elementuitabs组件鼠标滑过触发

1.给el-tabs 添加ref属性

 <el-tabs tab-position="left" ref="navTabs">

2.在mounted中添加调用

  mounted() {
    this.$nextTick(() => {
    this.$refs.navTabs.$refs.nav.$nextTick(() => {
      let target = document.getElementsByClassName("el-tabs__item");
      let that = this;
      for (let i = 0; i < target.length; i++) {
        target[i].addEventListener("mouseover", () => {
          that.$refs.navTabs.handleTabClick(1, String(i));
        });
      }
    });
  });
  },
