See the problem?

...
success: function(data){ 
    $("#result").data($data); 
}

You take the data as data but try to access it as $data, which is a different, uninitialized variable.

Also, you cannot use .val() on an a element, use .html() instead to get the inner HTML. You probably want to use .html() instead of .data() on #result also.

Otherwise your example seems all right.
