[解决办法]
你第六行是哪一行，看不出来是哪个地方
var preBtn = document.getElementById("present");
var linksList = document.getElementById("links");
检查下这两个是否为NULL
[解决办法]
用Firebug跟踪下就知道了。
[解决办法]
那估计是linksList未找到，alert(linksList)试一下是不是Null

在FF下 ie8下 都可以的 360和ie6不行啊

[解决办法]
1.没找到你哪里有调用函数redirect()促发你刚才的报错
2.没找到ID为links的控件。。。

是的 纳闷的就在这里
首页调用的地方也就这里了

[解决办法]
LZ啊，贴代码不是这样子贴的，你只需要把与这个问题有直接关联的代码贴上来就可以了，这样整个文件整个文件的贴，别人看着都……
