关于使用H5 download 实现连续下载.......

download() {
      //本地下载函数
      var arr = this.changelist;
      var brr = [];
      var arrk = 0;
      for (var i = 0; i < arr.length; i++) {
        var url = this.url + "/case_manage/v1/man_pro/download/" + arr[i] + "/";
        brr[i] = url;
      }
      var i = 0;
      var timer = setInterval(() => {
        var url = brr[i];
        var a = document.createElement("a");
        a.setAttribute("download", "");
        a.setAttribute("href", url);
        a.click();
        if (i == arr.length - 1) {
          clearInterval(timer);
        }
        i++;
      }, 1000);
      this.$refs.diong.overlist = []
      this.$refs.diong.toggleSelection()
    },
