今天，准备写一个关于前后台数据交互，用vue2.0 + Element + vue-cli + resource开发的一个增删改查的实例！
注意：项目源码：

https://github.com/sky-xsk/element-vue-resource-

还有一点注意的是：我用的是公司内部提供的api，所以不在公司内部，是看不到效果的，最主要的还是对源码的参考！放心我会附上图片效果的!

这个简单实例的开发环境是vue2.0 + Element + vue-cli + resource;至于具体安装步骤和环境的搭建我这里不做过多的赘述！直接会把代码写出来，必要时做一些详细的分析！

1.首先是模板代码，这里用到的就是ElementUI；地址http://element.eleme.io/

<template>
  <div id="app">
        <div class="col-md-12">

<script>

    for (var i = 0; i < 32; i++) {

    }
    uid[6] = "4";
    uid[15] = hexDigits.substr((uid[15] & 0x3) | 0x8, 1);
    var uuid = uid.join("");
    return uuid;
