* This is actually compatible with 1.10.0+ but was never documented (it
wasn't an intended feature, but rather an implementation detail. It
is rather useful though, so is now documented.
* `alert` - Alert the error
* `throw` - Throw an error
* `none` - Do nothing
* A function that is called
New: `dt-event error` event that is triggered when an error occurs (regardless of the value of `$.fn.dataTable.ext.errMode`
Previously the whole row was invalidated as a quick workaround for what
I would would be a complex task, but the solution is actually relatively
simple and small in code size, reusing much of the current invalidation
code. The cache data for the whole row is still removed, but the
important part of minimising the DOM interaction is in place.
Fix: Incorrect returns from sub-methods if a selector does not contain any results (DataTables/DataTables #431)
Update: `dt-api iterator()` has a fourth parameter to indicate that a return value is expected
The basic issue here was the `iterator()`'s automatic check to see if a
new API instance should be returned or not. If there are no results from
a selector the iterator will just use the original API instance to
return, but this isn't correct as we expect an empty result set in this
case. This is partly due to the fact that the top level methods (`row()`
for example) will return 2D arrays, while the child methods will flatten
the results, this is parhaps an error in the API, but too late to fix
now.
To address this, `iterator()` now has a parameter to tell it if a new
instance should be used or not. I debated about a new method
`iteratorNew()`, but I think this is just as clear (which isn't very
clear unfortunatly, but just needs to be made clear in the
documentation, which I've updated for this change).
I've added tests for the selectors with `deferRender` enabled. The test
suite is still in desperate need of update...
This is something that has been in DataTables since the version first
vresion and was contentious at that point so while this is a minor code
change, for me it is quite a big change! I feel that this is the correct
operation now, although it does result in rows being moved around where
they might not be needed to if partial pages could be used.
Improved last page calculation when page size is changed on last page.
e.g. Suppose there are total 12 records and page size is set to 5 records/page. Go to last page, which should be 3, change page size to 10. Page#2 should be selected and it should show 2 records on it.
* This reverts the last commit which documented the old behaviour.
Thinking again about it, if you want to modify the rendered data use
`$(cell).html()`.
* When `dt-init columns.data` / `dt-init columns.render` resolve to a
function, that function is executed. Previously this execution was in
the global scope, but in order to be able to use an instance as a data
source for the row (something I wanted as part of 1.10) we need to
execute the function with the instance's scope. A simple `call()` does
this.
* I could add a check to see if the `rowData` is a plain object or not,
but that would add significant overhead to the processing, and this
particular part of the code needs to be very fast. Additionally, I
think it is unlikely that any one was dependant on this being executed
in global scope, so the change is made.
* This fixes DataTables/DataTables #368.
* 1.10.0 had issues when searching for boolean data as the search
extension methods were checking for empty data, but if found they were
using `''` as the term to filter. It should more accurately just use
the given data.
* Relates, the `_empty()` method was considering `false` to be empty,
but not `true`. Both are now considered to be empty.
* `dt-api state()` - get the last saved state
* `dt-api state.loaded()` - get the state that was loaded when the table
was created
* `dt-api state.save()` - trigger a state save
* `dt-api state.clear()` - clear the saved state
* Fix is to convert from hungarian notation to camelCase in a loop for
the array
New: State staving object structure is now full documentated
* The structure has been altered to be camelCase notation like the rest
of the 1.10 API. State loaded from older versions of DataTables will
be silently ignored
* The native `forEach` is suprisingly slow. I had assumed that it would
be faster that a for loop, but it appears that due to the function
execution it is actually much slower. A simple for loop is much better
for performance and we loose nothing since hte API instance is array
like.
* This fixes DataTables/DataTables #364
* It appears that if you have a reference to a DOM node, but that DOM
node is overwritten by use of innerHTML, the reference is destroyed
and you cannot use the referenced DOM node any more.
* This became apparent from using Editor's inline editing mode, where in
IE the inline edit would work only once. No other browser has this
issue but it is in IE7-DC1.
* The workaround is to remove the child nodes first. not ideal at all,
but it does work.
* Searching the internet I didn't find much about this so I've opened an
issue on the IE connect site:
https://connect.microsoft.com/IE/content/content.aspx?ContentID=29582
* DataTables uses custom jQuery events which propagate up through the
DOM, with the custom event being triggered on the table node. Ideally
I'd like to change the event handling to use $().triggerHandler() to
avoid this issue, but as discussed in issue #245 that would mean that
delegated events wouldn't work. Perhaps there should be two forms of
events triggered by DataTables, those which do bubble and those which
do not. `init` is the only one which would _have_ to bubble.
