如何在基类(Angular2+)中获取派生类名?

您需要使用构造函数类的name属性。

class Base {   
    public process(value: any) {
        alert(this.constructor["name"]); // alerts 'Derived' in this example
    }
}

class Derived extends Base {
    public process(value: any) {
        super.process(value); // use super to call methods on the base class
    }
}

(new Derived).process('someValue');
