jquery change td color
===

Im trying to change the color of a td cell when I click on it. First it needs to check data on page.php though:

    $(".change").click(function(event) {
        var section = $(this).data('id');
        $.post("page.php", { td: change }, function(data){
            $(this).css('background', '#000'); <------- THIS
            });
        });

How can i make the THIS line work? I understand I need to set `this` to something, but how?
