JSON.parse: unexpected character

Question

I\'m trying to pass a json from php jquery, after getting into an array of sql query and get the following javascript error.

JSON.parse: unexpected character         


        

Answer 1

I just ran into this in FF10.0.2 with data that looked like:

[ { "firstName": 'Joe', "lastName": 'Smith' } ]

(with multiple objects in the array - shortened for clarity)

It actually parsed OK using eval, though, instead of JSON.parse. (I'm not using jQuery here.)

The problem went away when I changed ' to " for the values:

[ { "firstName": "Joe", "lastName": "Smith" } ]

I thought the " requirement was only for property names, not data values.

You don't need the $.parseJSON call as jQuery automatically does it because if you don't specify a dataType property jQuery tries to guess it and calls the correct function to parse the response before the data is handled to the success function

   $.ajax({
        type: 'POST',
        url:$(this).attr('action'),
        data:$(this).serialize(),
        success:function(data)
        {
          //console.log("SUCCESS " + data);
          var json_cli = data;
        }
    })
