问题描述
是否可以声明一个类具有某些功能而不实现它们?
Is it possible to declare that a class has certain functions without implementing them?
我需要这个,因为我创建了一个类,然后将其传递给添加了几个函数的 js 框架.我也希望能够调用这些函数而无需重新实现它们、重定向或强制转换或其他任何东西.
I need this because I create a class that is then passed to a js framework which adds a couple of functions. I wanna be able to call those functions aswell without reimplementing them, redirecting or casting or whatsoever.
示例:
//example class
class AppComponent {
constructor() {}
}
//create class
var comp: AppComponent = new AppComponent();
//hand over to framework
fw.define("Component", comp);
//now I want to be able to call the added functions such as:
comp.setModel(/*some model*/);
推荐答案
你可以声明函数而不实现它.
You may declare the function without implementing it.
//example class
class AppComponent {
constructor() { }
setModel: () => void;
}
//create class
var comp: AppComponent = new AppComponent();
//hand over to framework
fw.define("Component", comp);
//now I want to be able to call the added functions such as:
comp.setModel(/*some model*/);
