如何通过javascript更改链接HREF [英] How to change link HREFs via javascript

问题描述

我有一个用户输入网址的表单。稍微调整后输入产生的值是变量#url，它会立即显示给用户。

I have a form where the user inputs an URL. The value resulting from that input after tweaking it a bit is the variable #url which is displayed to the user right away.

我需要制作类似和推文按钮我的网站指向该网址。使他们的HREFS等于变量#ur

I need to make the like and tweet buttons in my site point to that URL. Making their HREFS equal to the variable #url

这是分享按钮：

<a id="twtbutton" href="http://twitter.com/share" class="twitter-share-button" data-count="horizontal" data-via="theclocktwt">Tweet</a><script type="text/javascript" src="http://platform.twitter.com/widgets.js"></script></div>

<fb:like id="fbbutton" send="false" layout="button_count" width="450" show_faces="false" font="" style="position: absolute; left:110px;"></fb:like>
</div>

出现了什么因为改进的链接是我希望共享按钮使用的URL。

What appears as "Improved link" is the url I want the share buttons to use.
