far to many ambiguities. As such, a new
`language.decimal` option is defined which is passed through to the
type detection functions. The type detection functions can then use
that character to alter their detection functions to transform numbers
into the dot formatted equivilent for parsing in Javascript.
- The numeric sorting methods have been bundled together in the function
`_addNumericSort` which is called when a character is given for the
decimal mark, adding the sorting functions required specifically for
that mark. This means that any character at all can be added, while
keeping the table's sort performance as it was.
- Code size in increased a little for this new feature, but a lot of
work has been done to keep it to a minimum (while still optimising for
the most common use case of a dot decimal place), and this is a good
feature to have in DataTables' core code.
- All required documentation added and updated.
- Special thanks to Tobias Bäthge for suggesting and sponsoring this
feature.
- This is caused due to different content in the displayed header and
the size forcing header in the body scrolling table. The browsers can
lay the two tables out differently even although the widths applied
are identical, due to the different content.
- The fix is to keep the content in the scroll body header, but hide it
by wrapping in a div which has height 0 and overflow hidden
- See thread 19311 for more information
server-side processing
- A popular plug-in for DataTables is the `fnSetFilteringDelay` plug-in,
which provides a bit of a buffer when typing into the filter input so
you don't make an Ajax request for every key stroke - i.e. don't DDoS
your own server!
- Since we have _fnThrottle built in now for the scrolling, we can also
use it to provide this buffering functionality for server-side
processing filtering in the core. A couple of small changes for
_fnThrottle were required to get the callback context correct and ot
call it not immediately, but only after the delay
footer
Update: Update CSS to display the table border properly when there is no
footer when scrolling
Dev: Update the _fnAddOptionsHtml function to be smaller in code size.
Identical functionality, just smaller code
fact that the table width attribute has been removed, but was being
applied to the table anyway, as 0px - causing the table to be as narrow
as possible. On the plus size, the columns kept their alignment with
such a misconfiguration! However, now the `width` option for columns is
correctly applied in x-scrolling tables.
don't need to look it up with inArray. Also the header renderer does not
pass in the column index now (the column.idx property can be used). This
is to allow operations such as ColReorder to reorder teh columns and
still have the renderers update correctly
- Column width is always a particularly difficult one to get quite
right. In this case, the fix is to have DataTables read column width
information from the `width` or `style` attributes of a column header
cell, if that information is present. If it is, it is treated as
sWidth is (although user supplied sWidth can override). That is it say
that it will be applied to the column width calculation table.
- The remaining gap is if a developer assigns a width using css classes.
We can't get that information, so we fall into the old problem.
- This change comes about from the discussion in
http://datatables.net/forums/discussion/19089 and the fiddle here:
http://jsfiddle.net/EysLd/1/
- What is happening in the test case is that the calculation table is
being created, but it is then stripped of widths due to this commit:
https://github.com/DataTables/DataTables/commit/6a9e324 . That was to
allow DataTables column headers to have their applied size removed, so
a new size could be calculated. Only sWidth would override that - now
the width and style attributes will as well
- IE8- requires that Function.prototype.apply be used with an array or
arguments object as the second parameter - it being "array-like" isn't
good enough.
- This fixes DataTables/DataTables #262
plug-ins
- A lot of plug-ins use _fnCalculateEnd and although all that is needed
in the upgrade is to remove it, since the value is calculated
automatically now, it will likely cause confusion and hassle. So I've
added this stub to prevent those errors.
- Chrome (V8) will incorrectly detect '$245.12' and similar as dates,
since V8 will strip unknown characters from a string given to
Date.parse and then attempt to parse the rest of the string - in the
example above: Dec, 245:
https://code.google.com/p/v8/source/browse/trunk/src/dateparser-inl.h#72
- The fix implemented to to check for a leading a-zA-Z, number or +-.
Although this isn't a perfect match for what Chrome does, it, I think,
a good enough effort to chatch nearly all particular use cases.
- Additionaly, V8 will try to parse a single number passed into
Date.parse - 1-12 are months, 32+ are years. As such, the numeric type
detection much be a highter priority than the date detection, since
Chrome might incorrectly use a column as a date. It would sort
correctly, but it isn't "correct".
