In ASP programming, classes play a good role in encapsulation. Although they are only based on objects and cannot be object-oriented in the true sense, it is very necessary to use classes well. So now let the editor analyze the classes in ASP for you in detail.
The functions of the class can be implemented purely with Sub and Function, but the class provides a more comfortable interface method. In ASP, there is no concept of "namespace". When many sub and functions are used, in order to distinguish these sub and functions, long and difficult to remember names are often used. Moreover, the interface method of Sub and Function is very rigid, but it can be greatly improved if you use classes.
Classes cannot help you improve the operation efficiency of your program, but classes can improve your development efficiency and improve your programming habits.
Since it comes to packaging, it involves good packaging and bad packaging. How to design the properties and methods of your class, that is, how to design the interface of this class, determines how much your class can assist you in development. If you don't encapsulate well, the class may not bring you much practical convenience. But if you encapsulate it well, classes can indeed bring qualitative improvements to your development.
When should you use a class? Basically, the more complex the input and output interfaces of your modular functions, the more suitable it is to encapsulate it into a class. But this is obviously not necessary, and you can also achieve it with Function and Sub. If you have already tasted the sweetness of classes, you will inevitably tend to write these modules with complex interfaces and relatively independent functions into classes.
After reading the above, the editor will analyze the categories in ASP for you in detail. If you still have some unclear things, you can find the wrong new editor at any time. For more exciting content, you can go to the wrong new technology channel.
