Error Parsing JSON giving unexpected token o error

Question

I am having a problem parsing simple JSON strings. I have checked them on JSONLint and it shows that they are valid. But when I try to parse them using either JSON.parse or the jQuery alternative it gives me the error unexpected token o:

<!doctype HTML>
<html>
  <head>
  </head>
  <body>
    <script type="text/javascript">
      var cur_ques_details ={"ques_id":15,"ques_title":"jlkjlkjlkjljl"};
      var ques_list = JSON.parse(cur_ques_details);

      document.write(ques_list['ques_title']);
    </script>
  </body>
</html>

How to solve this error?

Hello @kartik,

Your data is already an object. No need to parse it.

The javascript interpreter has already parsed it for you.

var cur_ques_details ={"ques_id":15,"ques_title":"jlkjlkjlkjljl"};
document.write(cur_ques_details['ques_title']);

Hope it is helpful!

Thank you!!

@Kartik,

Niroj has mentioned perfectly. It's already parsed and ready to use as JSON Object. in case if you want to see the full code. it will look like this.

<!doctype HTML>
<html>
  <head>
  </head>
  <body>
      var cur_ques_details ={"ques_id":15,"ques_title":"jlkjlkjlkjljl"};
      document.write(cur_ques_details['ques_title']);
  </body>
</html>
