vue 中导航类的切换

1.先看一下想要实现的效果

2.这个效果用js很容易，但是vue不允许操作dom

<div class="ranking">
  <div @click="selected(0,$event)" :class="{'active':selectType === 0}">推荐</div>
  <div @click="selected(1,$event)" :class="{'active':selectType === 1}">围观量</div>
  <div @click="selected(2,$event)" :class="{'active':selectType === 2}">价格</div>
</div>

2.js中的代码

methods: {
  selected: function (type, event) {
     if (event.target !== event.currentTarget) return
      this.selectType = type
    }
}
