This is a terrible China Mobile trap. Everyone must be careful. Last, the IP discount is not applicable to roaming. This is not true. I tried it. Adding 17951 during roaming is only 0.39 RMB/minute. ---------------------------- Preface: If you have a pair of guns, this article is worth reading and you are also welcome to comment.

I. Strategy ModeThe rule mode is intended for a group of algorithms,Encapsulate each algorithm into an independent class with a common interfaceSo that they can be replaced with each other. The policy mode allows the algorithm to change without affecting the client. Suppose we want to design a shopping cart CAT System for e-commerce websites selling books. The simplest case is to multiply the unit price of all goods by the quantity, but the actual situation must be more complicated than that. Fo

The rule mode is intended for a group Algorithm , Encapsulate each algorithm into an independent class with a common interface, so that they can be replaced with each other. The policy mode allows the algorithm to change without affecting the client. Suppose we want to design a shopping cart CAT System for e-commerce websites selling books. The simplest case is to multiply the unit price of all goods by the quantity, but the actual situation must be more complicated than that. For example,

, which are used to hold different data between objects Private $producerMainName;//All properties are set to private, do not allow external direct access to these properties, and then provide methods to obtain the desired values Private $producerFirstName; protected $price;//prevent outside access to this property directly, you can access the quilt class Private $discount= 0; Private $id= 0; //when an object is created, the constructor is ca

The desired effect is to achieve 90 percent or 80 percent of the total price of all items in the cart:When you click on "90 percent":When you click on "80 percent":-Ideas80 percent or 90 percent is the different implementation of the discounted interface, the key is: what conditions to decide which discount method to use?--When you click on the 80 percent or 90 percent link, put the parameters in the route, and then in the custom controller factory, d

JTable application and JTable Application A table is used in a recent project. The table looks like this: You can modify the quantity and discount, and the final price will change accordingly. The plug-in is handwritten and named as JTable. You can give jquery-loving friends a reference: The Code is as follows: /*** Created by oshine on 14-7-23. */(function ($) {var JTable = function (setting) {var defaultSetting = {header: ["service content", "qua

Define: define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it.I. Strategy Mode The purpose of the rule mode is to encapsulate each algorithm into an independent class with a common interface for mutual replacement. The policy mode allows the algorithm to change without affecting the client. Suppose we want to design a shopping cart CAT System for e-commerce websites selling books. The simplest c

When defining a base class, we want some functions in the base class to be redefined in the derived class. For example, we define a base-class record book to find out how much it costs to buy a book. In a derived class, we define a discount book, you still need to calculate the amount of money spent on the books you have bought. In this case, you need to redefine the function for calculating the amount of money. Note that the definition here is differ
