A simple JavaScript inheritance library for ES5 inspired by John Resig's Simple JavaScript Inheritance.
If you want to use this library in a non-ES5 environment, consider including es5-shim.
var Person = Class.extend({
init: function(isDancing){
this.dancing = isDancing;
},
dance: function(){
return this.dancing;
}
});
var Ninja = Person.extend({
init: function(){
this._super( false );
},
dance: function(){
// Call the inherited version of dance()
return this._super();
},
swingSword: function(){
return true;
}
});
var p = new Person(true);
p.dance(); // => true
var n = new Ninja();
n.dance(); // => false
n.swingSword(); // => true
// Should all be true
p instanceof Person && p instanceof Class &&
n instanceof Ninja && n instanceof Person && n instanceof Class
