Low Pro is a set of extensions to the Prototype library that make it easier to implement unobtrusive DOM scripting and forms the JavaScript component of the Unobtrusive JavaScript Plugin For Rails but can be used separately. It is essentially a compilation of various tried and tested, previously published techniques adapted for use with Prototype and mainly centers around enhancing event handling and DOM manipulation.

As Prototype’s DOM manipulation is very innerHTML centred, Low Pro adds few useful methods to elements to help you navigate and manipulate the DOM in the nice clean W3C way.

Also, Low Pro aids you in creating node structures via the DOM with a Prototype version of DOM Builder. Each HTML tag has a builder function called $[tag]. You can nest these to create complex DOM structures easily.

Low Pro adds declaritive behaviours to Prototype. Event.addBehavior() allows you to specify element behaviours via CSS selectors.

These behaviours are applied as soon as the DOM is loaded and are reapplied to new elements after Ajax calls. An alternative more OO approach is to create a Behaviour ‘class’ which can be attached to elements. Each element gets it’s own instance of the behaviour class that retains it’s state throughout the life of the page. Within behaviour classes, this.element always points to the attached element.

Low Pro Prototype extension allows you to manipulate DOM scripting with ease.
