请问如何替换DIV的ONCLICK事件中的值？

[fangsky]

.........大图..........
<div class=jqzoom id=spec-n1 onClick="window.open('1.jpg')">
		<img src="1.jpg" height=350 width=350 jqimg="1.jpg" alt="" />
	</div>
....下面小图..
<div id=spec-list>
			<ul class=list-h>
			<li><img src='1-x.jpg' alt=""></li>
<li><img src='2-x.jpg' alt=""></li>
<li><img src='3-x.jpg' alt=""></li>
			</ul>
		</div>

当鼠标移动到小图上后，上面的大图会自动变化，通过以下语句可以更换大图，请问如何同时更换掉onclick中的图片？ 谢谢
$("#spec-list img").bind("mouseover",function(){
var src=$(this).attr("src");
$("#spec-n1 img").eq(0).attr({
src:src.replace("\/n5\/","\/n1\/"),
jqimg:src.replace("\/n5\/","\/n0\/")
});
});

$("#spec-list img").bind("mouseover",function(){
	var src=$(this).attr("src");
	$("#spec-n1 img").eq(0).attr({
		src:src.replace("\/n5\/","\/n1\/"),
		jqimg:src.replace("\/n5\/","\/n0\/")
	});
	document.getElementById("spec-n1").onclick = function (){
		window.open(src.replace("\/n5\/","\/n1\/"));
	}
});
