My colleague Luke Burton has posted a wonderful RJS Tutorial. [Read more] for a short list of the new things it taught me. ? You can insert RJS calls in RHTML documents, not just RJS documents ? The relevant documentation is ActionView::Helpers::PrototypeHelper and ActionView::Helpers::PrototypeHelper::JavaScriptGenerator::GeneratorMethods ? RJS handles (most) error catching for me ? You can... Continue Reading →
