  let ids = resultArr.map((item) => item.ddtid).join(",");
  doDownload(ids);
}

// 下载文件
function doDownload(ids) {
  downloadAbility(ids).then((res) => {
    res.data.map(function (v, i) {
      let elemIF = document.createElement("iframe");
      elemIF.src = v.url;
      elemIF.style.display = "none";
      let index = v.url.lastIndexOf("/");
      let name = v.url.substring(index + 1, elemIF.src.length);
      download(v.url, {}, name, { Authorization: "Bearer" + getToken() });
      setTimeout(() => {
        elemIF.remove();
      }, 1000);
    });
