How to parse json response data?

jQuery.parseJSON( json ) // jsonThe JSON string to parse.

Passing in a malformed JSON string may result in an exception being thrown. For example, the following are all malformed JSON strings:

• {test: 1} (test does not have double quotes around it).
• {'test': 1} ('test' is using single quotes instead of double quotes).

Additionally if you pass in nothing, an empty string, null, or undefined, 'null' will be returned from parseJSON. Where the browser provides a native implementation of JSON.parse, jQuery uses it to parse the string.

Perfect Example is:

var obj = jQuery.parseJSON('{"name":"John"}');
alert( obj.name === "John" );
