Working Example - just as a first hint for further development...

HTML:

Code: 
<span id="code1" style="background-color: #000;">XXXXXXXX</span> 
<a id="link1" href='http://www.google.com'>Reveal Code</a>

Javascript:

$('#link1').click(function() {
    var newtab = window.open($(this).attr('href'), 'title');
    $('#code1').html("SUPERCODE1").css({
        "background-color": "transparent"
    });
    return false;
});
