I've been having great difficulty with this simple script. From every thing I've read this should work.

$(document).ready(function(){
    $(".add_to_profile").css("background-color", "yellow");
    $('a.bookmark').click(function (){
        var addedbookmark = function (data) {
           
            var divreturn = 'div.return-'+ data.nid;
            var divbookmark = 'div.bookmark-'+ data.nid;
            $(divreturn).html("bookmark added");
            $(divbookmark).html('<a href="remove_bookmark/'+ nid+'" class="bookmark">Remove Bookmark</a>')
            $(divreturn).html(nid );
        }
        $.ajax(this.href,
        {
            type : 'POST',
            dataType : 'json',
            success : addedbookmark,
            data : "js=1",
        });
 //       return false;
    });
});

The important data is sent as a get, and works fine,  but I need the post to signal that jQuery sent the data.

<?php
var_dump($_POST);
die;
header('Content-type: application/json');

echo json_encode (array(
            'success' => 'added to profile',
            'nid' => 95,
        ));
exit();

All I get is:

array
 empty

It would be great if someone could give me a clue.
