Ruby on Rails

I am having in rendering the onchange:
My syntax is:

<%= f.select  :country, {"Afghanistan" => "Afghanistan",
                "Aland Islands" => "Aland Islands",
                "Zimbabwe" => "Zimbabwe"
                }, :prompt => "Select", :html_options=>{:onchange=>"display();"} %>

Can you point out the mistake in this syntax??

Easy one...

The first hash is Select options, the second is HTML options.  So you're passing :onchange through as an option to the Rails helper, rather than having it pass through to an HTML attribute.  What you want to do is this:

<%= select("test", "type", ["test1", "test2"], {}
{:onchange=>"alert('Test');"} )%>

Note the empty {} after your normal parameter, that's the empty select options, then your :onchange is in the HTML options hash.

Cheers,

Andy
