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（））;</script>
