chuan,js为之前写的完美运动框架：
function getstyle(obj,name)
{
if(obj.currentStyle)
{
return obj.currentStyle;
}
else
{
return getComputedStyle(obj,false)[name];
}
}
function move(obj,json,fnEnd)
{
clearInterval(obj.timer);
obj.timer=setInterval(function()
{
var bBox=true;//假设所有值都已经到了
for(var strr in json)
{
if(strr=='opacity')
{
var cur=Math.round(parseFloat(getstyle(obj,strr))*100);
}
else
{
var cur=parseInt(getstyle(obj,strr));
}
var speed=(json[strr]-cur)/10;
speed=speed>0?Math.ceil(speed):Math.floor(speed);
if(cur!=json[strr])
bBox=false;
if(strr=='opacity')
{
obj.style.filter='alpha(opacity:'+(cur+speed+')');
obj.style.opacity=(cur+speed)/100;
}
else
{
obj.style[strr]=cur+speed+'px';
}
}
if(bBox)
{
clearInterval(obj.timer);
if(fnEnd)fnEnd();
}
},30);
};
