Как сделать выполнение php файла после нажатия на кнопку ?

<a href="#" onclick="parse('[xfvalue_gplay]'); return false;" title="Спарсить">Спарсить</a>

function parse(field) {
	$.post(dle_root + 'engine/ajax/mymod.php', {field: field}, function(data) {
		console.log(data);
		// Творю что хочу.
	});
}

<br />
