仿flash图片展示控件：

function getStyle(obj, name){    if(obj.currentStyle)    {        return obj.currentStyle[name];    }    else    {        return getComputedStyle(obj, false)[name];    }}function startMove(obj, attr, iTarget){    clearInterval(obj.timer);    obj.timer=setInterval(function (){        var cur=0;                if(attr=='opacity')        {            cur=Math.round(parseFloat(getStyle(obj, attr))*100);        }        else        {            cur=parseInt(getStyle(obj, attr));        }                var speed=(iTarget-cur)/6;        speed=speed>0?Math.ceil(speed):Math.floor(speed);                if(cur==iTarget)        {            clearInterval(obj.timer);        }        else        {            if(attr=='opacity')            {                obj.style.filter='alpha(opacity:'+(cur+speed)+')';                obj.style.opacity=(cur+speed)/100;                            //    document.getElementById('txt1').value=obj.style.opacity;            }            else            {                obj.style[attr]=cur+speed+'px';            }        }    }, 30);}
