标题: [求助]====每日一帖，我的网页论坛首页怎么有错误
我下载了笨笨给的漂浮广告代码

以下是他的代码

我把这段代码直接加到template\wind下的index.htm，在网页上会出现错误

以下错误的提示；
  1. Line:589
  2. Char:8
  3. Code:0
  4. Error:&#39;document.all.floater.style&#39; 为空或不是对象
  5. 网址:[url]http://172.16.173.250/bbs/index.php[/url]
复制代码

现在我把index.htm文件传上来，请大家看一下，错在了哪里？

这一段
作者: 我是誰    时间: 2005-11-8 12:38
这段代码的错误在于,floater这个对象没有定义.
呵呵,我看出来了,这段浮动效果代码,笨笨同志偷了点懒,把思政网首面上的那段代码复制下来了.而且没作什么改动.  偶曾改写过这一段,所以揪出来啦,嘿嘿
原文中有floater的定义:
  2. <!-- <div ID="floater" style="left: 0px; top: 300px">
  3. <p align="center">
  4. <img SRC="01img\left.gif" border="0">
  5. </div> -->
复制代码
笨笨只是把这段注释掉了.却忘了改JS.所以有这个错误.

如果你想实现浮动效果,把这段HTML代码的注释去掉,再把里面这个图片名换成你要显示的图片就行啦!
作者: 笨笨啊    时间: 2005-11-8 12:46
嘻嘻，是的，因为偷懒，所以就直接复制了，也没有测试-_-#因为那时太晚了，困得不得了
第二天上论坛才得知有角本错误，呵呵
作者: LovGate    时间: 2005-11-8 21:43
晕,怪不得,总是有错误

我不发出来,一直要错下去吗
作者: 笨笨啊    时间: 2005-11-8 21:53
因为这帖子没更新嘛
我自己论坛上的是第二天就修正过来了…………
