环境导入

不想下载了直接用在线的。

<script src="https://unpkg.com/axios/dist/axios.min.js"></script>

简单例子

编写一个data.json

{
  "name": "jie",
  "url": "https://www.cnblogs.com/OfflineBoy/",
  "address": {
    "street": "火星",
    "city": "非洲城",
    "country": "不知道"
  },
  "links":[
    {"name": "MyBlog",
      "url": "https://www.cnblogs.com/OfflineBoy/"},
    {"name": "百度",
     "url": "https://www.baidu.com/"}
]
}

获得数据代码:

<!DOCTYPE html>
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

<div id="app">
</div>

<script src="js/vue.js"></script>
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<script>
    var vm=new Vue({
        el:"#app",
        //钩子函数
        mounted(){
            axios.get(‘../data.json‘).then(response=>(console.log(response.data)));
        }
    });
</script>
</body>
</html>

数据显示在网页

<!DOCTYPE html>
<head xmlns:v-bind="http://www.w3.org/1999/xhtml">
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

<div id="app">
    <div>{{info.name}}</div>
    <a v-bind:href="info.url">jie</a>
</div>

<script src="js/vue.js"></script>
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<script>
    var vm=new Vue({
        el:"#app",
        data(){
            return {
                info:[]
            }
        },
        //钩子函数
        mounted(){
            //response=> 可以理解为去执行后面指定的行为
            axios.get(‘../data.json‘).then(response=>(this.info=response.data));
        }
    });
</script>
</body>
</html>
