JQuery：从Html页面检索特定用户数据

I am trying to get the specific username information from the links below. When one of the links is clicked, the username information should be kept in the var username. However, it is not working. Any help is very welcome.

<!doctype html>
<?php  
$theUsernameDaniel="danielcajueiro";
$theUsernameMarcelo="marcelopapini";
?>
<html>
    <head>
        <meta charset="utf-8" />
        <title>ControllingHiperlinks</title>
        <script src="http://code.jquery.com/jquery-1.4.1.js" type="text/javascript"></script>  
        <script>
            $(document).ready(function() {
                $("a.peoplePage").click(function(event) {

                    var username=$(this).data("username");

                    alert(username);
                    event.preventDefault();
                });
            });
        </script>        
    </head>
    <body>
        <!-- Updated after the answer below of @Pranav-C-Balan -->
        <a class="peoplePage" data-username="<?php echo $theUsernameDaniel ?>"  href=""> Daniel Cajueiro</a>
        <a class="peoplePage" data-username="<?php echo $theUsernameMarcelo ?>"  href="">Marcelo Cajueiro</a>
    </body>
</html>

    Missing "" in your html code

    <a class="peoplePage" data-username="<?php echo $theUsernameDaniel ?>"  href=""> Daniel Cajueiro</a>
<!--................................^................................^.............................-->

<a class="peoplePage" data-username="<?php echo $theUsernameMarcelo ?>"  href="">Marcelo Cajueiro</a>
<!--................................^................................^.............................-->

    Use latest version of jQuery library

    <script src="http://code.jquery.com/jquery-1.9.1.js" type="text/javascript"></script>

    Otherwise use

    var username=$(this).attr("data-username");

    instead of 

    var username=$(this).data("username");
