JSON is undefined

                    This java script exception you will get if your browser less than IE 8 version. Because JSON.stringify  not part of the IE 7 and lower versions.
  To resolve this issues you need to add the reference of Crockford's JSON2

 

 

Download the JSON 2 script file  from following website  https://github.com/douglascrockford/JSON-js 

Add reference to your web page. Run the application now you will not get the  JSON undefined error

Happy coding …..
