Question

I’m using Ruby on rails.
Does somebody know how can I insert a javascript function on a combobox?
My combobox takes info from my database (only three rows), I have this:

<%=select("post", "user_id", @usertype.collect {|p| [p.type_user]},{:include_blank => 'None'}) %>

I want the equivalent to:

select id="post_user_id" name="post[user_id]" onChange="showUsersFromThatType()">
option value="">None</option>
option value="boss">boss</option>
option value="student">student</option>
option value="technicial">technicial</option></select>

Thanks!

<%= select_tag("post", @usertype.collect {|p| [ p.type_user, p.type_user ] }, {:include_blank => 'None'})  %>

@usertype is a collection and has variable\method type_user
