Get value from form using rjs, and problem with Safari

Rails
1

Hi,

I have got two forms, the first is a textarea plus a link that activates
some javascript to change the form, the second activates some javascript
on
the onchange event which changes it into a textarea form.

This works in Firefox, but not in Safari.

Also, I need the value which is selected. I’ve found an example that
gives
the parameter to the javascript, like this:

<input type=“checkbox” name=“name”

onclick="new Ajax.Request('<%= url_for(:action =>

‘update_attribute’,
:id => obj) %>’,
{parameters:‘name=’+this.name+’&value=’+this.checked})"/>

How do I get the value which is selected when the onchange event occurs
using RJS?

View:

<%= javascript_include_tag :defaults %>

Test for Safari

%= form_tag :action => ‘do_something’, :id => @survey %>

<%= q_item(1, 1)%>

      <%= text_area("row1", "col2", { :cols => "20", :rows => "3" })

%>

               <%= link_to_remote("change",

    :url => { :action => :change_back_div,

:id => “form1_2” },

                                  :id => "change") %>

      </div>

<%= submit_tag ‘Send’ %>

<%= end_form_tag %>

helper:

module AdminHelper

def q_item(row, col)

        return select("row"+row.to_s, "col"+col.to_s, %w{ Text

Rating3
Rating4 ListItem GrantAccess},

              {:include_blank => true},

                            { :onchange => remote_function(

                                                              :url

=> {
:action => :change_div,

:id => “form”+row.to_s + “_” + col.to_s } ) } )

      end

def to_question_item_form

id = params[:id]

remote_function( :url => { :action => :change_div,

                           :id => id } )

end

admin_controller:

def change_div

pos = args_id(params[:id])

html_options = { :class => "change" }

render :update do |page|

  page[pos[:form]].replace( tag("div", "id" => pos[:form]) <<

    text_area(pos[:row], pos[:col], {:cols => 20, :rows => 3}) <<

    tag("div", "class" => "change") <<

    link_to_function("change",

      remote_function( :url => { :action => :change_back_div,

                                 :id => pos[:form] }),

      html_options))

  page.visual_effect :highlight, pos[:form], :duration => 2

end

end

def change_back_div

pos = args_id(params[:id])

render :update do |page|

        page[pos[:form]].replace( tag("div", "id" => pos[:form]) <<

        select(pos[:row], pos[:col], %w{ Text Rating3 Rating4

ListItem
GrantAccess},

                            { :include_blank => true },

                            { :onchange => to_question_item_form }

))

  page.visual_effect :highlight , pos[:form], :duration => 2

end

end

Thanks,

Jens
