Retrieving values of json object in javascript

I am sending an AJAX request to server and retrieving a response as a json object from the server with javascript code to my android application. I know the key values of the json object(ID, name, status, etc.) but I do not know how to get their values.(100, Mark, success, etc.) I need those data for processing for some other task. Can someone please tell me how to extract data from that json object. When I use alert(http.responseText); as follows I get the json object displayed. I need to get the values out of it.

method used to receive response

http.onreadystatechange = function() { //Handler function for call back on state change.
    if(http.readyState == 4) {
        alert(http.responseText);

json object I receive

{"header": {"ID":100,"name:"Mark"},"body":{"status":"success"}}

you will have to eval the http.responseText to get the json object...

but using eval is not recommended, so you can use the json2 library to parse the text into json object..

or else you can even use the library like jquery and use function parseJSON to get it converted to json object

You have to convert The string to an object by doing var response=JSON.parse(http.responseText);

Just treat it like any object - console.log(response['name'])

You need to convert it to a JavaScript object using JSON.parse:

var obj = JSON.parse(http.responseText);

Since some legacy browsers do not have native JSON support you should include json2.js to shim it for those browsers.
