Rails - Oct 2005 - Using AJAX to Disable and Re-enable a form field or button.

I was wondering if there is an Ajax helper like:
Element.show(''search-indicator'')

That will allow me to enable or disable a field or button on a form  
so that the user cannot accidentally resubmit the form as it''s being  
processed.

No AJAX required, just a little javascript.

The snippet below works for me.  "commit" is just the default name for
the button generated by <%= submit_tag %>

<%= start_form_tag({:action => ''do_something''},
{:onsubmit =>
"this.commit.disabled=true;"}) %>
  <%= submit_tag ''Do Something'' %>
<%= end_form_tag %>

Not as such, but you can write one yourself. For instance you can  
make an addition to form_remote that will disable
any inputs with "type=submit" and reenable them as soon as the form  
is loaded again.

Besides you have an option of :loading in all remote helpers - there  
you can put an AJAX call to be executed before the
stuff starts to load, and then you get :loaded which allows you to  
reenable the inputs.

As far as disbaling inputs goes - you can just try and whip up one  
yourself (as we finally have at Least Some Feasible
And Understandable Documentation for prototype)
