- 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.
- Th old comma as a decimal place plug-in isn't needed anymore since
DataTables now has that ability built in using the `thousands` and
`decimal` options
- 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.
- The piplining example didn't have any method to submit additional data
with the Ajax request, other than to modify the library function.
- This commit adds a `data` option which provides the same functionality
as the `ajax.data` option in DataTables - i.e. it can be an object or
function
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
- Added new orthogonal data example
- Updated columns.data and columns.render documentation
- Reordering the manual a little
- Add note to the old orthogonal data blog post to direct people to the
new manual page
