Class.js: JavaScript Inheritance
-by Sujeet sujeetkv90@gmail.com
Usage Example:
var BaseClass = createClass({ name: '', url: '', /* class constructor */ _init: function (name, url) { if (name) { this.name = name; } if (url) { this.url = url; } }, getInfo: function () { return this.name + '- ' + this.url; } }); var ChildClass = BaseClass.extend({ /* class constructor */ _init: function (name, url) { this._super(name, url); /* call overridden method of parent class */ }, alertInfo: function (url) { alert(this.getInfo()); } }); var baseClassObj = new BaseClass('Sujeet', 'https://github.com/sujeetkv'); var childClassObj = new ChildClass('Sujeet', 'https://github.com/sujeetkv');Private class members can also be defined as:
var BaseClass = createClass((function () { /* private members */ var delim = ': '; /* public members */ return { name: '', url: '', _init: function (name, url) { if (name) { this.name = name; } if (url) { this.url = url; } }, getInfo: function () { return this.name + delim + this.url; } }; })()); var ChildClass = BaseClass.extend((function () { /* private members */ var log = function (val) { console.log(val); }; /* public members */ return { _init: function (name, url) { this._super(name, url); }, alertInfo: function () { alert(this.getInfo()); log(this.getInfo()); } }; })());
