callblueday / form submit forbidden

Created August 19, 2013 01:34

return false is better because it prevents the default behavior of the event and also prevents the page from bubbling up. Note that this is only correct in jQuery event handlers.

	//使用return false来禁用 form的默认submit事件。

	<form method="POST" action="" id="search-form">
	<input type="text" name="keywords" />
	<input type="submit" value="Search" id="sButton" onclick="loadXMLDoc('file.xml')" />
	</form>

	<script>
	window.onload = function() {
	document.getElementById("search-form").onsubmit = function() {

	$this.data('timer', setTimeout(function(){
	$this.removeData('timer');
	doSomething();
	}, delay));
	});
