protJS

Opt-In prototype helper functions

This toolset was designed to provide the ease-of-use and legibility of prototypal methods, without actually modifying the core objects, or bloating all variables of that constructor type. It does this by providing short-hand 'wrappers' for different data types which extend JavaScript's native functionality during those chained calls.

The wrappers currently available:

• Array: A(myArray) or A([1,2,3])
• Object: O(myObj) or O({a:1, b:2})
• String: S(myStr) or S("some string")
• Node: N(myNode) or N("node selector")
• Event: E(event)
• Number/Digits: D(myNum) or D(3.5)

It also includes some standard functions used internally, but also useful outside of the wrappers:

• df(variable) - returns whether or not variable is defined.
  • df(variable,"boolean") - returns whether or not variable is of type "boolean"
  • df(variable,"boolean",true) - returns variable if it is boolean, otherwise returns true
• addEvent(element,'click',callback) - attaches the callback to a click event on the element, selecting addEventListener or attachEvent as appropriate
• getEvent(event) - returns the same event object (or window.event if invalid), but ensures that event.target is set (basically just a safe event referencer in an event handler when supporting older browsers)
