I have a list of objects that are in a table. Each row of the table  
contains the elements of one object. The rows have dynamically  
generated id’s based on the object.

I’ve created a destroy method for these objects, but I am not sure what  
to put in the rjs to remove the object from the list.

If you’re using tables, as in

, you’ll be very limited to what  
you  
can do with Ajax. Best bet is to just re-render the table.

I’ve developed an app that can delete table rows with an Ajax call. I  
wrote a javascript delete function and call it from rjs. The script  
ultimately uses the built-in remove method:

$(‘my\_row\_id’).remove();

Since you’ve written your own method, have you tried simply:

page['my\_row\_'id].destroy

in your rjs?
