window.onscroll=function(){
var oDiv=document.getElementById('div1');
var scrollTop=document.documentElement.scrollTop || window.pageYOffset || document.body.scrollTop;
//oDiv.style.top=document.documentElement.clientHeight-oDiv.offsetHeight+scrollTop+'px';
startMove(document.documentElement.clientHeight-oDiv.offsetHeight+scrollTop);
};
var timer=null;
function startMove(iTarget){
var oDiv=document.getElementById('div1');
clearInterval(timer);
timer=setInterval(function(){
var speed=(iTarget-oDiv.offsetTop)/10;
speed=speed>0?Math.ceil(speed):Math.floor(speed);
if(iTarget==oDiv.offsetTop)
{clearInterval(timer);}else{
oDiv.style.top=oDiv.offsetTop+speed+'px'
}},30);
};
是不是因为window.onscroll的兼容性问题？该如何解决？请大神帮忙指点指点
