AJAX tabs cannot pass instance variable to partial

Rails
1

I have been trying to understand what Flinn said in
http://www.actsasflinn.com/Ajax_Tabs/index.html#

{{Problem }}

I don’t understand how to pass the instance variable to the partial.
in the main html “url_for(:action => ‘test’)” does not seem to pass
the instance @test to the partial. output is ###.

{{CODE}}
{{in main html.erb}}

  • <%= link_to_function('Vendor', "loadPane($('part_pane'), '" + url_for(:action => 'test') + "'),tabselect($('vendor_tab')); paneselect($('vendor_pane'))") %>
  • <%= render :partial => 'test', :object => @groceries %>

      • {{CONTROLLER}}

   def test
@test = "3"

respond_to do |format|
format.html
format.js {
        render :update do |page|
      page.replace_html 'ss', :partial => 'test'
    end
  }

format.xml { render :xml => @test.to_xml }

end
end

{{partial}}

test is <%= @test%>

{{JS library}}
function tabselect(tab) {
var tablist = $(‘tabcontrol1’).getElementsByTagName(‘li’);
var nodes = $A(tablist);
var lClassType = tab.className.substring(0,
tab.className.indexOf(‘-’) );

nodes.each(function(node){
if (node.id == tab.id) {
tab.className=lClassType+‘-selected’;
} else {
node.className=lClassType+‘-unselected’;
};
});
}

function paneselect(pane) {
var panelist = $(‘panecontrol1’).getElementsByTagName(‘li’);
var nodes = $A(panelist);

nodes.each(function(node){
if (node.id == pane.id) {
pane.className=‘pane-selected’;
} else {
node.className=‘pane-unselected’;
};
});
}

function loadPane(pane, src) {
if (pane.innerHTML==‘’ || pane.innerHTML==‘Wait Loading…’) {
reloadPane(pane, src);
}
}

function reloadPane(pane, src) {
new Ajax.Updater(pane, src, {asynchronous:1, evalScripts:true,
onLoading:function(request){pane.innerHTML=‘Wait Loading…’}})
}

{{test.js.rjs}}

page.replace_html(“ss”, :partial => “test”, :object => @test)

Are you expecting the value of @test at the point that main.html.erb
to be preserved until when your ajax request is handled ?

no i got desperate and was just trying to any tactic i knew to get the
instance to the partial. i am trying to push the value from the
controller to the partial. basically the @test = 3.

btw if u guys know of an easier ajax tab method please tell me as well
