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>
希望本文所述对大家JavaScript程序设计有所帮助。
