Click <tr> to check a checkbox

Click <tr> to check a checkbox

I'd like to be able to click anywhere on the table row and have the checkbox be 'checked'. I'm a complete beginner at jQuery. This is actually the reason why I'm starting to learn it!

The HTML:

<table>
<tr>
<td><input type="checkbox" /></td>
<td>Name</td>
<td>Email</td>
</tr>
</table>



The jQuery:
         $("input:checkbox").click(function(){
             if($(this).attr('checked') == 'checked'){
                 $(this).parents("tr").addClass('ready');
              }
              else{
               $(this).parents("tr").removeClass('ready');
            }
         });


This isn't working, however, as I can't get that class to attach to the table row.

Thanks for any help!
