Unable to generate a jQuery dform using the parsed string from the controller

Incorporating dForm into my MVC application has been a smooth process. Creating a form from the JSON string below works perfectly:

 var formdata = {
        'action': 'index.html',
        'method': 'get',
        'elements':
                [
                 {
                  "type":"select",
                  "name":"Name",
                  "caption":"Name",
                  "options":"first":{"html":"first","class":"active"},
                            "second":{"html":"second","class":"active"},
                  "selected":null
                 } 
               ]
  };

However, when I attempt to use the generated elements as shown in the code snippet below:

 var elements = {
                "action": "index.html",
                "method": "get",
                "elements":
                        [
                             $('#jqgrid').jqGrid('getGridParam', 'userData')
                        ]
            };
            $('#myform').buildForm(elements);

I encounter the following error message from dform:

    uncaught exception: No element type given! Must always exist.

Despite ensuring that the "elements" tag mirrors what was originally posted, the issue persists.

Upon inspection with Firebug, I noticed the userData retrieved for jqGrid is in the format:

"userdata":"{\"type\":\"select\",\"name\":\"Name\",\"caption\":\"Name\",\"options\":{\"first\":\"first\" .....

The userData is generated from JObject, leading me to suspect that this might be contributing to the problem. Attempts to address this by replacing the escaping character '\,' have proven unsuccessful.

Answer №1

It seems like the format is not correct. It looks like it is attempting to convert

{ "userdata" : "JSON String" }

Based on my understanding, you may need to try this:

JSON.parse($('#jqgrid').jqGrid('getGridParam', 'userData').userdata);

If that doesn't work, you can visit the Google Group for additional assistance; it might be easier to assist you there.
