ERPrototaculous

Introduction

ERPrototaculous was developed to provide the ajax functionality in ERDivaLook.

What is ERPrototaculous?

Features include:

• 'Organic' support for Prototype and Scriptaculous in WebObjects.
• No custom Prototype extensions
• A set of widgets in the Prototype + Scriptaculous family.
• Use of Unobtrusive Javascript.
• Virtually stateless ajax responses

Unobtrusive Javascript in ERPrototaculous

Unobtrusive javascript is used in contrast to on-demand style of ajax programming.
By including Javascript as well as CSS globally in the page wrapper, CSS and/or Javascript doesn't have to load inside ajax requests.

The result is faster and more reliable ajax in WebObjects applications.

Prototype + Scriptaculous Widgets

• Accordion
• LightWindow
• ModalBox
• CalendarDateSelect
• FileUpload

Forms in ERPrototaculous

Differences from using forms in WebObjects. i.e WOForm:

• All form controls must be named. This includes text fields, selects and buttons.
  (WebObjects dynamically assigned names are not compatible with ERPrototaculous).
• All forms in an ERPrototaculous app are instances of AjaxUpdaterForm.
• Form submits can be the form of a:
  • Static <button>
  • WOSubmitButton (if the result is to update whole page/app.
  • AjaxUpdaterButton (to update a container). Or
  • AjaxRequestButton (for a background ajax request)
