clearInterval(obj.timer); obj.timer=setInterval(function(){ var who=0; ? who=parseInt(getStyle(obj,attr)); alert(who); var speed=(target-who)/5; //已經(jīng)取整了 ?怎么還是出現(xiàn)396px ?而不是400px speed=speed>0?Math.ceil(speed):Math.floor(speed); if(speed==target) { clearInterval(obj.timer); } obj.style[attr]=who+speed+"px"; },30);
\JS動(dòng)畫效果 我怎么我向上取整了 怎么還是差幾px？
