Question

两个js window.onload冲突了，如何才能正常显示，附上代码，求大家帮帮忙！！！！

//第一个脚本//

window.onload = function() {
var oDiv = document.getElementById("tab");
var oLi = oDiv.getElementsByTagName("div")[0].getElementsByTagName("li");
var aCon = oDiv.getElementsByTagName("div")[1].getElementsByTagName("div");
var timer = null;
for (var i = 0; i < oLi.length; i++) {
oLi[i].index = i;
oLi[i].onclick = function() {
show(this.index);
}
}
function show(a) {
index = a;
var alpha = 0;
for (var j = 0; j < oLi.length; j++) {
oLi[j].className = "";
aCon[j].className = "";
aCon[j].style.opacity = 0;
aCon[j].style.filter = "alpha(opacity=0)";
}
oLi[index].className = "cur";
clearInterval(timer);
timer = setInterval(function() {
alpha += 2;
alpha > 100 && (alpha = 100);
aCon[index].style.opacity = alpha / 100;
aCon[index].style.filter = "alpha(opacity=" + alpha + ")";
alpha == 100 && clearInterval(timer);
},
5)
}
}

//第二个脚本//
(function (){

window.onload = function(){
function fixedBar(id, options){
var ele = document.getElementById(id);
if(!ele) return;
if(/msie (\d+\.\d+)/i.test(navigator.userAgent)){
var pageHeight=window.innerHeight;
var d=document;
if(typeof pageHeight!="number"){
if(document.compatMode=="CSS1Compat"){
pageHeight=document.documentElement.clientHeight;
}else{
pageHeight=document.body.clientHeight;
