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    lt  doctype HTML gt   lt html gt     lt head gt     lt  head gt     lt body gt       lt script type  text javascript  gt        var cur ques details    ques id  15  ques title   jlkjlkjlkjljl          var ques list   JSON parse cur ques details          document write ques list  ques title          lt  script gt     lt  body gt   lt  html gt    Note  I m encoding my strings using json encode   in PHP

Response is already parsed  you don t need to parse it again  if you parse it again it will give you  unexpected token o   if you need to get it as string  you could use JSON stringify

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

I had the same problem when I submitted data using jQuery AJAX       ajax      url        success function data           server response s data is JSON         I use jQuery s parseJSON method          parseJSON data    it s ERROR            If the response is JSON  and you use this method  the data you get is a JavaScript object  but if you use dataType  text   data is a JSON string  Then the use of   parseJSON is okay

I was seeing this unexpected token o error because my  incomplete  code had run previously  live reload   and set the particular keyed local storage value to  object Object  instead of     It wasn t until I changed keys  that things started working as expected  Alternatively  you can follow these instructions to delete the incorrectly set localStorage value

The source of your error  however  is that you need to place the full JSON string in quotes  The following will fix your sample     lt  doctype HTML gt   lt html gt       lt head gt       lt  head gt       lt body gt           lt script type  text javascript  gt              var cur ques details     ques id   15   ques title   jlkjlkjlkjljl                 var ques list   JSON parse cur ques details               document write ques list  ques title              lt  script gt       lt  body gt   lt  html gt    As the other respondents have mentioned  the object  is already parsed into a JS object so you don t need to parse it  To demonstrate how to accomplish the same thing without parsing  you can do the following     lt  doctype HTML gt   lt html gt   lt head gt   lt  head gt       lt body gt           lt script type  text javascript  gt              var cur ques details    ques id   15   ques title   jlkjlkjlkjljl                document write cur ques details ques title            lt  script gt       lt  body gt   lt  html gt
