解决方案

您可以使用insertAdjacentHTML，这是最接近的等效替换document.write与currentScript来获取正在评估的脚本的 HTML 元素。

<p>Updated
  <script>
    var modiDate = new Date(document.lastModified);
    var monthName = new Array("January", "February", "March", "April", "May",
      "June", "July", "August", "September", "October", "November", "December");
    var text = monthName[modiDate.getMonth()] + " ";
    text += modiDate.getDate() + ", " + modiDate.getFullYear();
    document.currentScript.insertAdjacentHTML('afterend', text);
  </script>
</p>
