在javascript文件中获取buddypress用户名

从我的buddypress PHP模板中，我通常通过引用用户ID获得任何给定用户的用户名，如下所示:-

<?php echo bp_core_get_username( '{{userID}}' ) ?>

但是我需要从外部Javascript文件中检索用户名。

用户ID已经作为var aData[11]传入。我尝试了以下方法，但没有成功:-

 $('td:eq(3)', nRow).html( '<div class="table-row"><a href="http://www.mysite.com/members/' + <?php echo bp_core_get_username( '"' + aData[11] + '"' ) ?> + '/song/?songsID=' + aData[10] + '"><h4 class="nomargin">' + aData[0] + '</h4></a>' + aData[1] + '</div>' );

我试图返回一个URL…这目前给了我:

http://www.mysite.com/members//song/?songsID=6

当它应该是:

http://www.mysite.com/members/用户名/歌曲/? songsID = 6

任何想法?

编辑:下面是我用来输出JSON的服务器端代码
