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
