Observing collection_select + text_field

Rails
1
<%= collection_select(:category, :id, @categories, :id, :name, options ={:prompt => "-Select categories-"}, :class=>"category_dropdown_list") %> 
<td>
    <%= text_field_tag :search, params[:search], :id=>"search_form",

:value=>params[:search] %>

              <%= observe_field 'search_form',
                          :frequency => 0.5,
                          :url => { :controller => 'auth_user',

:action => ‘get_results’ },
:loading =>
“Element.show(‘indicator_gif_id’)”,
:complete =>
“Element.hide(‘indicator_gif_id’)”,
:with => “‘search_text=’ + escape(value)”
%>

I can observe the text_field, but how do I send the current selected
value of the collection_select also. :with => selected item in
collection_select

Thanks!

Try observe_field instead, and leave off the :with.

You don’t need :with most of the time unless you’re trying to change the
field. See the API.

You do need it if you want to submit more than one field. I wrote up
some usages of :with a while back
(:with or :without you: link_to_remote's mysterious parameter - Space Vatican
)
Depending on usage observe_form may be a better fit.

Ooops should have phrased that differently. Fred’s explanation is great,
as
always.

I read through your article Fred, but I’m still lost trying to figure
out how to pass the two values. How do I even access the values?

$(‘comment’).serialize()
Will evaluate to
comment=whatever_is_in_the_field_with_that_id

I saw that in your article…so should I give the collection_select and
text_field id’s and use two of these: $(‘comment’).serialize()?

Yes. One of the examples given was :with => "$(‘message’).serialize()

  • ‘&’ + $(‘comment’).serialize()"
