fnFilter callback?

somean

Hi,

I am wondering if there is any way to implement a callback once the fnFilter() has been completed? The data in my datatable was fetched from MySQL by php script using server side processing.

Basically I have implemented the "Show and hide details about a particular record" feature from the examples and I want the response row from fnFilter() to be "open", saves one click for the user.

Can I do this? I am still quite new to Javascript. Many thanks for any help.

fnFilter is a synchronous function - so when it completes the table has been filtered. So:

[code]
oTable.fnFilter( 'whatever' );
doSomething();
[/code]
will do it.

The only exception to this is if you are using server-side processing - when the draw becomes asynchronous. In which case you can use fnDrawCallback and oSettings.bFiltered in the callback.

I have server-side processing and I'd like to bind a callback only on a specific fnFilter call. Is it possible?

There are several ways of doing it, but which one will depend upon what you are doing.

1. Based on the code above:

[code]
oTable.fnFilter( filter );
if ( filter === "whatever" ) {
doSomething();
}
[/code]

2. Or you could listen for the 'filter' event ( http://datatables.net/docs/DataTables/1.9.0/#filter ) and again do an 'if' condition checking for the filter value

3. Or you could bind an event listener to the filtering input looking for the value
