JavaScript构建自己的对象示例

本文实例讲述了JavaScript构建自己的对象。分享给大家供大家参考，具体如下：

<script type='text/javascript'>
//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());
