Rails - Sep 2009 - How to get value from link_to_remote's :with paramenter?

Hello,

I have following code in my view
--------------------------------------------------------------
#plan_discount
    %table
      %tr
        %td
          ="Discount Code"
        %td
          =text_field_tag ''discount_code''
        %td
          =link_to_remote "Apply", :update => "result",
:url => {
:action => "discount_code"}, :with =>
"''discount=''+
$(discount_code).value"

#result
//Here I display processed value based on value entered in
"discount_code" //textfield
------------------------------------------------------------------


When user enter the value in discount code textfield, I process it and
display it in "result" div


My problem is that in controllers

How can I get value of "discount" which is passed as a parameter in
above link_to_remote function

 def discount_code
  discount_code = params[:discount]  # I tried this , but get nil value
  puts discount_code
  render :text => discount_code
  end


What is the right way to do this?

Thanks,
Vikas

Hi Vikas Gholap

   Either

"''discount=''+$(''discount_code'').value"
   Or

"''discount=''+$F(''discount_code'')"

Thanks Sijo,

But I don''t have problem related to this.

My question is that how i access "discount" parameter value in 
controller.

using discount_value = params[:discount] gives me nil.

How can i access paramter value passed in ":with"

Thanks again,
Vikas

I think the correct is :
link_to_remote "Apply", :update => "result", :url => {
:action => "discount_code"}, :with => "discount=$
(discount_code).value"

Thanks,

but how can i pass multiple parameters through :with option in 
link_to_remote

for example

=link_to_remote "Apply", :update => "plan_discount", :url
=> { :action
=> "discount_code"},
:with=>"''discount=''+$(''discount_code'').value
&''discount2=''+$(''discount_code2'').value"

This is not working.

Where I''m doing wrong.

Hi Vikas

:with =>"''discount=''+
escape($(''discount_code'').value) +
''&discount2='' +
escape($(''discount_code2'').value)"

Hello Sijo

Thanks, but it is not working.

For only one parameter it is working fine, but not for more than one 
parameter.
There is syntax error, but i tried it various ways, failed.

Following is my link_to_remote function

=link_to_remote "Apply", :update => "plan_discount", :url
=> { :action
=> "discount_code"}, :with
=>"''discount=''+
escape($(''discount_code'').value) +
''&tariff_plan='' +
escape($(''tariff_plan_id'').value)"

HTML generated from above is

<a onclick="new Ajax.Updater(''plan_discount_result'', 
''/subscriptions/discount_code'', {asynchronous:true,
evalScripts:true,
parameters:''discount=''+
escape($(''discount_code'').value) +
''&tariff_plan='' +
escape($(''tariff_plan_id'').value) +
''&authenticity_token='' + 
encodeURIComponent(''FgSc9EashXK3rPds+Y31d0emXvwRRAQyEoWq1ksyH90='')});
return false;" href="#">Apply</a>

textfields discount_code and tariff_plan_id

"tariff_plan_id" is a redio button and "discount_code" is a
textfield

%input{:type=>''radio'',
:name=>''tariff_plan_id'',
:value=>"#{plan[''service''][''name''].downcase}_#{plan[''payment_term''][''name''].downcase}"}

=text_field_tag ''discount_code''


=link_to_remote "Apply", :update => "plan_discount", :url
=> { :action
=> "discount_code"}, :with
=>"''discount=''+
escape($(''discount_code'').value) +
''&tariff_plan=''+
escape($(''tariff_plan_id'').value)"

When I click on "Apply" link, nothing happens.

Thanks,
Vikas

Yes, by giving id to radio button it works.

But I have 5 radio_button with group "tariff_plan_id". If i give same
id
to all of them, there is problem of having same id for 5 radio buttons. 
and I think this is not correct.


- service[''all_plans''].each do |plan|
  %input{:type=>''radio'', :id => 
"tariff_plan_id_#{plan[''service''][''name''].downcase}_#{plan[''payment_term''][''name''].downcase}",
:name=>''tariff_plan_id'', 
:value=>"#{plan[''service''][''name''].downcase}_#{plan[''payment_term''][''name''].downcase}"}


here for each plan one radio button is generated.
So another problem arises that how i know that which radio button is 
selected from "tariff_plan_id" group.

if consider 5 radio buttons are there (may be increased in feature)
then I have to specify

tariff_plan_id_1
tariff_plan_id_2
tariff_plan_id_3
tariff_plan_id_4
tariff_plan_id_5

Thanks,
Vikas
