I am unable to process the json response ,while accessing the json response I am getting some invalid characters in the json response,so How can we remove white space issues and invalid characters from the json response using php scirpt

My json Response :

And My JQuery is:

$.ajax({
            type:"post", 
            datatype : 'json',
            url:"GetKeyWordBids.php", 
            data:"specialty="+ spevalue,
            success: function(s) {
                var object = $.parseJSON(s);
                /*oTable.fnClearTable();
                oTable.fnAddData([
                    s
                ]); */
            }
        }); 

FireBug Output:

SyntaxError: JSON.parse: unexpected non-whitespace character after JSON data at line 1 column 25230 of the JSON data

And Jsonlint.com output for json response:

Parse error on line 75:
...        "keyword": "ear nose and throat
----------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['

Answer 1

You don't need to use $.parseJSON(); since datatype : 'json' is specified. the returned data is already in the JSON format just use it directly.

Answer 2

Please paste your JSON data here: http://jsonlint.com/ and see that the JSON syntax is bad.

When you'll fix that, use Satpal answer (don't include $.parseJSON)
