18.VUE学习之-v-for操作对象与数值

一组数组时的循环

二组数组时的循环

另外可以v for 20 可以直接操作数字

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <script type="text/javascript" src="../js/vue.js"></script>
</head>
<body>
<div id="hdcms">
    <!--item相当于v-->
    <li v-for="(v,k) in test">
        {{k}} - {{v}}
    </li>

    <li v-for="(item,key,index) in user">
        {{index}} - {{key}} -  {{item}}
    </li>
    <hr>
    <li v-for="(item,key) in arr">
       {{key}} - {{item.name}} - {{item.age}} - {{item.sex}}
    </li>
    <hr>

    <table border="1" width="100%">
        <tr v-for="v in 20">
            <td>{{v}}</td>
        </tr>
    </table>
</div>
<script>
    var app = new Vue({
        el: '#hdcms',
        data: {
            user: {
                name: '向军',
                age: '22',
                sex: 'boy'
            },
            arr:[
                {name: '小王',age: '21',sex: 'boy'},
                {name: '小李',age: '22',sex: 'boy'},
                {name: '张三',age: '23',sex: 'boy'},
            ],
            test:['css','js','php']
        }
    });
</script>
</body>
</html>

效果:
