当我删除父本身时，是否需要删除DOM元素的所有子元素？

Question

If I delete a parent element, do the child elements remain in the browser's memory?

<div id="parent">
    <ul>
        <li>one</li>
        <li>two</li>
        <li>one</li>
    </ul>
</div>
<script>

    var element = document.getElementById("parent"); 
    element.parent.removeChild(element);

</script>

Answer 1

No, they don't, don't worry. :)

Answer 2

如果孩子们留在内存中，这将成为浏览器代码中的一个非常重大的缺陷和巨大的内存泄漏。

Answer 3

I hope you mean parentNode there :). parent is for accessing a parent frameset or window I believe.

It won't remain in memory if removed. Otherwise a lot of memory would be leaking with objects in the DOM with no pointer to them.

Answer 4

The child nodes are removed and taken care of they don't stay back in memory..

Alternative to your code you can use...jQuery

$('#parent').empty().remove();
