Chúng tôi đang dần tiến tới sự phát triển của đơn vị cốt lõi của trang web bất động sản, đó là cơ sở dữ liệu, lưu giữ thông tin về tất cả những ngôi nhà để bán. Trong phần đầu tiên của chương này, một tính năng của AS2 lớp mà chúng tôi chưa thảo luận sẽ được giới thiệu: | Creating the Database Part 1 Introduction We are now approaching the development of the core unit of the real estate Web site which is the database which stores information about all of the homes for sale. In the first section of this chapter a feature of AS2 class that we have not yet discussed will be introduced the interface. The concept is the same for AS3 class files and will not be discussed further in that section. Next we will write the class files for the basic database which displays data. We will then discuss the structure of the interface. In Part 2 Chapter 14 we will add features such as saving data using the shared object dividing the displays into groups with Next and Previous buttons and displaying HTML pages for more information. We have already covered some of these applications in previous chapters but now we will put it all together into one application. So feel like a project manager and imagine that you have to oversee the whole project. You will notice that the way the movie will be set up is slightly different from previous sections. There will be hardly any MovieClips on the stage because we will add those by using a scr ipt. Furthermore all MovieClips that will be manipulated by code will be associated with a class. All clips that are static will be graphics. You are now asking me why we are doing this One reason for you to learn AS2 is to get prepared for AS3 and associating MovieClips with classes is something you should get used to now. When you prepare an AS3-based movie all MovieClips which are manipulated by code are classes. This can be very handy because we can manipulate individual MovieClips using their own classes. As you will see we will do this for some MovieClips in our AS2-based application as well. Structure of the Search Engine The main question of each project is what do we want to achieve Before we start working on individual projects we have to clarify this point. So we will now list what the user will be able to do .
