JavaScript build your own object example

The example in this article describes how to construct your own objects in JavaScript. Sharing it with everyone for your reference, the details are as follows:

<script type=&#39;text/javascript&#39;>
//构建一个CustomerBooking类
//构造函数
function CustomerBooking(bookingId,customerName,film,showDate){
  this.bookingId = bookingId;
  this.customerName = customerName;
  this.film = film;
  this.showDate =showDate;
}
//getBookingId方法，有点奇特
CustomerBooking.prototype.getBookingId = function(){
  return this.bookingId;
}
//setBookingId方法
CustomerBooking.prototype.setBookingId = function(bookingId){
  this.bookingId = bookingId;
}
CustomerBooking.prototype.getCustomerName = function(){
  return this.customerName;
}
CustomerBooking.prototype.setCustomerName = function(customerName){
  this.customerName = customerName;
}
CustomerBooking.prototype.getFilm = function(){
  return this.film;
}
CustomerBooking.prototype.setFilm = function(film){
  this.film = film;
}
CustomerBooking.prototype.getShowDate = function(){
  return this.showDate;
}
CustomerBooking.prototype.setShowDate = function(showDate){
  this.showDate = showDate;
}
//构建一个cineme类，属性为数组，可以保存预定信息
function cinema(){
  this.bookings = new Array();
}
//addBooking方法
cinema.prototype.addBooking = function(bookingId,customerName,film,showDate){
  this.bookings[bookingId] = new CustomerBooking(bookingId,customerName,film,showDate);
}
//getBookingsTable方法
cinema.prototype.getBookingsTable = function(){
  var booking;
  var bookingsTableHTML="<table border=1>";
  for(booking in this.bookings){
    bookingsTableHTML +="<tr><td>";
    bookingsTableHTML +=this.bookings[booking].getBookingId();
    bookingsTableHTML +="</td>";
    bookingsTableHTML +="<td>";
    bookingsTableHTML +=this.bookings[booking].getCustomerName();
    bookingsTableHTML +="</td>";
    bookingsTableHTML +="<td>";
    bookingsTableHTML +=this.bookings[booking].getFilm();
    bookingsTableHTML +="</td>";
    bookingsTableHTML +="<td>";
    bookingsTableHTML +=this.bookings[booking].getShowDate();
    bookingsTableHTML +="</td></tr>";
  }
  bookingsTableHTML +="</table>";
  return bookingsTableHTML;
}
//新建cinema对象就可以了，这里会通过addBooking自动生成customerBooking对象，
保存到cinema对象bookingFilm的属性当中，然后调用getBookingsTable方法来获取数据信息
var bookingFilm = new cinema();
bookingFilm.addBooking(123,"Jack","Love Java","1 May 2012");
bookingFilm.addBooking(123,"Jack","Love Java","1 May 2012");
bookingFilm.addBooking(122,"Jack","Love Java","1 May 2012");
bookingFilm.addBooking(121,"Jack","Love Java","1 May 2012");
bookingFilm.addBooking(120,"Jack","Love Java","1 May 2012");
bookingFilm.addBooking(119,"Jack","Love Java","1 May 2012");
document.write(bookingFilm.getBookingsTable());
