I have made a form validation using ajax post method. But i got the error "Uncaught TypeError: Cannot read property 'success' of null"...Can anybody help me to solve this...?

My Code

$.post("register.php",{uname:uname,pwd:pwd,cfmpwd:cfmpwd,email:email,gender:gender}).success(function(data){


        var obj = jQuery.parseJSON(data);
        $('.chatregalert').fadeIn('slow');
        if(obj.success == 1){
            $('.chatregalert').css('color','#067800');
            $('.chatuname').val('');
            $('.chatpwd').val('');
            $('.chatcfmpwd').val('');
            $('.chatemail').val('');
            $('.chatgender').val('');
        }else{
            $('.chatregalert').css('color','#CC0000');
        }
        $('.chatregalert').html(obj.msg);


    });
    return false;
});

I have tried alert(data) for success...It alert an empty box... How can i fix this..?

Finally i got the solution. The problem is my server doesn't support JSON because the version of my PHP is 5.1.6. The JSON support available only PHP 5.2 and higher versions..

Could you try to do it like this :

$.post("register.php",
       {uname:uname,pwd:pwd,cfmpwd:cfmpwd,email:email,gender:gender},
       function(data){
            var obj = jQuery.parseJSON(data);
            $('.chatregalert').fadeIn('slow');
            if(obj.success == 1){
                $('.chatregalert').css('color','#067800');
                $('.chatuname').val('');
                $('.chatpwd').val('');
                $('.chatcfmpwd').val('');
                $('.chatemail').val('');
                $('.chatgender').val('');
            }else{
                $('.chatregalert').css('color','#CC0000');
            }
            $('.chatregalert').html(obj.msg);
     });
