TypeScript动态创建类的方法

首先定义一个Greeter的类

  class Greeter {      greeting: string;      constructor(message: string) {          this.greeting = message;      }      greet() {          return "Hello, " + this.greeting;      }  }

根据字符串动态创建Greeter类

  //instance creation here  var greeter = Object.create(window["Greeter"].prototype);  greeter.constructor.apply(greeter, new Array("World"));  	var button = document.createElement('button');  	button.innerText = "Say Hello";  	button.onclick = function() {  	    alert(greeter.greet());  	}  document.body.appendChild(button);
