javascript - 学习 OOP Javascript，我真的很努力，但它并没有陷入困境。任何人都可以帮我解决这个问题吗？

Question

所以，我从这个开始。我想，Worker 是我的类

    function Worker(firstName, lastName, role, action) {
        this.firstName = firstName;
        this.lastName = lastName;
        this.role = role;
        this.action = action;
        Worker.random = function (name) {
            name = this.name
            let actions = this.action
            console.log(Math.floor((Math.random() * name.action)))
        }


    }

现在我想在这里用它制作一个"new"对象，

let Stanley = new Worker('Stanley', 'Hudson', 'Sales', [
    'Did I Stutter?? You and Michael drink 3.',
    'You just had a heart attack and every time Michael opens his mouth you\'re stress levels to up. Drink 4 to calm your nerves',
    'Your cheating has caught up with you. Bad Stanley. Drink 2'
])

我如何才能做到 Stanley.random() 并从 Action 数组中取回随机 Action ？我希望能够对任何字符使用 random() 函数。我真的不知道该怎么做？这是重点吧？能够一遍又一遍地使用这些方法？

我知道我很笨，如果你想告诉我，请随意，只要知道我知道就行了。任何帮助，非常感谢

您可以将函数分配给类属性以及常规数据。因此，您需要将 this.random 分配给函数，而不是 Worker.random.. 这样的事情应该可以解决问题..

function Worker(firstName, lastName, role, action) {
  this.firstName = firstName;
  this.lastName = lastName;
  this.role = role;
  this.action = action;
  this.random = function() {
    if (this.action.length > 0) {
      return this.action[Math.floor(Math.random() * this.action.length)];
    }
  };
}

let Stanley = new Worker("Stanley", "Hudson", "Sales", [
  "Did I Stutter?? You and Michael drink 3.",
  "You just had a heart attack and every time Michael opens his mouth you're stress levels to up. Drink 4 to calm your nerves",
  "Your cheating has caught up with you. Bad Stanley. Drink 2"
]);

let randomAction = Stanley.random();
console.log("Random Action From Stanley:", randomAction);
