Subject: Rails: Transmit <select><option> value into link_to()

[Still trying to safely get on the Rails mailing list...]

Rubies:

The great thing about Web programming is there's so many languages to chose 
from - or mix together.

Specifically, an ERb page can contain 3 languages:

<select id="myList">
<% for record in @table %>
    <option value="<%= record.id %>"><%= h(record.name) %></option>
<% end %>
</select>

Okay, that's a combobox with names and values in it.

Now how do I let the user select one option, and send it to the next page 
with link_to()?

<%= link_to 'Go to Next Page',
         {:action => 'goToNextPage', :id => ??? }
 %>

The third potential language is JavaScript, so in theory I could add an 
onclick event to each <option>, or similar, then express the link_to in raw 
HTML...

<a id="linkOut" href="/page/goToNextPage/2">Go to Next Page</a>

...then use the onclick event to change the href attribute.

However, that's not very Railish, and I'm sure there's some feature 
available which my newbescence has overlooked!
