- order() and order.listener() added (to replace fnSort and
fnSortListener) from the old API.
- Note that the name `order` is selected to not conflict with the `sort`
method of the API object, which can be used to order the sort data
held in the collection.
- The `sort()` method is expanded over the abilities of fnSort to allow
multiple different forms of input (column + direction, 1D array, list
of 1D arrays or a 2D array).
- draw() and ajax.reload() can now have `false` passed as their first
(and currently only) parameter, which instructs DataTables to do a
'static' redraw (i.e. not to reset the pagination).
- Introducing several methods which will control the ajax aspects of
DataTables through the API:
- ajax.json() - get the last JSON returned from the server
- ajax.reload() - reload from JSON source
- ajax.url( [url] ) - get / set the Ajax URL
- ajax.url( url ).load() - load data from new URL after a set
- Note that this effectively replaces the old fnReloadAjax plug-in which
was quite popular.
- Not yet fully tested - further work required.
- Paging control methods for the new API:
- page() / page(n) - Get / set the current page
- page.info() - Get information about the table's paging state
- page.len() / page.len(n) - Get / set the page length
- Rewrite of core.page.js and core.length.js to be more space efficient.
The functionality is identical to before, but now compresses much
better (796 byte saving). The new paging API methods add only 614
bytes (compressed), so overall a saving of 182 bytes, with the new
functionality added by the new API.
- Start of draw methods for new API:
- draw() - Draw the table. Need this to test the new paging methods
since page() etc do not do a redraw themselves, you must call draw()
when you are ready for the table to be redrawn now.
- tables() is a table selector and iterator that most other API methods
will likely use.
- tables().nodes() gets the selected HTML table nodes.
- Documentation of these functions is rather incomplete. Not yet sure
how to fully document them. Currently thinking of having seperate
documentation, a bit like jQuery, which can be a lot more involved,
rather than building it fromt he doc comments which might get rather
long (they already are!).
- This commit introduces the new Api core, a 'class' which is a data
helper and DataTable control interface. Methods of this class are
designed to be chainable (although it is not manditory - some can
return boolean values if needed).
- The core data helper functions are present in this comment, although
not yet fully documented. That will come as the Api stablises and I'm
happy with the structure.
- There are no table control methods yet - coming soon.
- When server-side processing is enabled, fnInitComplete will now be
passed a second parameter, the json returned from the server for that
first draw, matching the Ajax data source with client-side processing
option.
- Full license available here: http://datatables.net/license_mit
- Note that this effectively makes the BSD and GPLv2 licenses that
DataTables is also available under redundant since the MIT is the most
relaxed of these licenses. At some point in the not too distant
future, it would make sense to remove these two licenses and have
DataTables available under only the MIT license.
used for the different data types very easily.
- Until now, if you want to use different data for the different data
types (I've called these orthogonal data in relations to DataTables)
you had to specify a function. That's fine, but it seems a rather
clumsy way of just pulling different data out of a source object based
on the type. This method allows the data types to be very easily
defined with an object, allowing the same rules as `render` normally
does (dotted object notation, array notation etc).
- For example:
$(document).ready(function() {
$('#example').dataTable( {
columns: [
{ data: null, render: {
_: 'a',
sort: 'c',
type: 'c',
filter: 'd'
} },
{ data: 'b' }
],
data: [
{ 'a': 1, 'b': 2, 'c': 4, 'd': '1' },
{ 'a': 3, 'b': 4, 'c': 3, 'd': '3' },
{ 'a': 5, 'b': 6, 'c': 2, 'd': '5' },
{ 'a': 7, 'b': 8, 'c': 1, 'd': 'allan' }
]
} );
} );
- Tabbing through a scrolling table the tabindex on the cloned header in
the body part of hte table meant that the browser would focus on those
elements. Fix is to remove the tab index from the clone nodes.
- DataTables 1.9 had 5 different parameters that controlled how Ajax
data was obtained, which with its own naming properties, often mapping
to the jQuery.ajax methods, or otherwise extending them. To hugely
simply and extend the Ajax functionality DataTables has, these five
parameters have now been deprecated and the funtionality provided by
them merged into the new `ajax` parameter.
- Deprecated properties:
- sAjaxSource
- fnServerData
- sAjaxDataProp
- sServerMethod
- fnServerParams
- Note that these parameters are still fully supported and can be used,
but for new projects, `ajax` should be used as they will eventually be
removed (likely DataTables v2 whenever that is, as they are too widely
used to be removed in v1.x).
- Added additional / missing tests for the deprecated properties to
ensure full backwards compatiblity
- The new `ajax` property is fully documented in the doc comments, but
as a summary it can take three forms:
- string - the url to get the data from (i.e. this is the new
sAjaxSource)
- object - maps directly to jQuery.ajax, allowing full control of the
Ajax call (provides the abilities of fnServerParams, sServerMethod,
sAjaxDataProp)
- function - a function so you can get the data your own way
(provides the abilities of fnServerData)
- Added unit tests for the new `ajax` property and doc comment examples
updated to use this property exclusively.
- jQuery migrate gives a warning about the use of `attr` rather than
`prop`. However, we should really just be using `val` here - much
easier.
- Thread: 13931
Removed: fnCookieCallback (cookieCallback) - This is now irrelevant since DataTables does not state save in cookies by default.
Removed: sCookiePrefix (cookiePrefix) - This is now irrelevant since DataTables does not state save in cookies by default.
Depreciated: iCookieDuration (cookieDuration) - Since DataTables does not use cookies for state saving by default the name of this parameter is now incorrect. The new parameter `stateDuration` should be used instead, although the old parameter is still supported. It will be removed in the next major version of DataTables.
Update - Performance / Memory: The functions that DataTables uses are not instance based, they are locally scoped, but they were included in the DataTable constructore, which meant that every time you create a new 'instance' of DataTables ($().dataTable()) it would create these functions in that scope again and again. That's completely pointless since we only need them once, so moving them outside the constructor helps both performance and memory (not huge, but very little helps!).
