Parsing JSON giving “unexpected token o” error [duplicate]

猿飞云斯丁2020-03-14

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>

Note: I'm encoding my strings using json_encode() in PHP.
