* 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!)
