Question

有人可以帮我创建一个包含所有属性的新对象并插入phonebook数组吗？

var phonebook = [
  {
    firstName: "John",
    lastName: "Doe",
    phoneNumber: "000/111-111",
    address: ['street', '1', 'city', '00000']
  },
  {
    firstName: "John1",
    lastName: "Doe1",
    phoneNumber: "000/111-111",
    address: ['street', '2', 'city', '00000']
  },

     //add new one here;
  ];

phonebook.addNewContact = function(fname, lname, phonenum, address){
    this.firstName = fname; 
    this.lastName =  lname;
    this.phoneNumber = phonenum;
    this.address= address;
}

Answer 1

你可以这样做，基本上只是调用你创建的方法，但我建议你使用一个构造函数：

var phonebook = [
  {
    firstName: "John",
    lastName: "Doe",
    phoneNumber: "000/111-111",
    address: ['street', '1', 'city', '00000']
  },
  {
    firstName: "John1",
    lastName: "Doe1",
    phoneNumber: "000/111-111",
    address: ['street', '2', 'city', '00000']
  },

     //add new one here;
  ];

phonebook.addNewContact = function(fname, lname, phonenum, address){
    this.firstName = fname; 
    this.lastName =  lname;
    this.phoneNumber = phonenum;
    this.address= address;
}


var newperson = new phonebook.addNewContact('john', 'doe', '000/111-111', ['street', '3', 'city', '00000']);

您可以使用push功能实现此目的：

例如：

var phonebook = [
  {
    firstName: "John",
    lastName: "Doe",
    phoneNumber: "000/111-111",
    address: ['street', '1', 'city', '00000']
  },
  {
    firstName: "John1",
    lastName: "Doe1",
    phoneNumber: "000/111-111",
    address: ['street', '2', 'city', '00000']
  }
];

function addNew(fname, lname, phonenum, address){
    phonebook.push({
        firstName: fname,
        lastName: lname,
        phoneNumber: phonenum,
        address: address
    });
}

看起来您正在尝试添加到电话簿阵列，如果这是您想要的，那么您可以这样做：

＆＃13;

var phonebook = [
  {
    firstName: "John",
    lastName: "Doe",
    phoneNumber: "000/111-111",
    address: ['street', '1', 'city', '00000']
  },
  {
    firstName: "John1",
    lastName: "Doe1",
    phoneNumber: "000/111-111",
    address: ['street', '2', 'city', '00000']
  }
];

var addNewContact = function(fname, lname, phonenum, address){
  phonebook.push({
    firstName: fname,
    lastName:  lname,
    phoneNumber: phonenum,
    address: address
  });
};

addNewContact('Jamie', 'Bonnett', '000/111-111', ['street', '0', 'city', '00000']);

document.write('<pre>' + JSON.stringify(phonebook) + '</pre>');
