推荐答案

该表位于另一个域的 iframe 内，因此访问起来很棘手.在那个other域中包含用户脚本，并给它一个 setTimeout 以给表格填充时间:

The table is inside an iframe on another domain, so it's tricky to access. Include the userscript on that other domain, and give it a setTimeout to give the table time to populate:

// ==UserScript==
// @name         drivers
// @match        https://eldclient.trackingmap.eu/drivers*
// @grant        none
// ==/UserScript==

setTimeout(() => {
  const rows = document.querySelectorAll("#app table.table-component tr");
  console.log(rows);
}, 2000);
