- Showing and hiding details about a row in a child row is very useful
and proven to be a popular part of DataTables. This commit provides
that ability in the new API and extends it. It also fully modularises
the child rows aspects, so it could be removed from the core without
effecting any other aspects (it may be moved into a seperate file in
future).
- This will effectively replace fnOpen, fnClose and fnIsOpen
- Added methods:
- row( selector, opts ).child()
- row( selector, opts ).child( str, class )
- row( selector, opts ).child( str, class ).show()
- row( selector, opts ).child( str, class ).hide()
- row( selector, opts ).child.show()
- row( selector, opts ).child.hide()
- row( selector, opts ).child.isShown()
- Note that unlike the old API you need to specify the data first, and
then use the show() method to show the child row. This allows the
details rows to be configured before they are actually shown.
- Additionally multiple child rows can be attached to a parent (pass
`str` (from above) as an array to use this feature. API plug-ins could
use this ability to show fully nested tables.
- Not just a string can be passed in now, but also a TR node which will
actually be used (rather than put into a nested row), any other type
of node (which will be inserted into a wrapper row/cell) or a jQuery
object.
- Rather than using Javascript to show a placeholder, use the HTML5
`placeholder` attribute. That is what it is there for and is supported
by all current shipping browsers (IE9- do not support it, but will not
break)
minor improvement: calculate index based on the element's parent th.
this is better because it allows to have some columns that are not searchable (like when the first row is a checkbox row)
New: Static API method - fnIsDataTable - check if a TABLE node is a DataTable or not
New: Static API method - fnTables - get the DataTables that are initialised on the table (optionally limit to just the visible tables)
Examples update - Tabs and scrolling updated to use the new static fnTables method
Fix: Settings object model was missing the nScrollHead and nScrollFoot properties from the documentation
New: The distance from the end of the current scrolling container before new data is added (with infinite scrolling) can be controlled with iScrollLoadGap (which is a numeric value in pixels).
New: Example (basic_init/scrolling_y_infinite.html) to show how infinite scrolling can be used.
Fixed: iDraw was not being incremented for a draw that did not use server-side processing.