* The workaround for the moment is to check that the settings object in
context of the executed settings handler is the same as the one that
was used in the addition of the event handler.
* This fixes DataTables/DataTables #361
* In particular this fixes the FixedColumns + ColReorder example which
was showing the problem by expanding the columns to the full container
width for each column. See thread 20848 for information.
* V8 strips unknown characters not only at the start of a string given
to Date.parse() but also at the end. So `10%` (for example) was being
detected as a date type.
* This fixes DataTables/DataTables #354
* This is likely to be of more interest to plug-in authors rather than
for general DataTables usage, but I've found myself wanting it a
couple of times recently for plug-ins.
New: `dt-api row().child.remove()` and `dt-api row().child().remove()` methods to provide the ability to remove and destroy child rows
Fix docs: Note that the row().child() method's return value can have an effect on the chaining
* This fixed DataTables/DataTables issue #326.
* Special thanks to `Scottmitch1` (on github) for help with this one!
Dev: Modify the initialisation of _Api - the old method of using `=`
twice on a row caused Chrome's debugger to show it as both names
concatinated which was confusing.
Fix: Remove API "build" code. That was part of the API prototype and the
design moved away from that approach. The code was redundant and unused.
* Originally this was done because it makes removing items a little bit
easier with Array.splice(), however, it doesn't make any sense to go
through the rows in reverse if there might be an interdependency
between the rows.
* It has never been documented what order the rows are filtered in, so I
think this is a safe change to make.
* I've also added the row display index to the parameters passed in
* This fix was partly committed earlier by mistake [b7feaa2]
* The fix is simply to store the draw hold state and make use of it in
the draw scroll callback.
* In IE8 if the DataTables width calculation functions were being
triggered DataTables would clone the table node and then do a jQuery
$().remove() on the cloned node. This was bad in IE8 as it meant that
on the remove the events that were attached tot he original table were
removed as well as the ones on the clone table. IE8 must retain some
kind of link between the original and clone nodes. Using jQuery's
clone() method resolves this.
* See thread 21040 for more information
* Previously the filter builder was created as a string, so we had to
escape quotes, otherwise it could create invalid HTML. That is no
longer the case as we are using jQuery DOM manipulation, so the escape
is redundant and potentially harmful
* See thread 21197
* Due to the manipulation of DOM elements rather than strings for the
length list, the browser was cropping elements which were being cut
short. Fix is to switch back to string manipulation, which can be done
easily using the outerHTML property of the DOM element. This is
supported in all browsers since Firefox 11, so happy to use it here.
* See thread 21170 for more information
* The two data handling functions for each column are now given a forth
parameter if you are using them as a function. This new parameter
gives index position information about the cell in question, as well
as access to the settings object.
* This additional information allows abstraction functions to be created
external to DataTables that can be reused for different columns, with
those abstraction functions now having access to the information about
the cell they are operating on. For example, you might have a number
formatting function which can be reused, and it will determine what
data to read based on the column index given.
* This additional information is required in order to be able to fully
replace fnRender which was removed in DataTables 1.10.
* This fixes DataTables/DataTables #321
* Documentation updated, including an error fix for columns.data
* The error was that the registered cells array was growing on every
call, so the processing took longer and the memory usage went up
* See thread 21063 for details
* 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 $.param
and then decode the created query string, which would be absolutely 100%
comaptible, but would involve additional code and I think this method
provides that 100% compatiblity from reading the jQuery code), and its
shorter.
- The ability to use negative numbers as a column selector for the
column data index was added recently, but that didn't include the
ability to work with negative numbers with the :visible pesudo
selector. This commit adds that ability so you can do:
`table.column("-1:visible")` to always get the right most visible
column
with :name postfix.
- Previously you could use a jQuery selector for columns by using the
:jq postfix, and names were matched otherwise. This is reversed now
for consistency with the rows and cells selectors which treat strings
as jQuery selectors without the :jq postfix.
returned undefined, null etc.
- The base issue was in the instanceof check which has a priority error,
it was:
! obj instanceof _Api
which is the same as:
(! obj) instanceof _Api
which is rubbish.
We want:
! (obj instanceof _Api)
but there is of course a wrapper function, so that needs ot be taken
into account as well. The new logic does just that.
- Because of the manipulation of the initalisation object initialisation
of multiple tables with a single jQuery call (i.e.
`$('.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.
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
