封装:
var Greeter = (function () { function Greeter(message) { this.greeting = message; } Greeter.prototype.greet = function () { return "Hello, " + this.greeting; }; return Greeter; })(); var greeter = new Greeter("world"); var button = document.createElement(‘button‘); button.textContent = "Say Hello"; button.onclick = function () { alert(greeter.greet()); }; document.body.appendChild(button);
继承:
var __extends = this.__extends || function (d, b) { for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p]; function __() { this.constructor = d; } __.prototype = b.prototype; d.prototype = new __(); }; var Animal = (function () { function Animal(name) { this.name = name; } Animal.prototype.move = function (meters) { alert(this.name + " moved " + meters + "m."); }; return Animal; })(); var Snake = (function (_super) { __extends(Snake, _super); function Snake(name) { _super.call(this, name); } Snake.prototype.move = function () { alert("Slithering..."); _super.prototype.move.call(this, 5); }; return Snake; })(Animal); var Horse = (function (_super) { __extends(Horse, _super); function Horse(name) { _super.call(this, name); } Horse.prototype.move = function () { alert("Galloping..."); _super.prototype.move.call(this, 45); }; return Horse; })(Animal); var sam = new Snake("Sammy the Python"); var tom = new Horse("Tommy the Palomino"); sam.move(); tom.move(34);
