Passing this javascript object from jQuery to PHP?

This question stems from this thread.

I've followed the answer below but am having trouble with passing the object into PHP. I think it's only a minor problem but I can't find it.

My ajax call

 $('.actResult').click(function() {
        var result = {};
        $('.actResult tr').each(function(){
            var $tds = $(this).find('td');
            result[$tds.eq(0).html()] = $tds.eq(1).text();
        });
        console.log(result);
        $.ajax({
            type: 'get',
            url: 'userpage.php',
            data: result
        });
        $('.FindResults').dialog("close");
    });

In userpage.php, I'm using this:

echo '<div id="data"><pre>', var_dump($_GET), '</pre></div>';

Possibly I might need to use stringify or json_decode, but this source tells me it's enough to do an ajax call.

The output is giving me an

array(0){
}

Which is strange. The array prints into the console so it's generated properly. The console also tells me the ajax is executed successfully. I'm using $_GET just because $_POST already has so many variables, it's easier to inspect $_GET for this request.

UPDATE:

From the comments below, the ajax call doesn't do anything when the query is successful. So I changed the call:

$.ajax({
            type: 'get',
            url: 'userpage.php',
            data: result,
            success: function(){
                $('#data').text( data );
            }
        });

And the PHP

echo '<input type="text" id="data" /><pre>', var_dump($_GET), '</pre>';

I tried it with a div instead of a textbox. The result still is array(0){}
