Preamble

When dealing with your own data formatting, it can often be very useful to have DataTables detect data types and sorting them accordingly for types which are not build into DataTables. For this reason plug-in support is provided to allow custom type detection and sorting.

This example shows sorting with a comma (',') for a decimal place. These plug-ins (and others can be found on DataTables.net.

Initialisation code

/* Note 'unshift' does not work in IE6. A simply array concatenation would. This is used
 * to give the custom type top priority
 */
jQuery.fn.dataTableExt.aTypes.unshift(
	function ( sData )
	{
		var sValidChars = "0123456789-,";
		var Char;
		var bDecimal = false;
		
		/* Check the numeric part */
		for ( i=0 ; i<sData.length ; i++ )
		{
			Char = sData.charAt(i);
			if (sValidChars.indexOf(Char) == -1)
			{
				return null;
			}
			
			/* Only allowed one decimal place... */
			if ( Char == "," )
			{
				if ( bDecimal )
				{
					return null;
				}
				bDecimal = true;
			}
		}
		
		return 'numeric-comma';
	}
);

jQuery.fn.dataTableExt.oSort['numeric-comma-asc']  = function(a,b) {
	var x = (a == "-") ? 0 : a.replace( /,/, "." );
	var y = (b == "-") ? 0 : b.replace( /,/, "." );
	x = parseFloat( x );
	y = parseFloat( y );
	return ((x < y) ? -1 : ((x > y) ?  1 : 0));
};

jQuery.fn.dataTableExt.oSort['numeric-comma-desc'] = function(a,b) {
	var x = (a == "-") ? 0 : a.replace( /,/, "." );
	var y = (b == "-") ? 0 : b.replace( /,/, "." );
	x = parseFloat( x );
	y = parseFloat( y );
	return ((x < y) ?  1 : ((x > y) ? -1 : 0));
};

$(document).ready(function() {
	$('#example').dataTable();
} );
