Answer 1

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

  <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>

Answer 2

使用getElementById和toLocaleDateString

// date.js

document.getElementById('updated-date').textContent = new Date().toLocaleDateString('en-US', { /* new Date(document.lastModified)... */

  month: 'long',

  day: 'numeric',

  year: 'numeric'

})

<p>Updated <span id="updated-date"></span></p>
