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：
<scripttype='text/javascript'>
//构建一个CustomerBooking类
//构造函数
functionCustomerBooking(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(){
returnthis.bookingId;
}
//setBookingId方法
CustomerBooking.prototype.setBookingId=function(bookingId){
this.bookingId=bookingId;
}
CustomerBooking.prototype.getCustomerName=function(){
returnthis.customerName;
}
CustomerBooking.prototype.setCustomerName=function(customerName){
this.customerName=customerName;
}
CustomerBooking.prototype.getFilm=function(){
returnthis.film;
}
CustomerBooking.prototype.setFilm=function(film){
this.film=film;
}
CustomerBooking.prototype.getShowDate=function(){
returnthis.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
functioncinema(){
this.bookings=newArray();
}
//addBooking方法
cinema.prototype.addBooking=function(bookingId,customerName,film,showDate){
this.bookings[bookingId]=newCustomerBooking(bookingId,customerName,film,showDate);
}
//getBookingsTable方法
cinema.prototype.getBookingsTable=function(){
varbooking;
varbookingsTableHTML="<tableborder=1>";
for(bookinginthis.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>";
returnbookingsTableHTML;
}
//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
varbookingFilm=newcinema();
bookingFilm.addBooking(123,"Jack","LoveJava","1May2012");
bookingFilm.addBooking(123,"Jack","LoveJava","1May2012");
bookingFilm.addBooking(122,"Jack","LoveJava","1May2012");
bookingFilm.addBooking(121,"Jack","LoveJava","1May2012");
bookingFilm.addBooking(120,"Jack","LoveJava","1May2012");
bookingFilm.addBooking(119,"Jack","LoveJava","1May2012");
document.write(bookingFilm.getBookingsTable());
