在网上找了好多，不是不能滚动，就是写的比较复杂，下面这个感觉还不错
以下为js代码 ,保存名称与调用名称相同 ,此处采用ad.js:
1
// 这是关闭飘浮广告的宽度，请根据你的广告内容而定
2var hbcms_ad_width = 100;
3
4// 这是关闭飘浮广告的代码，可以换成图片，点击即可关闭
5var hbcms_close_str = '<div onClick="closeBanner();" style="color:gray;font-size:10pt;cursor:hand;text-align:center;width:100%;background-color: #efefef;line-height:200%">关闭</div>';
6
7// 设置左边的广告代码,请自己更换图片地址，或换成flash，或换成纯文字
8// 如果不希望显示左边的广告，可设置为 = '';
9
10//src为flash路径
11var hbcms_left_ad = '<embed src="c.swf" width="100" height="300" quality="high" wmode="window"></embed>' + hbcms_close_str;
12
13
14// 设置右边的广告代码,如果要和左边的广告一致，可设为 = hbcms_left_ad;
15// 如果不希望显示右边的广告，可设置为 = '';
16var hbcms_right_ad = '<embed src="c.swf" width="100" height="300" quality="high" wmode="window"></embed>' + hbcms_close_str;
