I wrote beforeajax allows the returned content to be displayed in a specific divI was looking at jquery recently, so I re-wrote it using jquery. jquery really means "write less, do more"
<html>
<head>
<title></title>
<script type="text/javascript" src="http://code.jquery.com/jquery-2.1.1.min.js"></script>
<meta charset="utf-8" />
<script>
$(function(){
$("#right").load("test1.php");
$("#left").click(function(){
$("#right").load("test2.php");
return false;//禁止按钮提交
});
});
</script>
</head>
<body>
<div id="left"><a href="#">点击这里</a></div>
<hr />
<div id="right"></div>
</body>
</html>
