前提：准备好jquery js库文件，自己根据js文件目录做相应修改。
先看代码：
1.jq_test.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript" src="js/jquery-1.8.0.js"></script>
<script type="text/javascript">
function sumitForm1(){
$.post('jq.php',{username:$('#username').val()},responseRs,'json');
}
function responseRs(rs){
$('#rs').html(rs.username);
}
</script>
<title>jquery测试</title>
</head>
<body>
<form name="form1" id="form1" action=""> <!--此行不需要也可-->
<input type="text" id="username" name="username" />
<input type="button" value="ajax提交" id="getme" onclick="sumitForm1()"/>
</form> <!--此行同form开始标签不需要也可-->
<div id="rs" name = "rs"></div>
</body>
</html>
2.jq.php
<?php
$result = array();
if(isset($_POST['username'])){
$username = $_POST['username'];
$result['username'] = $username;
}else {
$result['username'] = 'this is no username';
}
die(json_encode($result));
?>
