Hallo -- is there a way anyone know of that I can add a :confirm clause
to a form submit? Something like:
<%= submit_tag 'commit', :confirm=>"are you certain?" %>
Does anyone know how to achieve this?
Cheers,
   doug.

My guess is that would need to go in the onclick handler for the form.

<form .... onclick="return confirm('Are you sure?')">

However, check it in different browsers first!

 <form onsubmit="return confirm('REaLlY?'">

Hi -- the way I did it was like this:
I created a helper method in 'application_helper.rb':

  def confirm_submit_tag(value="submit", msg="Are you sure?")
    "<input type=\"submit\" value=\"#{value}\" onclick=\"return
confirm('#{msg}');\" />"
  end

& then, in the rhtml (inside the form), I can just use

  <%= confirm_submit_tag 'commit', "This will commit the changes you
made." %>

It works well in firefox & IE.
Cheers for the input!
