Question

我做的首页有两个板块用到了JS，其中一个是导航栏，一个是竖的折叠CSS滑动栏目，我发现有冲突，要么一个不

个不能收拢折叠，因为两个JS里面都使用了function这个代码命令，请问怎样修改呢？//<![CDATA[
window.onload = function() {
rolinTab("rolin")
}
function rolinTab(obj) {
var list = $(obj).getElementsByTagName("LI");
var state = {show:false,hidden:false,showObj:false};
for (var i=0; i<list.length; i++) {
var tmp = new rolinItem(list[i],state);
if (i == 0) tmp.pShow();
}
}
function rolinItem(obj,state) {
var speed = 0.0666;
var range = 1;
var interval;
var tarH;
var tar = this;
var head = getFirstChild(obj);
var content = getNextChild(head);

这个不是CSS能设定的。你要在不同的页面里分别设置导航条。或者你可以用一个函数来生成导航条，根据调用页面的不同，生成样式不同的导航条。 举个例子：
