vue问题记录：vue点击返回，关闭当前子页面

    goBack() {
      this.$router.go(-1)// 返回
      //关闭子页面
      this.$store.state.tagsView.visitedViews.splice(this.$store.state.tagsView.visitedViews.findIndex(item => item.path === this.$route.path), 1)
      this.$router.push(this.$store.state.tagsView.visitedViews[this.$store.state.tagsView.visitedViews.length - 1].path)
    }
