单击按钮后在输入区域中插入值

Question

我有这个按钮“Cek 状态”...

enter image description here

当我点击这个按钮时，我希望这个输入区域会被自动填充...

enter image description here

我写了一些代码，就像这样...

let handleFokus = (tab) => {
  console.log("yes new tab");
  let inputField = (tab.document.getElementsByName("MonitoringForm[nomor_pkk]").value = noPKK);
  console.log(inputField, "input");
  tab.onload = (e) => {
    console.log("done loading");
  };
};

console.log("klik");
let tab = window.open("https://monitoring-inaportnet.dephub.go.id");
tab.addEventListener("focus", () => {
  handleFokus(tab);
});
tab.focus();

它可以打开一个新选项卡...但输入区域不会自动填充...请帮助我。我的代码有什么问题...