- The take away from this is that Date.parse cannot be used for date
format validation on its own...
1D arrays.
- The method implemented isn't actually 100% perfect - if you mix arrays
and scalars, then the behaviour is undefined. But that shouldn't
happen in DataTables. Will look into it further, though
- This is actually a little more complex than it might first appear
since any classes which have been added by DT_RowClass need to be
removed. We can't just bindly remove all classes, so we need to track
that classes have been added in a private variable.
- It appears that ti is impossible to know in CSS if a table doesn't
have a tfoot element reliably and cross browser, so I've added a class
which is added to the table automatically if the table has no footer
or the fotoer is empty to complete the styling of the table.
- Fixed error when there are no cells in an empty TR row in the footer.
- With the change to camelCase, it is easier to extend the usageof
optiosn now, and in this case I've allowed the `orderFixed` (formally
`aaSortingFixed` parameter to be passed in as an object as well as an
array. As an object the `pre` and `post` parameters are used to
specify prefix and / or postfix ordering. Useful for gouping.
- The _pluck() function that was being used to get the tr elements
didn't remove nulls, while jQuery doesn't like removing a class from!
- Thanks to `RagingTroll` in the forums for spotting this:
http://datatables.net/forums/discussion/18651
the property being expanded is an object or not. If not, then set it to
be an empty object which will be extended. Only really effected the
`ajax` property
Based on the discussion in the forms (
http://datatables.net/forums/discussion/18456 ) the fix from 8935b8a
wasn't good enough. What was happening was that the _save_data function
was doing a deep copy of all arrays (minus the data array) so the
default sort was stil applied.
The fix is to reinstate the _fnExtend function which does a jQuery like
deep extend on objects and a shallow extend on arrays. That is extended
slightly to allow array references to be broken on initialisation, to
resolve the issue 8935b8a attempted to (sorting array would be used for
two tables for example), by an optional parameter. This should resolve
the issue correctly this time!
- This fixes DataTables/DataTables issue #241.
- Most of the properties attached are objects, so we want the references
to them, rather than a copy, so a simple assignment is all that is
needed. Strings etc will continue to work as well.
syntax paraneter names
- Data added using fnServerParams with array syntax had different
behaviour in 1.10 from 1.9. In 1.9 jQuery would create an array for
us, but in 1.10 before we create an object first, we need to create
that array ourselves. So the following code had different behaviour:
"sAjaxSource": "data/arrays.txt",
"fnServerParams": function ( d ) {
d.push(
{name: 'somekey[]', value: 'somevalue1'},
{name: 'somekey[]', value: 'somevalue2'}
);
}
In 1.10 it would have sent `somekey[] = somevalue2` but 1.9 would have
sent both as part of an array.
To maintain full compatiblity with 1.9 we need to convert this syntax to
an array - this commit does that.
I was concerned about using parameters in the brackets, but jQuery only
searches for `[]` when performing this conversion. We could use $.param
and then decode the created query string, which would be absolutely 100%
comaptible, but would involve additional code and I think this method
provides that 100% compatiblity from reading the jQuery code), and its
shorter.
- This is the CSS version of the cellspacing attribute on the table in HTML. It will work in all browsers except IE6/7. IE8+ and the others are all fine. So for the moment most of my examples will continue carrying the cellspacing attribute, but this is useful to have in the core css
- The ability to use negative numbers as a column selector for the
column data index was added recently, but that didn't include the
ability to work with negative numbers with the :visible pesudo
selector. This commit adds that ability so you can do:
`table.column("-1:visible")` to always get the right most visible
column
with :name postfix.
- Previously you could use a jQuery selector for columns by using the
:jq postfix, and names were matched otherwise. This is reversed now
for consistency with the rows and cells selectors which treat strings
as jQuery selectors without the :jq postfix.
returned undefined, null etc.
- The base issue was in the instanceof check which has a priority error,
it was:
! obj instanceof _Api
which is the same as:
(! obj) instanceof _Api
which is rubbish.
