Populating Export Fields when DataTable changes

gistfile1.js

//	Add to callback chain from DataTable.fnDrawCallback, assumes target DataTable is global variable called oTable.
function onDataTableSearchSortAndFilterChangeHandler () {
	$( "#sSearch" ).val(
		$( ".dataTables_filter label input" ).val() );

	if( typeof( oTable ) === "undefined" )
		return;

	var	aaSorting=	oTable.fnSettings().aaSorting;

	$( "#iSortingCols" ).val(	aaSorting.length );

	for(	var	iOuterRow=	0;
			iOuterRow < aaSorting.length;
			iOuterRow++ ) {
		$( "#exportForm" ).append( '<input	type=	"hidden"	name=	"iSortCol_' + iOuterRow + '" id=	"iSortCol_' + iOuterRow + '" />' )
		$( "#exportForm" ).append( '<input	type=	"hidden"	name=	"sSortDir_' + iOuterRow + '" id=	"sSortDir_' + iOuterRow + '" />' )

		$( "#iSortCol_" + iOuterRow ).val(	aaSorting[ iOuterRow ][ 0 ] );
		$( "#sSortDir_" + iOuterRow ).val(	aaSorting[ iOuterRow ][ 1 ] );

	}
