This is the first time I've seen the remote_function method but this is
what I think is happening. Your code creates an html <select> tag. The
html_options variable is used to write attributes into the <select> tag,
e.g.
<select id="hello" class="cool_css" onchange="javascript function call">
So your code adds an onchange attribute to the <select> tag, which calls
a javascript function. You've also given the particulars for the
javascript function to construct a request to send to the server when
the javascript function gets called. Then the server will send the
results back to the javascript function. So you need to tell the
javascript function where you want the results to be inserted on the
page. Javascript doesn't automatically do anything with the results.
That is what the :update parameter for remote_function does--it tells
the javascript function what to do with the results, i.e. insert the
results in the specified tag.

So you want to replace the whole page? What if you specified the id of
the <body> tag? If all the layout stuff gets added to the template, I
don't think that will work--you'd end up with another DOCTYPE tag, etc.
inside the <body> tag making your html a mess.
In addition, when you need to replace the whole page, you don't use
javascript to make an ajax request to the server. It sounds like you
need something like the following inside your <select> tag:
<select onchange="window.location.href = '/show?id=74&state_test=' +
this.value ">
I'm a beginner, so I don't know if rails can do that for you. You might
have to write that by hand doing something like this:
<%= select(:state, :state, [['Alabama', 'AL'], ... ['Wyoming',
'WY']], {},
html_options =
{
:onchange => "window.location.href = '/show?id=74&state_test=' +
this.value "
}
%>
