function showPopupText(){
var o=event.srcElement;
MouseX=event.x;
MouseY=event.y;
if(o.alt!=null && o.alt!=""){o.dypop2=o.alt;o.alt=""};//////////o.alt是什么意思呀??????
if(o.title!=null && o.title!=""){o.dypop2=o.title;o.title=""};//o.dypop什么意思呀??
}
document.onmouseover=showPopupText;//-->

o.alt o.title 相当于a 里面的 alt ttitle
o.dypop 应该是自定义的属性 你可以更改别的名字dypopLayer.filters.Alpha.opacity
dypopLayer 应该是一个对象, 参考OBJECT 对象的属性
