本文实例讲述了vue.js过滤器+ajax实现事件监听及后台php数据交互。分享给大家供大家参考，具体如下：
在vue.js开发时，数据可以使用jquery和vue-resource来获取数据。在获取数据时，一定需要给一个数据初始值。
index.html：
<!doctype html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
<title>
vuejs 过滤器、ajax数据、嵌套循环、if判断、事件监听
</title>
<style type="text/css">
[v-cloak] { display: none }
</style>
</head>
<body>
<div id="app">
<button v-on:click="getData">ajax获取数据</button>
<table>
<tr>
<td >id</td>
<td >姓名</td>
<td >手机号</td>
<td >城市</td>
<td >性别</td>
<td >通过审核</td>
<td >我的学生</td>
<td >操作</td>
</tr>
<tr v-for="(item,index) in list ">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.tel}}</td>
<td>{{item.sex | sexFormat}}</td>
<td>{{item.province}}_{{item.city}}</td>
<td v-if="item.status==1">是</td>
<td v-else-if="item.status==0">否</td>
<td >
<span v-for="stu in item.stu ">
{{stu.name}},
</span>
</td>
<td>
<button v-on:click="edit">修改</button>
<button v-on:click="del(index)">删除</button>
</td>
</tr>
</table>
