vue 滚动加载数据

核心方法：

 handleScroll: function () {
      var scrollTop =
        document.documentElement.scrollTop || document.body.scrollTop;
      var windowHeitht =
        document.documentElement.clientHeight || document.body.clientHeight;
      var scrollHeight =
        document.documentElement.scrollHeight || document.body.scrollHeight;
      if (scrollTop + windowHeitht >= scrollHeight - 2000) {
        if (this.scroll) {
          this.GetSpecialData();
        }
      }
    },
    GetSpecialData() {
      this.scroll = false;
      this.page.pageIndex++;
      this.load(this.page, this.query);
    },

监听：

 mounted() {
    window.addEventListener("scroll", this.handleScroll);
  },
  destroyed() {
    window.removeEventListener("scroll", this.handleScroll, false);
  },
