想了想，还是把之前的补齐，先放个封装的运动吧

//获取非行间样式

function getStyle(ele,attr){

return ele.currentStyle ? ele.currentStyle[attr] : getComputedStyle(ele,null)[attr];

}

function move(ele,json,fn){ //json的接收 {width:10900}

//清除定时器

clearInterval(ele.timer);

//开启定时器

ele.timer = setInterval(function(){

var mStop = true;

//遍历json

for(attr in json){

//获取变换的属性的值

var iCur = getStyle(ele,attr);

//判断是否为透明

if(attr == 'opacity'){

iCur *= 100;

}else{

iCur = parseInt(iCur);

}

//设置速度

var speed = (json[attr] - iCur) / 8;

//速度取整

speed = speed > 0 ? Math.ceil(speed) : Math.floor(speed);

//判断

if(iCur != json[attr]){

mStop = false;

}

//运动的逻辑

if(attr == 'opacity'){

ele.style.opacity = (iCur + speed) / 100;

ele.style.filter = 'alpha(opacity='+(iCur + speed)+')'

}else{

ele.style[attr] = iCur + speed + 'px';

}

}

if(mStop){

clearInterval(ele.timer);

if(fn){

fn();

}

}

},30)

}