We want:
! (obj instanceof _Api)
but there is of course a wrapper function, so that needs ot be taken
into account as well. The new logic does just that.
- Because of the manipulation of the initalisation object initialisation
of multiple tables with a single jQuery call (i.e.
`$('.dataTable').dataTable();`) was broken since the second table
would see the modified init object. Need to take a coopy of the object
before entering that state.
- This could probably do with a bit of a clean up sometime...
- The displayLength option is poorly named, particularly with the new
API refering to it as the page length (page.len()) so, using the new
translation option to allow backwards compatiblity while using new
parameter names, I've updated this parameter's name and its
documentation.
- Renaming in keeping with the new terminology
- Updating example which uses it (main documentation still to be
written)
- Backwards compatible with a bit of logic to check if the old version
is being passed in
- Decided that it would be better to provide the new API by having
plug-ins extend it directly, rather than providing their own API.
Using the plugin() method it was possible to get a plug-in insta,ce
for example TableTools, but the way it should work is that TableTools
would provide a tabletools() API method, registering it as an
extension to the DataTables API objects. Further more, TableTools
should provide methods such as row().select() etc, extending the
current API rather than doing its own thing which the plugin() methods
prompted.
- No backwards compatiblity issues here as the plugin() code hasn't
shipped as a release.
- I added a static DataTable.on() method previously in the 1.10
development for a single event called `construct` which would tell us
when a table was constructed. But I've realise that since the events
that DataTables' triggers bubble up through the document, that effect
can already be achieved:
- Use:
- $(document).on( 'init.dt', function ( e, settings ) { } );
- Rather than:
- $.fn.dataTable.on( 'construct', function ( settings ) { } );
- No backwards compatiblity issues as the DataTable.on code was never
shipped, its dev code only
- Previously DataTables would only show an error message if there was a
JSON parsing error. However, if there was any other kind of error,
such as a 404, it would just silently swallow the error. THink its
best to show an error and a tech note.
- This is a breaking backwards incompatible change - please be aware of
this!
- DataTables fires custom events such as `draw` etc, but these events
were in no way identifyable as eminating from DataTables rather than
some other component, which can cause confusion and difficulty
resolving bugs.
- As such, all DataTables events are now fired with the `dt` namespace -
this means if you are currently using events, you must update your
code to also use the .dt namespace. If you are already using
namespaces, that's great, you can continue to do so as jQuery allows
multiple namespaces, but you must still use the .dt namespace.
- This is a breaking change because the old behaviour was incorrect -
i.e. this was a bug to be fixed, hence why we haven't gone through a
deprecation cycle. The old events weren't well documented (only in the
JSDoc generated docs and a few of my forum posts), whereas in 1.10
they will form a key part of the documentation. As such, now is the
time to get this right. This will be documented clearly in the upgrade
notes.
- Discussion on this topic here:
https://github.com/DataTables/DataTables/issues/245
- columns().cache() should check for the parameter 'search' for naming
consistency
- Plural error on column().nodes()
- Change column.index() fromIndex/toIndex to fromData/toData - its an
index be it data or visible, so the old method was meaningless
- The columns() methods have header() and footer() children to get the
header and footer cells for the columns. For naming consistency the
table() methods should be named likewise
- to$ - Convert the result set to a jQuery object. Compliment to the
toArray method. This is mainly useful when working with the node() and
nodes() methods.
- toJQuery - Alias of to$
- join - Array join method
- With the new API the filter() and sort() methods already have meaning
(the array methods built into Javascript) so the methods for filtering
and sorting in the API are called search() and order() respectively.
However, the intialisation parameters and events in DataTables use a
mix of filter, search, sort and order in their terminology so this
commit harmonises on just search and order, updating where
appropriate.
- There are a number of incompatible changes if you are already using
the new options in 1.10, but no incompatible changes to the latest
release (1.9.4). 1.10 changes:
- Server-side processing, the new parameters sent have been updated
to refelect the new terminology
- The Ext object likewise has been updated
- Default with the old options and padding int he old options will still
work as before, compatiblity functions have been added to provide
mapping. If both are provided the new parameter value will take
president.
