upload的choose，解决confirm不同步

重新调用一次upload就可以了

 

 

给个变量

var uploadIns = upload.render
var isConfirm = false;

choose方法中

,choose:function(){

 //。。。。。。。。。。。。。。。省略

    if(!isConfirm){
        layer.confirm('is ok ？', 
        function(index){layer.close(index);isConfirm = true;uploadIns.upload();});
    }
    return isConfirm;

}
