html页面：
<html> <head> <meta http-equiv="content-type" content="text/html;charset=utf-8" /> <script type="text/javascript" src="https://www.jb51.net/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>一会看显示结果</div> <form action="" method="post"> <p><span>姓名：</span> <input type="text" /></p> <p><span>年龄：</span><input type="text" /></p> <p><span>工作：</span><input type="text" /></p> </form> <button>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>