- The change is primarily around `sort` since that was reasonably
consistent in its terminology for the initlaisation parameters before.
column index referencing of the cells.
- Previously a colspan in a footer cell would cause index misalignment -
for example if you had a table of 6 columns with two in the footer
(one colspan=5) the fotoer cells would be assigned to the first two
columns in the table, breaking column index order. Now a cell can be
used over multiple columns. This allows column().footer() to always
reflect the cell that belongs to that column (possibly sharing it with
other columns).
- Note that the footer will only use cells from the first row in the
footer. If there is more than one row, use table().foot() to access
the TFoot element and then manipulate it as needed.
- The fix here is to set the box sizing for the table and its cells to
be content-box sizing to allow the column width calculations to occur
correctly - 17932
display
- In the examples we want to show the following information to help
developers to get to grips with DataTables more readily:
- Init javascript code
- HTML used for the table
- Additional CSS used
- Ajax loaded data
- List of the libraries files loaded in the example
- All but the last point is complete, a bit of styling and information
text.
option
- By passing in no parameters to the search API methods we can get the
current search value - for example:
$('#example').DataTable().search();
- This is to round of the API as the order() method already has a get
option as to the paging information
- Variables and functions which are to be private in DataTables, but
available across all files have a single leading underscore.
- Variables and functions which are to be private in a single file have
two underscores (but no self executing function to restrict scope as
that will just take extra space).
- Externally exposed functions and JSHint globals list updated
- When working with plug-ins such as TableTools, there is no clearly
defined way at the moment to get at the plug-in instance, with each
doing it its own way (TableTools as a static function, while Scroller
attaches itself to the settings object and KeyTable is its own
intialiser, amoung others...) so I'm introducing these methods to
unify this.
- plugin() is used by DataTables users to get their plugin instance, for
example `table.plugin('tabletools')` would get the TableTools
instance allowing full access to its API.
- plugin.register() and plugin.deregister() are called by the plug-ins
when they attach themselves to a DataTable. The 'extras' will all need
to be updated to use this new method.
- Some plug-ins would benefit from be able to automatically initialise
when a DataTables is constructed, to this end, a construct for static
events is added here, with the static function $.fn.dataTable.on()
listening for events. Currently only the `construct` method is
available, although others could potentially be added in future if
they are useful. As such, the code driving it is intentionally simple
for this cas,e but the API abstract enough to allow future expansion.
- There is no `off()` method, as I'm not sure it would be that useful.
Could be added in future if needed!
- The server-side processing parameters used by DataTables 1.9 are very
ugly, and rather arkward to work with, so in keeping with the
camcelCase approach of 1.10 and its general monderisation, when using
the `ajax` option to set the ajax url for data, DataTables server-side
processing will now use a much more modern method of telling the
server what data is required - specifically using arrays and objects
in neatly formatted data.
- The old 1.9 method is invoked if sAjaxSource is used to set the ajax
url, or if $.fn.dataTable.ext.legacy.ajax is set to true. As such,
this change should be fully backwards compatible since `ajax` is a new
option in 1.10.
- This new ability adds 334 bytes to the min file, primarily, because
the old method is retained (using just the new method would actually
reduce the size slightly).
- The _fnCalculateColumnWidths is probably the oldest function in
DataTables which has mostly reamined as it was 5 years ago! However,
its time to trim it down a bit and optimise now. This rewrite has all
the same actions, but results in a minified file which is about 700
bytes smaller than before.
- The bAutoCss parameter is not one that I've ever actually seen used,
so I've dropped it out here to reduce complexity. It was only useful
for making the scrollbars always visible on the table, which can just
as easily be done with `div.dataTables_scrollBody { overflow: scroll
!important }` since that will take a heigher priority that the
DataTables appled style.
