Hi All,
I have a problem while updating select list using ajax and then submit
it.
what i have done is to change the drop down of a city when i changed
the state.but when i am submitting the form i am not able to get the
value of city.
Following is my code for the same.
edit.html.erb
<% form_for :user_info , :url=>{:controller=>"users",
:action=>"update_contact_details",:id=>params[:id] } do |f| %>
<% @state= UsaCity.find_by_sql('select DISTINCT state from
usa_cities') %>
<tr>
<td >State</td>
<td> <%= select_tag 'user_info[state]',
options_from_collection_for_select(@state, :state, :state,
@user_info.state) %><div id="user_sate_loading"
style="display:none"><img src="/images/loading.gif"></div>
<br><span id="stateError" class="error"></span>
<%= observe_field :user_info_state, :url
=>{:controller=>"logins",:action =>'select_city', :id=>'1'}, :update=>
'city' , :with => "'
state='+document.getElementById('user_info_state').value+'&type=contact_details'",
:on=>'click' %>
</td>
</tr>
<tr id="city">
<td >City</td>
<td><%= collection_select :user_info, :city, @cities ||
Array.new, :city, :city, :prompt=>true %><br><span id="cityError"
class="error"></span></td>
</tr>
<% end %>
controller method
def edit_city
@cities = UsaCity.find(:all, :conditions=>["state=?",
params[:state]])
@type = params[:type]
render :update do |page|
page.replace_html 'city', :partial => 'logins/select_city',
:object=>[...@cities, @type], :layout => false
end
end
_select_city.html.erb
<td>City1345</td>
<td><%= collection_select :user_info, :city, @cities || Array.new,
:city, :city, :prompt=>true %><br><span id="cityError"
class="error"></span></td>
