最简单的图片预加载~~~随记

<div id="ld">loading precent</div>

<script>
var loadImg=function(imgArray){
	var comp=0;
	var img=[];
	for(i=0;i<imgArray.length;i++){
		img[i] = new Image;
		img[i].src = imgArray[i];
		img[i].onload = function(){ //关键这句，完成加载后 刷新HTML
			comp++;
			$("#ld").html("loading precent"+comp);
			
		};
	}
}

loadImg(["images/building_01.gif","images/mask.png","images/bullet_2.gif","images/fountain.gif","images/grass_01.gif"])
</script>
