Pass variables inside the page

Rails

Hi!

I need to create a combobox which , depending on the selected value,
will display different items whithout reloading the page

<%= select(“product”,“choice”, Pricebooks.find(:all).collect { |p|
[p.name,p.id]}, {:selected => Pricebooks.find(:first)} , {onchange =>
???)%>

How can i retrieve the value of the selected product through onchange?

thanx in advance

is this entirely client side or do you want to make an ajax request ?

That’s pure JS then.

onChange(this), and treat it accordingly…

well, you can submit a classic form request and reload the whole page,
or
submit an ajax request and then update just a part of your page. I think
that you should decide what you want do, then hack this solution. Not
decide
what you want to do because it seems simpler to do.
