Pass selected value in combo as a parameter

Hi,

I have a select in my form:

<%= select @issue_type, "name", @issue_types.collect {|p| [p.name, p.id]} %>

What I need to do is execute a method passing the value selected in the combo. I've tried lot of things, but I couldn't.

@issue_type is created in the controller and I assigned the first value in the collection. Of course, this is the value I only can pass.

To retrieve the value in the combo I've tried with onchange, but... I couldn't make it work

Thanks in advance

Where are you trying to execute the method? In the browser or in the server? If in the browser then you will have to use javascript (in which case it is not really a Rails question), if in the server then put the select in a form and the selected value will be passed in params when the form is submitted.

What I usually do is get things working without Ajax first. Assuming you've done that, does onchange trigger anything in the logs? Using firebug or the developer tools in chrome/safari could tell you a lot too.

Again answering to myself...

I solved the problem by:

1-Using *link_to_remote* using :with clause, and passing as serialize the id of the div that I had to create sourranding the select 2-In the controller, once taked the parm and maked all the operations, use *respond_to* js and reloading the page.

Probably not the best solution... but it works!
