上传保存了图片的 storefilename 和realname之后用changurl函数转换路径错误提示 can't read property '0'
if (photo !== null && photo !== "" && photo !== "[]" && photo !== "undefined") {
var imageJson = eval("(" + photo + ")");
var realFileName = imageJson[0]["realFileName"];
var storeFileName = imageJson[0]["storeFileName"];
var ownerID =username;
var operateType = "browse";
var url = this.actionUrl + '?realFileName=' + realFileName + '&storeFileName=' + storeFileName + '&ownerID=' + ownerID + '&operateType=' + operateType;
//var url=this.comp("attachmentSimple1").getFileUrl(realFileName,storeFileName,ownerID,operateType);

src = require.toUrl(url);
//alert(src);
}

就是这一段有问题，（var realFileName = imageJson[0]["realFileName"];）

完整代码
//头像路径
Model.prototype.changeUrl=function(){

      var username = justep.Shell.userName.get();

var userData = this.comp('userData');
var row = "";
var photo = "";
userData.each(function(option) {
if (option.row.val('fUserName') == username) {
row = option.row;
}})
if (row !== "") {
photo = row.val('fPhoto');
}

if (photo !== "undefined" && photo !== "" && photo !== null) {
   var src = "";

   if (photo !== null && photo !== "" && photo !== "[]" && photo !== "undefined") {
var imageJson = eval("(" + photo + ")");
var realFileName = imageJson[0]["realFileName"];
var storeFileName = imageJson[0]["storeFileName"];
var ownerID =username;
var operateType = "browse";
var url = this.actionUrl + '?realFileName=' + realFileName + '&storeFileName=' + storeFileName + '&ownerID=' + ownerID + '&operateType=' + operateType;
//var url=this.comp("attachmentSimple1").getFileUrl(realFileName,storeFileName,ownerID,operateType);

src = require.toUrl(url);
//alert(src);
      }

   return src;

}
else{
      return require.toUrl('./main/img/user.png');
   }
}
