- 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.
New: New init option fnCreatedRow - very similar to fnCreatedCell but in this case used for TR elements
Updated: fnCreatedCell now also gets the column index passed in
Fix: Call fnRender only once when using using bUseRendered (don't need to call it twice since our internal data cache already has the rendered value stored) sin
ce this can cause some confusion with re-writing the data source value - 4871
