vue iframe页面刷新停留在当前页面

在跳转iframe的时候 把 iframe 存储下来
刷新后判断是否存在保存的iframe
如果有 就赋值

 sliderClick(i, item) {

      this.sIndex = item.id;

      this.toggleSlider = true;

      this.iframeId = item.id;

      this.iframeUrl = item.linkUrl;

      localStorage.setItem("iframeUrl", item.linkUrl);

      localStorage.setItem("iframeId", item.id);

    },

 
mounted() {
    if (localStorage.getItem("iframeUrl") && localStorage.getItem("iframeId")) {
      this.iframeUrl = localStorage.getItem("iframeUrl");
      this.iframeId = localStorage.getItem("iframeId");
      this.sIndex = localStorage.getItem("iframeId");
    }
  },
  created() {
    this.rout();
    this.$root.eventHub.$off("iframesDate");
    this.$root.eventHub.$on("iframesDate", (res) => {
      this.iframeUrl = res.linkUrl;
      this.sIndex = res.id;
      localStorage.setItem("iframeUrl", res.linkUrl);
      localStorage.setItem("iframeId", res.id);
    });
  },
