Can any one suggest me a way to parse string to json.String variable is holding the json data (exact json data).I want to directly return that string to my kendo grid whic take only json data.Is there a way to directly parse the string to json.
Thanks in advance
Take a look at this library, I believe that will help.

I have a JSON with more or less 75 keys.
I need to receive this JSON and store offline it using Realm.
I do not want to iterate through the keys, since I've heard that there are ways to save a large JSON using a few lines. How can I do this?
EDIT:
My JSON (
I saved on a server away because it's too big)
http://myjson.com/i7e6l
There is no easy, one liner to parse the JSON and store it in Realm, since each JSON response is unique and no framework can have explicit knowledge about the structure of your JSON response without you giving some information to this framework about your JSON.
You will need to write some code either to parse the response or to make a mapping between your JSON response's fields and the properties of your Realm object. If you choose the latter solution, you can use Alamofire Object Mapper to do the JSON parsing automatically, but even then you have to write code for the mapping.
I have a problem where I am unable to de-serialise a Json string to an object in cases where the object already has a Json string in it.
Ex:
Class A {
int a;
String jsonRpresenationOfSomeObject;
// other stuff
}
I am unable to de-serialise an object of the above Class A. I get an exception for the field "jsonRpresenationOfSomeObject"
Custom de-serialiser is not an option for my use case. Am looking for something generic.
Also found no luck with the Gson library.
Would appreciate any help on this.
There is no issue in serializing and deserializing in JSON for the above mentioned scenario of yours.
I have tried and found that the JSON is able to deserialize your class properly.
i think their might be problem with Access-Specifier of your class.
If you still face the problem, then prvide us the sample source.
It gives you a variable called JSON of type id, but how do I manipulate this? Is it a string? Do I have to serialize it first? How exactly do I interact with it?
It is returned in the form of dictionary, you just need to extract the value based on the key. Example :
[JSON valueForKey:#"key"];
You can get more than the basics

Fantastic course, there's very good code about json handling in the photo mania app.
After trying a lot sorry for asking such a trivial question.
Given below screenshot consist of a data that I have successfully received from the server.
I would like to know how to traverse through the data since whenever I try to cast it to something and try a foreach it gives an error.
The actual data sent from the server is a List() type.
I want to know how to cast it to same type and use it here.
I tried casting but it says unexpected token here.
Any help is appreciated.
JSON.parse return type depends on the String you try to parse. See the doc :
Parses json and build the corresponding parsed JSON value.
Parsed JSON values are of the types num, String, bool, Null, Lists of parsed JSON values or Maps from String to parsed JSON values.
From your screenshot, it seems that the return value is a List. You can do something like the following to use it (did you notice the typo in your commented code - .fore) :
final parsedList = JSON.parse(e.data)/*.fore*/;
parsedList.forEach((x){
query('#idData').appendText(x[0]);
query('#idData').appendText(x[1]);
query('#idData').appendText(x[2]);
query('#idData').appendText(x[3]);
});
I ve a JS array, comprising multiple JS objects.
I want to convert JS array to JSON type, & pass that to controller (using AJAX - POST call).
So that I can retrieve the values from the Array of Objects, in my controller & save them in DB.
NB: I ve tried using $.stringify(myArry), but its not able to send data to controller in JSON format. Also I cant use $.toJSON(myArray), as I m not allowed to include a new plugin in our solution. :(
Plz suggest me any other idea.
Else if anyone can let me know how to deserelize the array in cotroller, that I ve sent by using $.stringify(myArry), that would also great.
Something like
var result = JavaScriptConvert.DeserializeObject(inputContent, JsonDataType);
Per this post, it looks like you'll have to add another plug-in:
JSON stringify missing from jQuery 1.4.1?
The Google solution looks good: http://code.google.com/p/jquery-json/
Or just use the JSON object from Crockford: https://github.com/douglascrockford/JSON-js
