<body>
<form action="11.php" method="get" id="form">
<input type="text" name="text" value="wq"><br>
<input type="text" name="pwd" value="123"><br>
<input type="text" name="sex" value="nv">
</form>
<script>
$(function () {
var a = $('#form').serialize();
console.log(a);//text=wq&pwd=123&sex=nv
$.get('11.php', a, function (data) {
console.log(data);//wq
});
});

<?php

echo $_GET['text'];

异步提交
1、参数的顺序要正确：url、data、success、dataType
2、最后一个dataType可以不写，如果写了json，那么返回的数据会自动进行js对象的转化JSON_parse()
