vue使用动态组件实现TAB切换效果完整实例（vue中动态组件）真没想到

<template>
<div id=”app”>
<div class=”top”>
<div
class=”crad”
:class=”{ highLight: whichIndex==index }”
v-for=”(item, index) in cardArr”
:key=”index”
@click=”
whichIndex=index;
componentId=item.componentId;
”
>
{{ item.componentName }}
</div>
</div>
<div class=”bottom”>
<keep-alive>
<component :is=”componentId”></component>
</keep-alive>
</div>
</div>
</template>
<script>
