Answer 1

Try to improve your function in a kind like that:

jQuery.parseJSON = function (data) {
   console.log(data + "");
   return JSON.parse(data + "");
};

Ensure that the caller of the $.parseJSON function supplies a correct formatted parameter "data". You can use the debugger of the browser to inspect the caller stack.

Answer 2

I think your issue is related to JSON data. There could be issues with the syntax of the JSON that you are using. I would suggest that you validate the JSON online using some online JSON Validator tools like http://jsonformatter.curiousconcept.com . Once you have corrected the JSON, use the same JSON by hardcoding it in your code to test this scenario.

Hi Got the solution for the above problem. Actually while bundling the js files I removed validate and validate unobtrusive js files and the problem got solved . Thank you to all for helping me
