Event Handlers in ruby on rails

Rails
1

Does anyone know how I can implement event handlers in rails? I’m a
super newbie to programming in general and wanted to start with a
language that is really simple.

Besides that, I have a little javascript knowledge.

So I was wondering how I could integrate event handlers into my pages?

Ok, I figured out how to include event handlers, it’s like this"<%=
start_form_tag({:action=>‘update’, :id=>@alert},
:onsubmit=>‘getComment()’) %>" but now:

If I want my event handler to trigger an ajax call that works with an
action/method in my rails controller?

Take a look at link_to_remote. It has a hooks for setting javascript
callbacks to run while loading, on success, on failure, etc. Then just
add the action to handle it on the server side and you’re all set.

I’m very sorry. I should have been more specific.

I know how to use, an onclick even handler because that comes with
rails. but for instance, in a form, i’ll have a select element with 3
options, and if a certain option is selected, it will prompt javascript
to have an additional field fade in.

I’m guessing hardcoding it will be the easiest.
