  );

  element.style.display = "none";
  document.body.appendChild(element);

  element.click();

  document.body.removeChild(element);
}

var a = [...document.querySelectorAll("table tr")].slice(1);

var cc = a.map(
  (a, i, all) =>
    `echo ${i}/${all.length - 1} \n curl -0 -o ${new Date(
      a.querySelector("td:nth-of-type(1)").innerText // Date
    )
      .toISOString()

    } $(${(() => {
      t = a.querySelector("td a").href;
      b = t.replace("%27);", "").replace("javascript:downloadMemories('", "");
      c = b.split("?");
      return `curl -d "${c[1]}" -X POST ${c[0]}`; // Subcall to curl to get real data url
    })()})`
