var imgObjs = [],
count = 0;rotate.prizeTotal = prizes.length;//图片总数
var timer = setInterval(function() {
if (count == rotate.prizeTotal ) {
clearInterval(timer);
//加载后执行的回调函数
}
}, 50);for(var i = 0;i < prizes.length; i++){
var img = new Image();
img.src = prizes[i].prize_icon; //prizes数组的prize_icon存放图片的地址
imgObjs.push(img);
img.onload = function(){
count++;
}

//获取当前时间yyyymmdd格式var CurrentDate = "";
var day = new Date();
var Year = day.getFullYear();
var Month = day.getMonth()+1;
var Day = day.getDate();
CurrentDate += Year;if (Month >= 10 ){
CurrentDate += Month;
}else{
CurrentDate += "0" + Month;
}if (Day >= 10 ){
CurrentDate += Day ;
}else{
CurrentDate += "0" + Day ;
