我在标签云中为单词/标签提供了以下简单代码：

<a about="http://localhost/d456c6" href="http://localhost/d456c6" class="tagweight0 Resource">abda</a>

我想通过点击一个词来改变背景。问题是，我不仅只有一个单词“tagweight0”。

这是我的 jQuery 示例代码：

$('tagweight0').livequery('click', function(event) {
    $("tagweight0").toggleClass("select");
    return false;
});

这是有效的，但是单击所有具有“tagweight0”类的单词都具有更改的背景。如何仅更改所选单词而不是所有标签的背景？

编辑：我可以使用“href”或“about”参数进行更改吗？

$('.tagweight0').live('click', function(event) {
    $(this).toggleClass("select");
    return false;
});

只使用css怎么样？

a:active
{
    background: #555555;
}
