当我添加外部JavaScript文件时，“grid”函数不再显示为grid。但是当我删除JS时，grid函数又回来了。为什么？
我试图删除JavaScript。

document.addEventListener('DOMContentLoaded', function() {
  // Select all div elements with the class 'time-div'
  const divs = document.querySelectorAll('.container');
  // Convert the NodeList to an array for easier manipulation
  const divArray = Array.from(divs);
  // Sort the array based on the data-time attribute
  divArray.sort(function(a, b) {
    const timeA = new Date(a.getAttribute('data-time'));
    const timeB = new Date(b.getAttribute('data-time'));
    return timeA - timeB;
  });
  // Clear the existing order of divs
  divs.forEach(div => div.remove());
  // Append the divs in the new order
  divArray.forEach(div => document.body.appendChild(div));
});
