javascript - jQuery empty() vs remove()

Question

What's the difference between empty() and remove()methods in jQuery, and when we call any of these methods, the objects being created will be destroyed and memory released?

Answer 1

• empty() will empty the selection of its contents, but preserve the selection itself.
• remove() will empty the selection of its contents and remove the selection itself.

Consider:

<div>
    <p><strong>foo</strong></p>
</div>

$('p').empty();  // --> "<div><p></p></div>"

// whereas,
$('p').remove(); // --> "<div></div>"

Both of them remove the DOM objects and should release the memory they take up, yes.
