bind-ref关联的data有数据吗？没有数据就新增一条

181379280

Model.prototype.attachmentPC1Start = function(event){
                debugger;console.log("file start:" + this.printEvent(event));
                var size = event.event.file.size;
                if(size > 10*1024*1024){//大小小于10MB
                        alert("文件上传需小于20M！");
                        event.cancel = true;//终止上传
                }
        };
var localDocParentName ="/upLoad";       //在.w文件同目录下有一个文件件夹upLoad
Model.prototype.modelLoad = function(event){
                this.comp("attachmentPC1").subPath = localDocParentName;
        };


上传按扭：{"operation":"upLoadInsurance.save"}
data-refmodel.upLoadInsurance.ref("docName")

确认上传，报错，如图！！

现在上点上传保存时，出错。

181379280

现在可以保存了，但上传后的图片不在/upLoad目录下。
[{"docID":"C758859E2B500001757DC840DBD012AC","docName":"20161220170742.png","docPath":"/defaultDocNameSpace","fileID":""}]

var localDocParentName ="/upLoad";       //在.w文件同目录下有一个文件件夹upLoad
Model.prototype.modelLoad = function(event){
                this.comp("attachmentPC1").subPath = localDocParentName;
        };
上传的图片在那个文件夹下？

jishuang

这个是设置文档中心的子目录的不是说上传到.w同级的upload目录中

附件最终的文件是否在文档服务器上的，默认是model同级的data\doc下
