New to jQuery

New to jQuery

I have searched everywhere on google and can't find exactly what I need so I hopefully someone can help me here.

I have a list of friends listed for a user on his profile page and I want the ability for him/her to delete a friend if they would like by clicking an 'X' image so I have two functions in php. One that pulls out the firends and echos them in a table and the other that deletes a given friend.

Here is the jquery and html I am using:

'<script type="text/javascript">
            function osmajax(thediv, subaction, user, mem)
            {
                $.ajax({
                   type: "POST",
                   url: "'.$scripturl.'?action=chat",
                   data: "sa=+subaction+&u=+user+&m=+mem+&ajax=1",
                   success: function(resp){
                     $(#+thediv+).html(resp);
                   }
                 }); 
            }
         </script>';


Which is in the head section. And the html where the image is:

<div id="friends">
<table>
foreach ($friends as $key => $value)
        {
            echo    '<tr>
                        <td align="left" style="padding: 2px 0px 2px 7px;"><a href="'.$scripturl.'?action=profile;u='.$key.'">'.$value['name'].'</a></td>
                        <td align="center" style="padding:2px;">'.$value['status'].'</td>
                        <td align="center" style="padding:2px"><a href="#" onclick="osmajax(\'friends\', \'deletefriends\', \''.$key.'\', \''.$context['user']['id'].'\');"><img src="'.$settings['images_url'].'/icons/quick_remove.gif" border="0" alt="'.$txt['chat_delete'].'"></a></td>
                    </tr>';
        }
</table>
</div>


I am using SMF in case you were wondering about the variables. But I can't get it to work. Any help would be great
