jQuery empty()与remove()

问题描述

jQuery中的empty()和remove()方法之间有什么区别，当我们调用这些方法中的任何一个时，正在创建的对象将被销毁并释放内存?

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?

推荐答案

• empty()将删除所选内容的所有内容.
• remove()将删除所选内容及其内容.
• empty() will remove all the contents of the selection.
• remove() will remove the selection and its contents.

考虑:

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

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

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

它们都是删除DOM对象，应该释放它们占用的内存，是的.

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