Hi,
I''m trying to use a form.select with a a simple javascript alert.
This is my code.
<%= form.select(:entry_type, Entry::TYPES, :prompt => "Select The
Type", :onChange => "alert(''test'')") %>
The form loads without any issue, but onChange is not in the HTML
source. Of course, since the onChange is not in the source, nothing
happens regardless of the list item I select.
Does anybody know what is going on? Why is the onChange not appearing
in the source?
Thanks

the format for the select helper is the following:
select(object, method, choices, options = {}, html_options = {})
so you should use something like:
<%= select(object, method, choices, { :prompt => "Select the
Type"}, {
:onchange => "alert(''test'');"}) %>

It''s a credit to Ruby''s infinite flexibility that Rails can support so many. For example, the above method doesn''t take just one trailing hash. (A trailing hash is how most :foo => :bar magic works, without {}). In this case, Rails takes some fixed arguments, then takes two hashes, one for dynamic options and the other for raw HTML arguments. Research the prototype to your select, and determine which argmument gets the :onchange. -- Phlip http://www.oreilly.com/catalog/9780596510657/ "Test Driven Ajax (on Rails)" assert_xpath, assert_javascript, & assert_ajax --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
