在JavaScript中，杀死DOM元素的正确方法是什么？

[英]In JavaScript what is the right way to kill a DOM element?

原文 2012-07-03 20:55:18 7 2 javascript/ dom

I know that I can set it's style to "display: none" 我知道我可以将其样式设置为“显示：无”

However, that just hides it. 但是，这只是将其隐藏。

I really want to kill a DOM element and all of it's children. 我真的想杀死DOM元素及其所有子元素。

The context is that I'm building a desktop-like GUI system (for learning purposes) inside of a DOM, and when a "window" is closed, I want that DIV and all it's children to be removed. 上下文是，我正在DOM内构建类似桌面的GUI系统（出于学习目的），并且当“窗口”关闭时，我希望删除DIV及其所有子项。

Thus, in JavaScript, how to I tell the GC "hey, get rid of this DOM element, it's no longer needed"? 因此，在JavaScript中，如何告诉GC“嘿，摆脱这个DOM元素，它不再需要了”？

Thanks! 谢谢！

2 个解决方案

To remove all elements, I suppose you could set element.innerHTML to an empty string (although I've never tried it myself). 要删除所有元素，我想您可以将element.innerHTML设置为空字符串（尽管我自己从未尝试过）。 Otherwise, you could use element.removeChild(child) , as described here . 否则，你可以使用element.removeChild(child) ，如所描述这里。

jQuery also supports $([selector]).remove([selector]) , which is more flexible in specifying which elements you want to remove at once. jQuery还支持$([selector]).remove([selector]) ，它在指定要一次删除的元素上更加灵活。 There's more information about jQuery remove here . 有一个关于jQuery的更多信息， remove 这里。

What about removeChild ? 那么removeChild呢？
