为什么我的加载页没效果，直接重0就跳过去了，调试看数组也遍历过了，就是没执行触发load事件后的代码

$progress = $('.progress');
$('.btn').on('click',function () {
if($(this).data('control') ==='prev'){
/*now先自减1再和0比较 若小于0则赋给now*/

}
document.title = (now+1)+"/"+len
$('#img').attr('src',imgs[now]);
});
$.each(imgs,function (i,src) {
/*图片加载完会触发load事件，出错触发error事件*/
var imgObj = new Image();
/*绑定load事件*/
$(imgObj).on('load',function () {
$progress.html(Math.round(count+1/len * 100)+'%');
if(count>=len-1){
$('.loading').hide();
document.title='1/'+len;
}
count++;
});
imgObj.src = src;
});
</script>
</body>
</html>$('#img').attr('src',imgs[now]);和imgObj.src = src; 前者是从数组中获取图片的路径，后者又是干什么啦……
问题差不多想清楚了，我的图片太大，有的浏览器不显示，有的从缓存拿还需要一段时间
