I am looking for a way to update the text-value within a textarea from
an Ajax render call inside of a controller. Is there a way to do this
without rendering an the partial containing the textarea?
Thanks,
Andy

just set the value of the textarea element with a RJS
Disregard, I believe I found a working solution with the following:
render :update do |page|
page[‘messages’].value = @messages
end
where ‘messages’ is the id of the textarea and @messages is updated in
the controller with the current state of the text.
Looks to be working, if anyone sees a reason why this may be a problem
and has a better solution I’d love to hear it.

I was looking for this same solution just the other day, so thank you.

This does work for me with text_fields also, although I reference the
element by
page[‘element_id’].value instead of page.element_id.value

Interesting. Thought I tried it both ways, just tried again and it
works. Thanks.

Hi Andy,
I’m trying to clear the input fields on a form and was really glad to
find
this thread. Unfortunately, I’ve tried this just about every way I can
think of and instead of clearing the fields, it’s clearing pretty much
the
whole page. I would really appreciate some help!
The page has a form that allows the entry of two fields. The form
exists
inside a
Thanks in advance,

— Here’s _entry_form.rhtml —
<%= form_remote_tag(:update => ‘ingredient_list’,
:url => {:action => :add_ingredient},
:position => ‘bottom’,
:after => {:action => :clear_entry}) %>
Name:
<%= text_field_tag :name %>
Amount:
<%= text_field_tag :qty %>
<%= submit_tag ‘Add Ingredient’ %>
<%= end_form_tag %>
— and here’s the clear_entry action in the controller ----
def clear_entry
render :update do |page|
page.Entryline.name.value = ‘’
page.Entryline.qty.value = ‘’
end
end

Michael,
You were trying to use a class proxy instead of an element proxy.
Compare the JavaScript generated by the following:
page.email.value = ‘’ # => Email.value = “”;
page[‘email’].value = ‘’ # => $(“email”).value = “”;

Bill,
The :after callback doesn’t make a remote Ajax call and doesn’t really
need to. Try this to reset the fields:
<%= form_remote_tag(:update => ‘ingredient_list’,
:url => {:action => :add_ingredient},
:position => ‘bottom’,
:after => ‘Form.reset(this)’
) %>
This will just call the Prototype form helper to reset your form. If
you are using RJS in your add_ingredient action then you could just do
the resetting from your RJS template.
Just give the form an id with :html => { :id => ‘entry-form’ } and
then in RJS you could use a JavaScript class proxy like follows:
page.form.reset ‘entry-form’
Also, if your controller action ‘add_ingredient’ renders an RJS
template or uses inline RJS then you don’t want to use the :update
option in your link_to_remote method call. This could be causing your
strange problems.
