WP上面有个标签云插件相当酷（似乎叫做“wp-cumulus”），之前有网友在问本站首页的那个标签云的实现，这里说来惭愧，这个东西是无意间在网上捡到的，至今我也忘记是在哪里看到的，估计是在网上瞎逛的时候抠下来的- -！其实就是一个flash，然后把它签到网页上面去而已，并不是什么控件啥的。这个东西使用起来比较简单但就是没有api文档啥的...这里把我的使用情况和大家分享一下！
如果懂as的话可以试着反编译出来，本人之前反过一次，不过由于在as方面的知识为零，所以没咋看懂，OTZ......
标签云效果可以看下本站首页（右边偏下方）
标签云Html代码：
<embed src="TagsClound.swf"
wmode="transparent"
allowscriptaccess="always"
quality="low"
flashvars='[jsonData]'
pluginspage="http://www.macromedia.com/go/getflashplayer"
type="application/x-shockwave-flash"
width="250"
height="250">
</embed>
这里关注两个参数，一个是src，就是swf文件的地址，请点击下载：TagsClound.swf，
另外一个是flashvars，这个参数的值是一个json字符串，下面是对这个参数的内容介绍。

以上这些内容作为embed标签的flashvars属性的值，这里为了好看分成好几行，实际使用的时候不应该分行！另外一个需要注意的是，这个插件使用的是GB2312中文编码！！！
