vue和浏览器返回操作一致

methods: {
  goBack() {
    // 返回上一页
    this.$router.go(-1);
    // 关闭当前页面;
    this.$store.dispatch("tagsView/delView", this.$route);
  }
},
mounted(){
  if (window.history && window.history.pushState) {
    history.pushState(null, null, document.URL);
    window.addEventListener("popstate", this.goBack);
  }
},
destroyed() {
  window.removeEventListener("popstate", this.goBack);
}
