Hi all,
I have a little bit problem with my code here. basically, i want to have a drop down list, and if i select one value of the drop down list, the value of the text field that i have will change its value.
what i have done is to use observe field to dynamically update my text field. however, when i am pressing the submit button, it doesnt want to read the value of the text field. anyone knows what happen?
here is my code:
chapter controllers: def upload @chapter = Chapter.new @uploads = Book.find(:all)
def get_chapter_number @books= Book.find(:first, :conditions => ["title = ?", params["title"]]) render :layout => false end end
views for upload: <%= javascript_include_tag "prototype" %> <% form_for (:chapter, @chapter, :url=>{:action => "uploadFile"}, :html => {:multipart => true}) do |f| -%>
<label class="required">series title:</label> <select name="upload[title]" id="upload[title]"> <% @uploads.each do |upload| %> <option value="<%= upload.title %>"> <%= upload.title %> </option> <% end %> </select>
<label class="required"> chapter: </label> <div id="chapter_container"> </div>
<%= observe_field("upload [title]", :update=>"chapter_container", :url=>{:action => "get_chapter_number"}, :with => 'title', :on=>"changed") %>
<%= submit_tag 'Upload', :class => "submit" %>
views for get_chapter_number: <input type="text" id="upload_number_of_chapters" name="upload [number_of_chapters]" value= <%= @books.number_of_chapters + 1 %> size = "30" />
that code works fine.. if i select the value of the drop down list, it will dynamically update the text field. however, when i press the submit button, it doesnt read the value of the text field that being updated. any suggestion or help?
thanks in advance,
