请大家帮忙看看这两段代码

这是一个关于导航条鼠标触碰伸缩的JS，第一个可以实现，但第二个我把函数从循环里拿出来后就不行了，看了好久也没找到原因，请大家看下，求指教！

window.onload=function(){
    var aA=document.getElementsByTagName('a');
	for(var i=0; i<aA.length; i++){
		aA[i].onmouseover=function(){
			var This=this;
			clearInterval(This.time);
			This.time= setInterval(function(){
					This.style.width=This.offsetWidth+8+"px";
					if(This.offsetWidth>=160)
					clearInterval(This.time);
				},30);
		};
		aA[i].onmouseout=function(){
				clearInterval(this.time);
				var This=this;
				this.time=setInterval(function(){
					This.style.width=This.offsetWidth-8+"px";
					if(This.offsetWidth<=120){
						This.style.width='120px';
						clearInterval(This.time);
					}
				},30);
		};
	}
};

window.onload=function(){
    var aA=document.getElementsByTagName('a');
    for(var i=0; i<aA.length; i++){
		aA[i].onmouseover(mouseOver());
		aA[i].onmouseout(mouseOut());
	}

	function mouseOver() {
			var This=this;
			clearInterval(This.time);
			This.time= setInterval(function(){
					This.style.width=This.offsetWidth+8+"px";
					if(This.offsetWidth>=160)
					clearInterval(This.time);
				},30);
		}
		
	function mouseOut(){
		    var This=this;
			clearInterval(this.time);
			this.time=setInterval(function(){
				This.style.width=This.offsetWidth-8+"px";
				if(This.offsetWidth<=120){
					This.style.width='120px';
					clearInterval(This.time);
				}
			},30);
	}
};

aA[i].onmouseover(mouseOver());

aA[i].onmouseout(mouseOut());
把这两个改为

aA[i].onmouseover=mouseOver；

aA[i].onmouseout=mouseOut；

[u011294633]

window.onload=function(){

var aA=document.getElementsByTagName('a');

for(var i=0; i<aA.length; i++){

aA[i].onmouseover=function(){mouseOver(aA[i]);}

aA[i].onmouseout=function(){mouseOut(aA[i]);}

}



function mouseOver(y) {

var This=y;

clearInterval(This.time);

This.time= setInterval(function(){

This.style.width=This.offsetWidth+8+"px";

if(This.offsetWidth>=160)

clearInterval(This.time);

},30);

}



function mouseOut(y){

var This=y;

clearInterval(this.time);

this.time=setInterval(function(){

This.style.width=This.offsetWidth-8+"px";

if(This.offsetWidth<=120){

This.style.width='120px';

clearInterval(This.time);

}

}
