Thanks! This really helped me. My book doesn’t mention the :html hash either.

Jen: With a standard form you can do this: <%= form_tag({ :action => :create }, { :onsubmit => 'function call' }) %> However you probably noticed that if you try using :onsubmit with form_remote_tag(), your event handler gets replaced with the Ajax handler set up by Rails. One option for Ajax may be to use the :before callback, which should allow you to call a function before the request is made. I haven't tested it, but that may be what you're looking for.

i am trying to do something similar, but perhaps really wrongheaded. i want to call a javascript function on a rails submit; before the form is submitted i want to dynamically add fields and then send their values. i’d love to use an ajax remote_form_tag to generate the form. i’ve been looking at the html options hash also but can’t find any way of doing something like :onsubmit => “call javascript function”.

do you have any thoughts on this? any help would be much appreciated.

thanks,
jen
