function closeMeAndReloadParent(){
  opener.location.reload();
  window.close();
}

<span onclick="openNewWindow()">点击打开新窗口</span>
<input type="text" class="parent-input">
<script>
  function openNewWindow() {
    document.querySelector(".parent-input").focus()
    window.open("scrollbymyself.html", "new window");
  }
  document.querySelector(".parent-input").onfocus = function () {
    console.log("获取到了焦点，可以在这里写逻辑代码")
  }
  console.log("页面重新刷新")
</script>

<span onclick="closeCurrentWindow()">点击关闭当前窗口，并且更新上一个窗口的信息</span>
<script>
  function closeCurrentWindow() {
