如何去掉这段代码的 onload？

我想去掉全部加载完才执行 onload 这里要怎么改：
<script type="text/javascript">
function setOnloadEvent(func){
if(typeof window.onload != "function"){
  window.onload = func;
}
else{
    window.onload = function(){
     oldonload();
     func();
    }
}
}
function setCookie(name,value,days) {
}
function getCookie(name) {
}
function skin(){
if(!document.getElementsByTagName) return false;
if(!document.getElementById("skin")) return false;
var skin_id="blue";
if(getCookie("id")!=null){
      skin_id=getCookie("id");
   }
var span_id=skin_id+"_sp";
var span_on=document.getElementById(span_id);
document.body.className=skin_id;
span_on.className="on";
var skinType=document.getElementById("skin");
var skin_nub=skinType.getElementsByTagName("em");
for(var i=0; i<skin_nub.length;i++){
    skin_nub[i].onmouseover=function(){
    var em_id=this.getAttribute("id");
    var skin_id=em_id.split("_")[1];
    var spanList=document.getElementsByTagName("li");
    for(var j=0;j<spanList.length;j++){
       spanList[j].className="";
       if(spanList[j].getAttribute("id").indexOf(skin_id)!=-1)
       {
       spanList[j].className="on";
       }
    }
     document.body.className=skin_id;
   }
  }
}
setOnloadEvent(skin);
</script>

楼主是想让ONLOAD事件无效是不？？？
如果是那样的话，把“setOnloadEvent(skin);”给注释掉就可以了啊
我原来想用这段代码JS切换DIV的id样式, 后来找到了更简单的方法下面这个就用不着了但还要留做备用去掉全部加载就行，这段要等页面所有图片等下载完才出颜色``去掉加载代码就行<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
