请参阅我对该问题的评论。很明显，没有问题的描述=>没有答案。



但是，我可以给你一个建议：你对HTML DOM元素的操作越简单，错误的可能性就越小。为了大大简化它，您可以使用jQuery。请参阅Manipulation类别中的jQuery方法：

http://api.jquery.com/category/操纵/ [ ^ ]，

http://api.jquery.com/category/manipulation/dom-insertion-around / [ ^ ] ，

http://api.jquery.com/category/manipulation/ dom-insertion-inside / [ ^ ]，

http://api.jquery.com / category / manipulation / dom-insertion-outside / [ ^ ]。



如果您需要学习jQuery（强烈推荐），请参阅：

http：//en.wikipedia。 org / wiki / JQuery [ ^ ]，

http://jquery.com/ [ ^ ]，

http：//learn.jquery。 com / [ ^ ]，

http://learn.jquery.com/using-jquery-core/ [ ^ ]，

Please see my comment to the question. Quite apparently, no description of the problem => no answer.

However, I can give you an advice: the simpler your manipulations on the HTML DOM elements, the less likely the bugs. To simplify it greatly, you can use jQuery. Please see the jQuery methods in Manipulation category:
http://api.jquery.com/category/manipulation/[^],
http://api.jquery.com/category/manipulation/dom-insertion-around/[^],
http://api.jquery.com/category/manipulation/dom-insertion-inside/[^],
http://api.jquery.com/category/manipulation/dom-insertion-outside/[^].

If you need to learn jQuery (highly recommended), please see:
http://en.wikipedia.org/wiki/JQuery[^],
http://jquery.com/[^],
http://learn.jquery.com/[^],
http://learn.jquery.com/using-jquery-core/[^],
http://learn.jquery.com/about-jquery/how-jquery-works/[^] (start from here).

Good luck,
