-Forms are very well supported in Ruby on Rails. But in some cases you want to get information about a value a user has entered in a form, but without submitting the entire form. A good example of this is the sign up procedure at Yahoo. You enter your desired username, click "check availability" and you know if the name is available to you.
-
-In my case I want to add locations to my database and use geocoding to get latituden/longitude values. So, I want users to enter an address and click "check" to verify that geocoding is successful. When successful, the full address and lat/lng values are automatically filled out in the form.
-
-This article shows you how to update those text fields and most importantly, it shows how to add a text_field value as a paramater to your link_to_remote tag.
-
-This last part is easy with RJS:
-
-``` ruby
-render :update do |page|
-  page[:location_address].value = gecode.full_address
-  page[:location_lat].value = geocode.lat
-  page[:location_lng].value = geocode.lng
-end
-```
-
-But now the tricky part! How to include the value of a text_field in a link_to_remote tag?? A normal link_to_remote tag might look like this:
-
-``` ruby
-link_to_remote "Check address",
-   :url {
-      :controller => 'locations',
-      :action => 'check_address',
-      :address => @location.address
-   },
-   :method => :get
-```
-
-The problem here is that we're at the 'new' form, so @location doesn't contain anything yet. Erb isn't going to help us either because it's already rendered and cannot change something 'onClick'.
-
-You got it, JavaScript is your friend! You could now write a JS function that retrieves the value of the text_field and add it to the link_to_remote request. Well, you could. But there is an easier way!
-
-Prototype is the answer! It comes default with Rails and if you already use the javascript defaults, it's already at your diposal. If not, include prototype in your layout first:
-
-``` erb
-<%= javascript_include_tag 'prototype' %>
-```
-
-Now, we can use Form.element.getValue to get the text_field value. Since Prototype is very nice, there's a shortcut available: $F(element).
-
-The next question is how to integrate this with our link_to_remote tag. The :with paramater offers help!
-
-``` ruby
-link_to_remote "Check address",
-   :url {
-      :controller => 'locations',
-      :action => 'check_address',
-      :address => @location.address
-   },
-   :with => "'address='+encodeURIComponent($F(
-```
