hi all,,
i got a little problem here.
with my code below, what i am trying to do is to select the value from
drop down list, and then updating the value of the text field.
However, after updating the value of the text field, the value of the
text field
is not submitted by pressing the submit button.
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" />
appreciate any help.. thanks,
prawira
