Definition

Classes are objects that contain inherits for instances. You can extend and create instances of an existing class. Classes are based on prototypal inheritance, that way, you can easily update all subclasses and instances from one of their parent class.

Methods

klass.extend([object]) -> newClass

Creates a new class that inherits from klass. Optionaly takes an object arguments that extends the newClass as owned properties.

object
  • object.mixins : array

list of classes the given class should compose with.

klass.create([args …]) -> newInstance

Creates a new instance that inherits from klass. Its arguments are passed to klass.constructor which is called if klass owns a constructor method.

instance.destroy([args …])

Removes all the internal references to instance, as in parent.instances for instance. Its arguments are passed to klass.destructor which is called if klass owns a destructor method.

instance.accessor(name) > function

Returns a function that calls instance[name] with instance as thisValue and passes its arguments to the method.

Example

var klass = require("bloody-class")
var $ = require("jquery")
 
var view = klass.extend({
  constructor : function(){
    this.element = $(this.element || document.createElement("div"))
    if(typeof this.name != "string") {
      throw new TypeError("name must be a string")
    }
    if(typeof this.initialise == "function") {
      this.initialise.apply(this, arguments)
    }
    this.initEvent()
  },
  $ : function(selector){
    return this.element.find(selector)
  },
  destructor : function(){
    this.element.off("." + this.name)
    if(typeof this.release == "function") {
      this.release.apply(this, arguments)
    }
  },
  initEvent : function(){
    if(!this.events) return
    var index = -1
    var length = this.events.length
    var thisValue = this
    while(++index < length) {
      ;(function(object){
        this.element.on(
          object.type + ("." + this.name),
          object.selector,
          function() {
            return thisValue[object.listener]
              .apply(thisValue, arguments)
          }
        )
      }).call(this, this.events[index])
    }
  }
})
 
 
var myView = view.create({
  name : "elementView",
  element : "#element",
  mixins : [events],
  events : [
    {
      type : "click",
      selector : ".js-anchor"
      listener : "navigateTo"
    }
  ],
  navigateTo : function(eventObject){
    window.scrollTo(0, $(eventObject.currentTarget).offset().top)
  }
})
