move.js代码如下：
function startMove(obj,json,fn){
var flag=true;
clearInterval(obj.timer);
obj.timer=setInterval(function(){
for (var attr in json)
{
//去当前值
var icur=0;
if(attr=='opacity'){
icur=Math.round(parseFloat(getStyle(obj,attr))*100);
}else{
icur=parseInt(getStyle(obj,attr));
}
//计算速度
var speed=(json[attr]-icur)/8;
speed=speed>0?Math.ceil(speed):Math.floor(speed);
//检测停止
if(icur!=json[attr]){
flag=false;
}
if(attr=='opacity'){
obj.style.filter='alpha(opacity:'+(icur+speed)+')';
obj.style[attr]=(icur+speed)/100;
}else{
obj.style[attr]=icur+speed+'px';
}
}
if(flag){
clearInterval(obj.timer);
if(fn){
fn();
}
}
},30)
}
function getStyle(obj,attr){
if(obj.currentStyle){
//IE
return obj.currentStyle[attr];
}else{
//Firefox
return getComputedStyle(obj,false)[attr];
}
}
