IE7以降のonScrollが効かない件の解決方法

JavaScript

window.onload = function() {
var isIE = 0<=window.navigator.userAgent.indexOf("MSIE");
if(isIE && document.compatMode=="BackCompat"){
document.body.onscroll = ScrollEvent;
}else{
document.documentElement.onscroll = ScrollEvent;
}
}
function ScrollEvent(){
window.status += "s"; // IEのみ
}

こんな感じで宣言する。
