Examples

Notify whenever DataTables does a draw:

$('#example').dataTable( {
	"drawCallback": function( settings ) {
		alert( 'DataTables has redrawn the table' );
	}
} );

Use API method in the callback to get the data for the rows in the draw:

$('#example').dataTable( {
	"drawCallback": function( settings ) {
		var api = this.api();

		// Output the data for the visible rows to the browser's console
		console.log( api.rows( {page:'current'} ).data() );
	}
} );
