Converting a string to JSON object

Question

How do you make JS think that a string is JSON    I have a function which only works if JSON object is passed to it  If I pass a string to it  with same format as JSON  it doesn t work  So I want to make that function think that the string passed to it is a JSON  The string is indeed in the JSON format   I also tried the following  I inputted the string through Ajax   with  handle as  parameter as  JSON   and then when  I passed the result to the function it works   So I deduced the problem is not with the string  How do I convert this string to JSON  If i get same string through ajax request and then passing it to function works  whereas directly passing it doesn t work    The string is as follows             data             id    id1          fields                          id    name1              label    joker              unit    year                        id    name2    label    Quantity                  rows        data here      and closing braces

I had the same problem with a similar string like yours   id 1 field1  someField    id 2 field1  someOtherField     The problem here is the structure of the string  The json parser wasn t recognizing that it needs to create 2 objects in this case  So what I did is kind of silly  I just re-structured my string and added the    with this the parser recognized   var myString    id 1 field1  someField    id 2 field1  someOtherField   myString         myString      var json     parseJSON myString    Hope it helps   If anyone has a more elegant approach please share
