Rails - Oct 2007 - how to pass 2 variables to controller from <a href="#" onCli

I want to pass 2 variables (@variableA, @variableB) to my controller
"search" when the following href is clicked:

myView.rhtml:
<li><a href="#"
onclick="Element.show(''spinner'');
  new Ajax.Updater(''resultsTable'',
    ''/search'',{
      asynchronous:true,
      evalScripts:true,
      onSuccess:function(request){
        Element.hide(''spinner'')
      }
    });return false;">
  <b>HOTEL</b></a>
</li>

I need the 2 variables for my condition string, which should work
something like this:

conditions = ["hotel_id = ? AND city_id = ?", @variableA, @variableB]
unless @hotel_id.nil?

Are you hard coding the link like that? Because you are using a help you 
could say:

<%= link_to ''Home'', { :action =>
''home_form'', :id => ''arg_1'', :id2 =>
''arg_2'' } %>

yes, it''s hard coded because of my quite extensive stylesheet (a, b,
ul,
li..)

Thank you guys,

this looks ugly but it works now:

<a href="#"
onclick="Element.show(''spinner''); new
Ajax.Updater(''resultsTable'',''/search?arg1=1&arg2=2'',{
asynchronous:true,
evalScripts:true, onSuccess:function(request){
Element.hide(''spinner'')
}});return false;"><b>HOTEL</b></a>

a better solution:

<%= link_to_remote "<b>HOME</b>", { :url => {
:controller => "search",
:action => "index", :arg1 => "1", :arg2 =>
"2" }, :update =>
"resultsTable", :success =>
"Element.hide(''spinner'')" } %></li>

link_to_remote "<b>HOME</b>"  is certainly not perfect,
but I can live
with this :)

Zoran,

Since you''re hard-coding all of this, an even better solution would be
to use a named route.  You add named routes in the config/routes.rb
file.  Search for ''named route'' and it''ll give you an
example (around
line 10 of a vanilla routes.rb).

In your case you''d probably add something like this:

map.connect
''home'', :controller=>''search'',
:action=>''index'', :arg1=>1, :arg2=>

Then your method call is reduced to:

link_to_remote "<b>Home</
b>", :url=>home_url, :update=>''resultsTable'',
:sucess=>''Element.hide(''spinner'')

As an observation, you might want to also change :success
to :complete.  That way the spinner gets hidden even with an error
response (success only triggers with a 200 response).
