vue子组件销毁

HTML

<template>
    <!-- 需要销毁的dom -->
    <div v-if="destroy"></div>
    
    <!-- 同普通的dom，组件也是一样 -->
    <component-name v-if="destroy"></component-name>
</template>
 

<script>
export default {
  name: 'HelloWorld',
  data () {
    return {
      destroy: true
    }
  },
  
  methods: {
    destroyDom: function() {
        this.destroy = false
        this.$nextTick({
            this.destroy = true
        })
    }
  }
}
</script>
 
销毁dom直接利用vue的v-if实现就行了，v-if为false时，dom会被移除，true时会被添加重新渲染
注意：this.nextTick(callback)会在DOM更新后回调
