求助：封装了一个漂浮对联广告JAVASCRIPT类，设置onclick事件不生效，请问JAVASCRIPT类是怎样处理onclick事件的
各位专家：
由于工作需要，最主要的是为方便代码的管理，最近参考了一些专家的贴子，做了一个漂浮对联广告的JAVASCRIPT类.功能是基本实现了,但在增加一个关闭按钮时，onclick事件不生效，在网上找了好多资料，都找不到合适的。因为网上的对联广告很少是封装成JAVASCRIPT类的。郁闷之下，来这里求救，请各位施主，有心出智慧，有心而无力帮忙顶下该贴。谢谢！！另外附上我写的JAVASCRIPT类，需要的可以参考。代码如下：
<Script Language=Javascript>

说明：该文件为测试文件，保存为htm即可测试,上面的各参数说明：广告链接,广告源地址,在那个窗口打开（为空即在新窗口打开）,图片广告时为alt标题（动画时用不上）,图片宽度,图片高度。分数不多，就20分，请高手不要嫌弃。谢谢！
