vue复选框获取值的补充

要通过vue的v-model获取选中复选框的值，可以用遍历对象的方式获取，代码如下：

 1 <!DOCTYPE html>
 2 <html xmlns="http://www.w3.org/1999/xhtml">
 3 <head>
 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
 5     <title></title>
 6     <script src="../js/vue2.js"></script>
 7     <script src="../js/vue-resource.js"></script>
 8 </head>
 9 <body>
10     <div id="app">
11         <input type="checkbox" v-model="person.jack" value="jack" id="Jack" /><label for="Jack">jack</label>
12         <input type="checkbox" v-model="person.bob" value="bob" id="Bob" /><label for="Bob">bob</label>
13         <input type="checkbox" v-model="person.alice" value="alice" id="Alice" /><label for="Alice">alice</label>
14         <p>已选：{{person}}</p>
15         <div><button @click="show">显示</button></div>
16         <p>结果：{{result.toString()}}</p>
17     </div>
18 
19     <script>
20         
21 
22         var app = new Vue({
23             el: '#app',
24             data: {
25                 person: { jack: true, bob: true, alice: false },
26                 result:[]//获取选中后的checkbox的数组值
27             },
28             methods: {
29                 show: function () {
30                     this.result = [];
31                     for (var i in this.person) {
32                         if (this.person[i] == true) {
33                             this.result.push(i);
34                         }
35                     }
36                 },
37             },
38         });
39     </script>
40 </body>
41 </html>
