vue.js执行mounted的实例

代码如下：

 1 <!DOCTYPE html>
 2 <html>
 3 <head>
 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
 5 <title></title>
 6 <meta charset="utf-8" />
 7 <script src="../js/vue.js"></script>
 8 </head>
 9 <body>
10 <div id="app">
11 <div>{{msg}}</div><button @click="ontime">start</button>
12 </div>
13 
14 <script>
15 new Vue({
16 el: '#app',
17 data: { msg: 0 },
18 methods: {
19 ontime:function(){
20 setInterval(() => {
21 this.msg++;
22 }, 1000);
23 
24 }
25 },
26 mounted: function () { this.ontime(); }
27 });
28 </script>
29 </body>
30 </html>

 

 

就是mounted要执行的函数必须要用function(){}包裹，然后填写在methods里面定义的函数
