Question

How can i achieve the :before and :success with form_for ? The same way we are using it with form_remote_tag.

<% form_remote_tag(:url => {:controller => "test",:action => "backup"},
            :before => %($('message').innerHTML = "";Element.show('spinner')),
            :success => %(Element.hide('spinner'))) do -%>

Answer 1

With a regular form_tag, the “success” part doesn’t really mean anything (because the user will have navigated away to a different page). However, you can mimic the behavior of the “before” part as follows:

<% form_tag({:controller => 'test', :action => 'backup'}, {:onSubmit => %($('message').innerHTML = "";Element.show('spinner'))}) do -%>

Or, with form_for:

<% form_for @object, :html => {:onSubmit => %($('message').innerHTML = "";Element.show('spinner'))} do |f| -%>

Note that the user may only see the spinner for a brief second before they navigate away to the next page.
