Change the Json Format dynamically - json

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.
