您好，3.5版本这个路径下没有这个js

jishuang

文件是在jar中，直接引用就可以用

我是这样写的，不对呀
//图片路径转换
        Model.prototype.getImageUrl = function(imageJson){
               
                var fileID = imageJson[0]["fileID"];
                var docPath = imageJson[0]["docPath"];
                //依靠上述解析出的信息获得路径
                var url = DocUtils.InnerUtils.getdocServerAction({
                     "docPath" : docPath,
                     urlPattern : "/repository/file/view/" + fileID + "/last/content",
                     isFormAction : false,
                     context : this.getContext()
                });
               
                return require.toUrl(url);//"$model/UI2/ERP/SystemWindowsDialog/process/BusDialog/class/img/pic2.png");
        };

你的js中有DocUtils = require('$UI/system/components/justep/docCommon/docUtil');这个引用吗？

Colerterry

加 了你这句话之后变这样了

找到问题了请结贴

少了行这个var imageJson2 = eval("(" + imageJson + ")");
谢谢！
