<!--- 给li标签绑定click时间,点击该li标签将索引传给函数重新赋值给num--->

{{item}}{{index}}
</li>
</ul>
<div class="tabCon">
<!--- 循环遍历tabContents数组中的元素,v-show绑定事件,当循环的索引等于num中的值,显示该itemCon值 --->
<div v-for='(index,itemCon) in tabContents' v-show="index == num">

<!--这里是js代码-->
<script type="text/javascript">
var vm = new Vue({
