javascript - 在 javascript 中创建一个带有方法的类

Question

我已经为此工作了好几天，但到目前为止还没有成功。每次我运行这段代码时，我都会被告知它应该是 true (或 false)，具体取决于我如何执行该函数。

function ClassTwo(name, pw, mail){
  // Exercise Two: Now that you have created your own class, 
  // you will create a class with a method on it.
  // In this class create 4 properties: username, password, email, and checkPassword.
  // Set the value of username to name,
  // Set the value of password to pw,
  // Set the value of email to mail
  // Set the value of checkPassword to a function. 
  // The checkPassword function takes a string as it's only argument.
  // Using the 'this' keyword check to see if the password on the class is the same as 
  // the string being passed in as the parameter. Return true or false.

  this.username = name,
  this.password = pw,
  this.email = mail
  this.checkPassword = function checkPassword() {
    return this.password 
  }

  }

Answer 1

您缺少 checkPassword 函数的 tested_pw 参数

function ClassTwo(name, pw, mail){
  // Exercise Two: Now that you have created your own class, 
  // you will create a class with a method on it.
  // In this class create 4 properties: username, password, email, and checkPassword.
  // Set the value of username to name,
  // Set the value of password to pw,
  // Set the value of email to mail
  // Set the value of checkPassword to a function. 
  // The checkPassword function takes a string as it's only argument.
  // Using the 'this' keyword check to see if the password on the class is the same as 
  // the string being passed in as the parameter. Return true or false.

  this.username = name,
  this.password = pw,
  this.email = mail
  this.checkPassword = function checkPassword(tested_pw) {
    return this.password === tested_pw
  }

  }
