如何用jQuery将元素文本替换为元素title属性值？

To replace the text content of every .timeago element with its own title attribute value, you need to process each element individually. Your current code fails because $('.timeago').text() returns the combined text of all matched elements, not the text of each specific element.

jQuery Implementation #

Use the .each() method to loop through each .timeago element. For each element, retrieve its title attribute and set it as the new text content:

$('.timeago').each(function() {
  const titleText = $(this).attr('title');
  $(this).text(titleText);
});

Vanilla JavaScript Alternative #

If you prefer not to use jQuery, here's the equivalent vanilla JS code:

document.querySelectorAll('.timeago').forEach(element => {
  const titleText = element.getAttribute('title');
  element.textContent = titleText;
});

Example Result #

For your sample element:

<abbr class="timeago" data-datetime="2022-10-30T18:54:39Z" title="10/30/2022 11:54 AM">15 days ago</abbr>

After running the code, it will become:

<abbr class="timeago" data-datetime="2022-10-30T18:54:39Z" title="10/30/2022 11:54 AM">10/30/2022 11:54 AM</abbr>
