php+ajax+json 实例代码

html页面:


<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<script type="text/javascript" src="jquery-1.8.2.min.js"></script>
<script type="text/javascript">
 $(function(){
 $("#send").click(function(){
 var cont = $("input").serialize();
 $.ajax({
 url:'ab.php',
 type:'post',
 dataType:'json',
 data:cont,
 success:function(data){
 var str = data.username + data.age + data.job;
 $("#result").html(str);
 }
 });
 }); 
 });
</script>
</head>
<body>
<div id="result">一会看显示结果</div>
<form id="my" action="" method="post">
 <p><span>姓名:</span> <input type="text" name="username" /></p>
 <p><span>年龄:</span><input type="text" name="age" /></p>
 <p><span>工作:</span><input type="text" name="job" /></p>
</form>
<button id="send">提交</button>
</body>
</html>

 php页面:


<?php
header("Content-type:text/html;charset=utf-8");
 $username = $_POST['username'];
 $age = $_POST['age'];
 $job = $_POST['job'];
 $json_arr = array("username"=>$username,"age"=>$age,"job"=>$job);
 $json_obj = json_encode($json_arr);
 echo $json_obj;
?>
 

使用post方式


<script type="text/javascript">
 $(function(){
 $("#send").click(function(){
 var cont = {username:$("input")[0].value,age:$("input")[1].value,job:$("input")[2].value};
 var url = 'ab.php';
 $.post(url,cont,function(data){
 var res = eval("(" + data + ")");//转为Object对象
 var str = res.username + res.age + res.job;
 $("#result").html(str);
 });
 }); 
 });
</script>
