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()); </script>
