把var?flag=true; ?放到下面我給放那個位置
for(var?attr?in?json){
var?cur=0;
var?flag=true; ? // 放到這里
if(attr=='opacity'){
cur=Math.round(parseInt(getstyle(obj,attr))*100);
//?alert(cur)
}else{
cur=Math.round(parseInt(getstyle(obj,attr)));
}

改完之后，透明度回不到1了，有沒有大神能給我解釋一下啊啊。

如果放到外面就一直為真了啊

把那個 ?flag 標志 放到function函數(shù)里面 ?你試下 看看

你的運行時是什么問題
