简单实现限制uploadify上传个数
function deleteUrl(){
$("body").on("click",".img-wrap .mask span",function(event){
event.stopPropagation();
var qs=$('#file_upload-queue>div');//所有的队列
var id=qs.eq(2).attr('id');//得到第三个队列的id
$('#uploadTowedAccredit').uploadify('cancel',id);//这样就行了，会自动重置队列数量和删除dom对象，不能直接qs.eq(2).remove()，无效
/*
if(!window.confirm("您确定删除附件？")){
return;
}
var imgUrl=$(this).parents(".img-wrap").find("img").attr("src");
deleteImage(imgUrl);
$(this).parents(".img-wrap").remove();
*/
});
};

另外给大家附上jquery+uploadify多文件上传
