	$(document).ready(function() {
		$('#myForm').bind('submit', function() {
			$(this).ajaxSubmit({
				target: '#output'
			});
			return false; // <-- important!
		});

	Use ajaxForm when you want the plugin to manage all the event binding
	for you.  For example,

	$(document).ready(function() {
		$('#myForm').ajaxForm({
			target: '#output'
		});

	When using ajaxForm, the ajaxSubmit function will be invoked for you
