vue项目中如何使用tab切换组件

<template>
 <div class="tab-slider">
  <div class="tab">
   <span v-for="(item, index) in items" v-bind:class="{active: actived == index}" @click="toggle(index)">{{item.tab}}</span>
  </div>
  <div class="tab-content">
   <div class="wrapbox clearboth">
    <div class="item" v-for="(item, index) in items">{{item.tabContent}}</div>
   </div>
  </div>
 </div>
</template>
<script>
 export default {
  name: 'tabSlider',
  data (){
   return {
    actived: 0,
    items: [{
     'tab': 'tab1',
     'tabContent': 'content1'
    },{
     'tab': 'tab2',
     'tabContent': 'content2'
    },{
     'tab': 'tab3',
     'tabContent': 'content3'
    },{
     'tab': 'tab4',
     'tabContent': 'content4'
    }]
   }
  },
  methods: {
   //获取图片base64实现预览
   toggle(index){
    this.actived = index;       
    document.querySelector(".tab-content .wrapbox").style.webkitTransform = "translateX(-" + (this.actived * 400) + "px)";

   }

  }
 }
</script>
