Hi!
I want to do a functionality of wordcount. I thought of using observers
for doing that. I attached an observer to the textarea and set the polling
time as 1 second. Then in the controller i wrote the method called counter
which will take the raw_post and will count the words using length
or something like that
But my problem is in the observer it is not doing the updations.
Here is my observer code:
<%= observe_field (:value,
:frequency=>0.5,
:update=>''count'',
:url=>{:action=>:counter}) %>
What could be the problem. Plz help.
Thnx and Regards,
Swanand

After if you like to control the text_area content on server side here is a way to do it.> I attached an observer to the textarea and set > the polling time as 1 second.

In your layout you can have : <head> ... <%= javascript_include_tag :defaults %> ... </head> once this is done, here is an working example of controller, view: Controller: class ItemsController < ApplicationController def index @item = Item.new end # ... def counter render :text => ''<p id="count">''+params[:name].length.to_s+''</p>'' end end View: <p id="count">0</p> <% form_for :item, :url => {:action => :create} do |f| %> <%= f.text_area :name %> <%= observe_field (:item_name, :frequency => 0.5, :update => ''count'', :with => ''name'', :url=>{:action=>:counter}) %> <% end %> Hope this help ;-) -- Sébastien Grosjean - ZenCocoon seb.box.re zencocoon.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
