I have some AJAX in my app which works fine to add new people to a list
shown on-screen. The problem comes if I try to delete one of the new
people. Once saved, there is no problem, as there is an id to delete
with. The problem comes when I try to remove a new person from the
screen. The closest I got was a div around all people and a remove of
that div. All the delete links ( one each person) would delete the first
item on the list..(of course since it only had the div holding
everything to use). I tried div_for and content_tag, but each needed an
id to work with..
Please help.. Thanks
some code..
people.html.erb

You have to supply the id. The ''easiest'' thing to do would probably be to have the destroy or cancel button submit via ajax to the destroy method and, if there''s no id, simply re-render your partial to display the ''saved'' household members. If I understand your code correctly, the problem you''re having results from trying to do too much via js in the new method. I''d recommend a ''save'' button on new people.

Take a look at Railscasts #197, I think it might help you find a solution to your problem.
