如何克隆(和还原)DOM子树

问题描述

我想修改DOM子树并在一段时间后恢复它.如何保存一个子树副本到一边(以便与实际的子树一起玩)?之后如何恢复保存的副本?

I would like to modify a DOM subtree and restore it after a while. How can I save a sub-tree copy aside (to play with the actual subtree)? How can I restore the saved copy afterwards?

推荐答案

如果我没看错，那么我认为您要做的就是:

If I'm reading this right, then I think all you'd need to do is:

var DomTreeCopy = $('parentElementSelector').clone(true,true);

然后重新附加DomTreeCopy(代替原始文件):

And then to re-attach the DomTreeCopy (in place of the original):

$('parentElementSelector').replaceWith(DomTreeCopy);

或者将其添加到原始DOM之外:

Or to add it to the DOM in addition to the original:

$(DomTreeCopy).insertAfter($('parentElementSelector'));
