Obviously, you'll want to be a bit more sophisticated than that, but it's a
start. You can see more about the events [in the jquery-ujs wiki](https://github.com/rails/jquery-ujs/wiki/ajax).
+Another possibility is returning javascript directly from the server side on
+remote calls:
+
+```ruby
+# articles_controller
+def create
+ respond_to do |format|
+ if @article.save
+ format.html { ... }
+ format.js do
+ render js: <<-endjs
+ alert('Article saved successfully!');
+ window.location = '#{article_path(@article)}';
+ endjs
+ end
+ else
+ format.html { ... }
+ format.js do
+ render js: "alert('There are empty fields in the form!');"
+ end
+ end
+ end
+end
+```
+
+NOTE: If javascript is disabled in the user browser, `format.html { ... }`
+block should be executed as fallback.
