Getting value of form using Ajax (and problems with Safari)


#1

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:

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

Thanks,

View:
Code:

<%= 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") %>

<%= submit_tag ‘Send’ %>
<%= end_form_tag %>

helper:
Code:

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:
Code:
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
