vue监听组件是否在可视区域

    mounted() {
      window.addEventListener("scroll", this.scrollHandle, true)
    },
    methods: {
      scrollHandle() {
        const offset = this.$el.getBoundingClientRect();
        const offsetTop = offset.top;
        const offsetBottom = offset.bottom;
        if (offsetTop <= window.innerHeight && offsetBottom >= 0) {
          console.log('移出可视区域');
        } else {
          console.log('移出可视区域');
        }
      }
  }
          //移除监听
          // window.removeEventListener('scroll', this.scrollHandle, true);

直接写在组件里就可以
