完美框架

较运动框架更加完好的框架。和json一起使用

function getStyle(obj,attr){
	if(obj.currentStyle)
	{
		return obj.currentStyle[attr];
	}
	else
	{
		return getComputedStyle(obj,false)[attr];
	}
};
function startMove(obj,json,fn){
	clearInterval(obj.timer);
	obj.timer = setInterval(function(){
		var bStop = true;
		for(var attr in json)
		{
			var iCur = 0;
			if(attr == 'opacity')
			{
				iCur = parseInt(parseFloat(getStyle(obj,attr))*100);
			}
			else
			{
				iCur = parseInt(getStyle(obj,attr));
			}
			var iSpeed=(json[attr]-iCur)/8;
			iSpeed=iSpeed>0?Math.ceil(iSpeed):Math.floor(iSpeed);
			if(iCur!=json[attr])
			{
				bStop=false;
			}
			if(attr == 'opacity')
			{
				obj.style.opacity = (iCur+iSpeed)/100;
				obj.style.filter = 'alpah(opacity='+(iCur+iSpeed)+')';
			}
			else
			{
				obj.style[attr] = iCur+iSpeed+'px';
			}
		}
		if(bStop)
		{
			clearInterval(obj.timer);
			if(fn)
			{
				fn();
			}
		}	
	},30);
};
