How do I remove an element class after success?

[Knarf.R]

When the user clicks on a button in the form associated with it's image, I'd like the image to disappear on success. I'm having trouble implementing this. Any advice?\[code\] <script type="text/javascript"> $(document).ready(function() { $(".removebutton").submit(function(event){ event.preventDefault(); $.ajax({ type:"POST", url:"/munch_video/", data: { 'video_id': $('.video_id', this).val(), // from form 'playlist': $('.playlist').val(), // from form 'add_remove': $('.add_remove').val(), // from form }, success: function(message){ alert(message); $('.span8').removeClass('.video_id', this); } }); return false; }); });</script><div class = "span8" style = "width: 900px;"><!-- wrapper div --> <div class='wrapper huluDotCom'> <!-- image --> <div class="image" style="position: relative; left: 0; top: 0;"> <a href = "http://stackoverflow.com/partners/Business/huluDotCom"> <img src = "http://stackoverflow.com/huluDotCom.png"> </a> <!-- munchbutton div --> <div class='munchbutton'> <form method='post' action = '/munch_video/ ' class = 'removebutton'><div style='display:none'><input type='hidden' name='csrfmiddlewaretoken' value='http://stackoverflow.com/questions/13716545/dKrS8NzqPWFLM6u8wJrAeid4nGw1avGK' /></div> <input type="hidden" value="http://stackoverflow.com/questions/13716545/Channel" class = "playlist"/> <input type="hidden" value="http://stackoverflow.com/questions/13716545/huluDotCom" class = "video_id"/> <input type="hidden" value="http://stackoverflow.com/questions/13716545/remove_video" class = "add_remove"/> <input type='submit' class="btn btn-danger" value='http://stackoverflow.com/questions/13716545/Remove from plate'/> </form> </div> <!-- end munchbutton div --> </div> <!-- end image div --> </div> <!-- end wrapper div --> <!-- wrapper div --> <div class='wrapper TheEllenShow'> <!-- image --> <div class="image" style="position: relative; left: 0; top: 0;"> <a href = "http://stackoverflow.com/partners/Business/TheEllenShow"> <img src = "http://stackoverflow.com/TheEllenShow.png"> </a> <!-- munchbutton div --> <div class='munchbutton'> <form method='post' action = '/munch_video/ ' class = 'removebutton'><div style='display:none'><input type='hidden' name='csrfmiddlewaretoken' value='http://stackoverflow.com/questions/13716545/dKrS8NzqPWFLM6u8wJrAeid4nGw1avGK' /></div> <input type="hidden" value="http://stackoverflow.com/questions/13716545/Channel" class = "playlist"/> <input type="hidden" value="http://stackoverflow.com/questions/13716545/TheEllenShow" class = "video_id"/> <input type="hidden" value="http://stackoverflow.com/questions/13716545/remove_video" class = "add_remove"/> <input type='submit' class="btn btn-danger" value='http://stackoverflow.com/questions/13716545/Remove from plate'/> </form> </div> <!-- end munchbutton div --> </div> <!-- end image div --> </div> <!-- end wrapper div --></div>\[/code\]
