Ajax without submti button?

Rails
1

I have a drop down list, how can I set it up to send request when
selecting an option rather than pressing submit button after selection?

And how can I save values of checkboxex/radio buttons without submit?

Thanks

Just use add :onchange attribute to your select tag and put in a
remote_function to send your form via AJAX. You can use the prototype
function Form.serialize to send all the form elements.

See here for example:

http://onrails.org/articles/2006/05/01/remote_function-with

<%= select_tag “content_type”,
options_for_select(content_type_options),
{ :onchange =>
remote_function(
:url => {:action => ‘filter_by_content’},
:with => ‘Form.Element.serialize(this)’) } %>

I think observe_field may be what you’re looking for. Radio buttons may
be
problematic, but it works very well with check boxes, drop downs, and
other
form controls.