- The moster _fnFeatureHtmlTable and _fnScrollDraw functions have been
refactors, saving around 1.5K in size (in the minified file)
- The infinite scrolling feature of DataTables is inadequate as a
solution for the problem it is trying to solve as it introduces a
number of compatiblity issues with the rest of the API parimarily
due to the fact that it "tricks" the rest of DataTables into drawing
just a small proportion of the table, leaving the elements which are
currently in place. This means that DataTables doesn't realise that
the table has additional rows at the top of the table, thus breaking
numerous interactions with the API and confusing developers. As such,
its a poor feature that is just taking up space and could be done much
better externally.
- I will write an infinite loading feature for DataTables in future for
users that do what to use this ability - there is nothing stopping a
simple scroll event being attached to the scrolling element and
calling the rows.add() function. This is exactly what the new plug-in
will do.
- Scroller is a much better solution for defined length tables.
- In keeping with the camelCase name changes for DataTables 1.10, the
default Ajax data source object property name has been updated from
`aaData` to just `data`. Note that this is a fulyl backwards
compatible change - if aaData is present in the data, it will be used.
<input> controls used by DataTables for length change and filtering
respectively.
- Bootstrap 3 requires a styling class be set directly on the element,
so in order to correctly support Bootstrap 3, which we want to do, we
need to have the ability to set these classes. This commit adds that
ability
- Because of the decoupling of the filtering and sorting, the filtering
was missing that the indexes of the displayed data will have changed
after a sort. So need to do a full filter when just sorted
styling
- Note that I've included the bootstrap and Foundation integration files
in the resources folder. In future these files will be on the CDN, but
that isn't up and running yet...
- scrollX was often the source of frustration when setting it to
anything other than "100%", which is was in the demos and
documentation but it makes it easy to see that you could set it to be
50% or anything else. That usually broke the developer's layout. So
now you can just use scrollX: true, to enable horizontal scrolling.
The demos have been updated for this.
- A numebr of support requests are about why the layout immediately
after a DataTable looks wrong, and its usually because of the floats
used by info / paging, so we self clear the wrapper around the
DataTable controls
- Updating the build process to introduce the example builder to convert
the XML example files into HTML files. This process is performed for a
number of reasons:
- Much more maintainable - links automatically updated
- Add / remove examples easier
- Modify page styling easier
- Examples can be directly integrated into web-site since they are
transformed by template
- Common data sharing
- Note that the work on the new example build process is not complete in
this commit, there are still a few things to do! css, media paths and
completing the templates.
- Rather than creating a new JSON object from the XHR, use the one that
was returned by the server. This is useful if you manipulate the data
since you want to just keep using the same object.
- The HTML5 attribute detection for sorting, filtering etc was breaking
if you didn't provide a filtering _and_ sorting attributes since they
created an undefined get data function, which causes DataTables to
complain. Fix is to just check for a null value.
- IE10 has a little `x` to clear text boxes which fires the `input`
event, so we need to monitor for that in the filtering input.
- While I'm here, I've also added support for the paste and cut events
to change the filtering when they fire. Via keyboard the fire on
keyup, but not if you use the mouse. They do now.
- Not that it us possible to have multiple events fire (keyup + paste
for example). The logic of checking for a change of input counters
this.
- Thhis fixes DataTables/DataTables issue #227.
- Based on thread 17024 - if you have a large table with a lot of
elements in the tbody, the find('*') selector was of course selecting
them all. That results in poor performance. DataTables doesn't add any
events to the children in the tbody, so we can filter out those
elemetns and keep the element list ot a sensible size.
- Based on the discussion in forum thread 16961 and the results from
http://jsperf.com/html-decode I've updated how the HTML decode for
filtering is done to bypass jQuery and use DOM methods directly. It is
more code but it is also much faster.
- Based on feedback from Rich Caloggero in forum thread 13421 the ARIA
live region DataTables was adding to the TBODY element of the table
have been moved to the table information element, so screen readers
don't go mad announcing the new informaiton in the table on every
change, but rather just read the summary.
- The built in filtering formatters and type detection need to be able
to handle just about any data being passed into them. They were
tripping up with null data being passed in before.
- Based on the discussion in forum thread 16938 DataTables now has the
ability to use _PAGE_ and _PAGES_ in addition to the exisiting
_START_, _END_, _MAX_ and _TOTAL_ options in the information language
strings. This allows the developer to show paging information rather
than record based information in the information element.
