Change the Json Format dynamically

Question

My JSON returns something like this

        {
    data: "Business & Investing (0)",
    attr: {
    id: "91",
    rel: "file",
    dataitem: null,
    datatext: null
    },
    children: [ ]
    },
    {
    data: "Stock Exchange & Money (0)",
    attr: {
    id: "92",
    rel: "file",
    dataitem: null,
    datatext: null
    },
    children: [ ]
    },

i want to change like this "Data" to "title" brfore passing it to view

    {
title: "Business & Investing (0)",
attr: {
id: "91",
rel: "file",
dataitem: null,
datatext: null
},
children: [ ]
},
{
title: "Stock Exchange & Money (0)",
attr: {
id: "92",
rel: "file",
dataitem: null,
datatext: null
},
children: [ ]
},

My Dynatree :

  function CreateCatTree(filter) {

        $("#res_catBar").dynatree({
            postProcess: function (data, dataType) {
                alert("hey");

            },
            initAjax: {

                type: "GET",                
                cache:false,
                url: '@Url.Action("Catalog")',
                data: {
                    filter:filter
                },
            },
            onActivate: function (node) {

                var id = node.data.attr.id;
                event.preventDefault();
                 retrieveCatalog(id);
                     return false;
            }          
        });

    }

Answer 1

You may try this in JS:

if (yourJSON.hasOwnProperty("data")) {
    yourJSON["title"] = yourJSON["data"];
    delete yourJSON["data"];
}

Answer 2

Since you seem to use Dynatree:

you may also implement the postProcess(data, dataType) callback in JavaScript, and modify the Ajax result there, before it is passed to Dynatree.

Answer 3

You should make your own class which has your set of defined properties, and that, then can be serialized through Newtownsoft JSON.

I have a TreeNode.cs

public class TreeNode
{

    [JsonProperty("title")]
    public string title { get; set; }

This is called through a web service as:

 List<TreeNode> myTaskListObj = new List<TreeNode>();

And then Deserialize or serializing the data, as needed:

        //De Serialize
        myTaskListObj = JsonConvert.DeserializeObject<List<TreeNode>>(jsonString);

        //Serialize 
        jsonString = JsonConvert.SerializeObject(myTaskListObj, Formatting.Indented);

Hope this helps.
