Question

下面的 Javascript 代碼輸出： Employee {#name: "sheila", #gender: "female", #manager: Employee, #job: Job}

如何修復它以使其輸出：Employee {#name：“sheila”，#gender：“female”，#manager：“pierre”，#job：“software Engineer”}

不知道是不是吊裝問題。 我要修復哪些行，以便#manager 是“pierre”而#job 是“軟件工程師”？

class Person{                   
    #name;              
    #gender;                

    constructor(name, gender) {             
        this.#name = name;          
        this.#gender = gender;          
    };              
                    
    setName(name) {             
        this.#name = name;          
    };              
                    
    getName() {             
        return this.#name;

        this.#title = title;            
    };              
}                   
                    
const softwareEngineer = new Job("software engineer");

const pierre = new Employee("pierre", "male");                  
                    
const sheila = new Employee("sheila", "female", keith, softwareEngineer);                   
                    
sheila.setManager(pierre);                  
console.log(sheila);

問題是您打印 Object 的類型而不是值。 您需要一個 toString function 用於 Job 和 Manager 來打印值而不是類型，請參閱https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/toString
