说实在的代码有点长而且在FF下还不好用，其实就是一点点问题，IE和FF针对位置的定义不同，只要在popImage函数中加点东西就OK，但是他又不回去了，也就是说onMouseOver不好用了，去掉一个FF不支持的方法，OK！咱们看看具体代码：
function popImage(obj,img,href) { var layer = document.getElementById("popImageLayer"); var t=obj.offsetTop; var l=obj.offsetLeft; while(obj=obj.offsetParent){ t+=obj.offsetTop; l+=obj.offsetLeft; } var content = "<table border=0 width=180 height=180><tr><td align='center' valign='middle'>/n"+ "<A href="+href+" target=_blank><IMG src='"+img+"' οnlοad='DrawImage(this,180,180);' onMouseOut='hideLayer();' onMouseOver=high(this) style='FILTER: alpha(opacity=10)'></A></td></tr></table>"; // onClick='hideLayer();' layer.innerHTML=content; layer.style.left =l + 35 -90+"px"; layer.style.top = t+35-90+"px"; layer.style.visibility='visible'; }
