Question

我想在我的对象中添加以下方法：

＆＃34;你好 - 这个方法在控制台上记录字符串＆＃34;你好，我的名字是＆＃34; 其次是演员的名字。＆＃34;

有人可以帮我找到这个代码的错误吗？：

ButtonsModule

提前非常感谢你;）

Answer 1

您可能是初学者:)您正在将对象文字符号与构造函数混合使用。正确版本的构造函数在

之下

SimpleEmail mail = new SimpleEmail();
mail.setHostName(ConfigFactory.load().getString("mail.hostname"));
mail.setSmtpPort(ConfigFactory.load().getInt("mail.port"));
mail.setAuthenticator(new DefaultAuthenticator(ConfigFactory.load().getString("mail.username"), ConfigFactory.load().getString("mail.password")));
mail.setDebug(true);
mail.setMsg("Test");
mail.setTLS(true);
mail.setFrom("emailhere");
mail.addTo(email);
mail.setSubject("Activate your email");
mail.setMsg("message");
mail.send();

hello

循环播放演员并调用this.hello=function(){ //Rest of code }方法

hello

Answer 3

首先定义你的函数，如

function sayHello (firstName, lastName, age, numOscars) {
      console.log("Hello my name is ", firstName," ", lastName, "I am", age, "years old, and I have ", numOscars, " Oscar(s).");
}

像这样创建你的actor数组，你可以添加更多的对象。

var actors = [{firstName: "Leonardo", lastName: "DiCaprio", age: "42", numOscars: 1}, {firstName: "example", lastName: "something", age: "12", numOscars: 0}];

您可以单独调用您的函数，如：

var leonardo = actors[0]
sayHello(leonardo.firstName, leonardo.lastName, leonardo.age, leonardo.numOscars);

或使用forEach：

actors.forEach(function(actor) {
   sayHello(actor.firstName, actor.lastName, actor.age, actor.numOscars);
   console.log('\n');
}

Answer 4

function Person(firstName, lastName, age, numOscars) {
  this.firstName = firstName;
  this.lastName = lastName;
  this.age = age;
  this.numOscars = numOscars;
}

  // If hello function is added to Person functions prototype
  // then each time a new Person object is created, 
  // hello function gets inherited rather than creating a new hello function
  Person.prototype.hello = function greeting() {
      // here firstName always refer to the specific object to which belongs
      console.log("Hello, my name is " + this.firstName);
  }

// instead of new Array()
// Use short hand form of Array declaration also called Array literal notation
var actors =[];


// create a new person object and add it to actors array
actors.push(new Person("Leonardo", "DiCaprio", 41, 1));
actors.push(new Person("Jennifer", "Lawrence", 25, 1));
actors.push(new Person("Samuel L."," Jackson", 67, false));
actors.push(new Person("Meryl", "Streep", 66, 3));
actors.push(new Person("John", "Cho", 43, false));

// loop through each of actors array members and call 
// hello function
actors.forEach(function(actor){
  actor.hello();
});