Based on DataTables/DataTables/issues/214 this commit uses the optional id parameter for the AMD define function to give DataTables a 'name' for easy referencing.
- DataTables tables previously did not automatically adjust their sizing
when the window width was changed, which let to a lot of additional
calls to fnAdjustColumnSizing in peoples code (and support questions
in the forums). This commit add adjustment to the sizing automatically
for tables width have width="100%" as an attribute (we can't use CSS
since we can't know if it is relative or absolute sizing) - extending
what went before. This has full compatiblity with scrolling and
non-scrolling tables. A throttle is used to not bring IE to its
knees...
- The shim layer call to api.draw() was telling the API to reset the
paging, but it should have been holding it static (as it now does by
passing false in to draw()).
- It is quite common to have a row selection styling in DataTables, so
it makes sense to built this ability directly into the core CSS. It
doesn't add too much extra weight, but it would be a huge pain for
developers to do themselves and also it means I can reuse it in
TableTools / Editor.
- This event allows plug-ins (specifically FixedColumns in this this
case is what I'm thinking of, but others such as FixedHeader could
also benefit) to alter their layout when the column sizing is changed
(for example by a window resize).
- My fix a while back for detecting if a column was no longer available
in a table was duff, since it used $.map which flattens its array
return, but sorting needs a 2D array.
- Fixed by doing our own itteration
- Because of the way _fnExtend() was deep copying objects, but shallow
copying (i.e. references) arrays, the arrays used in the settings
object were actually being shared between all instances of DataTables
on a page.
- This is most noticable in the column filtering, whereby if you apply
a filter to the column of one table, it is applied to all tables!
- The fix is to dump _fnExtend and replace it with a typical jQuery
extend. However, one special consideration is made for the data being
passed it - we absolutely do want that reference to be retained (that
+ the fact that extend is slow on large arrays/objects) so it is
dumped into a temp variable which is then assigned back to the cloned
object.
- This fixed DataTables/DataTables issue #213
- The `settings.aoPreSearchCols` array was being shared between every
table on the table (test using a simple:
$.fn.dataTableSettings[0].aoColumns ===
$.fn.dataTableSettings[1].aoColumns
) which meant that a column filter aplpied to one table would be
applied to all others.
- Fix is to deep copy the search model when adding a columns
- Fixes DataTables/DataTables issue #213
- It is far from uncommon to do `* { box-sizing: border-box; }` at the
top of your CSS these days, including in frameworks, but this could
cause DataTables a little bit of a problem when scrolling both
horizontally and vertically since the padding it adds to the header
linear element to allow it to scroll over the vertical scrollbar would
be folded into the width of the div linear, rather than added to it.
- Fix is to simply set the box-sizing for the linear. I've decided to do
this in Javascript rather than CSS since it is going to be needed
regardless of the CSS being used.
- This commit sees the number of built in type detection and sorting
functions increase to cover the most common cases of use of plug-ins
for DataTables (witht he exception of dates, for which a new first
class plug-in will be created). Specifically, DataTables now has built
in support for:
- Dates (Date.parse())
- Numeric sorting
- Formatted numbers sorting (including currency and thousands
seperators)
- Numbers wrapped in HTML (link tags for example)
- Formatted numbers in HTML
- HTML
Although the numeric sorting plug-ins could have been collapsed down to
just two plug-ins (rather than 4) I decided to do it this way to allow
type based filter formatters to be used with the formatted number types
to allow search for "100,000" or "100000" to match the same data. This
is not built in, but it is possible (and might be in future).
- The goal with these additional functions is to enhance the abilities
of DataTables out of the box to cover the most common cases for data
usage - DataTables is all about making data in tables more accessable
after all! The size cost is ~300 bytes for these additional functions
- In the case of filtering, if there is no filtering extension for the
column type, then the basic string based filter formatting is
performed (i.e. string is always the fallback - there can't be an
error because a function isn't there).
- This commit matches that behaviour in sorting. If you define a column
type as something for which there is no column sorting function, then
the string type will be used rather than resulting in a javascript
error.
