Some time ago, I made a topic about JavaScript and OOP in the team. I finally remember to bring it here and share it! 1. Data Structure The data in Javascript is concise. Simple data only includes undefined, null, Boolean, number, and string types, but there is only one type of complex data, that is, object. this is like the Chinese classical simple materialism, which classifies the most basic elements of the world as gold, wood, and fire. Other comp

Where is my oop wrong? Is the problem of static variables? Class db{public $conn; private static $h = "localhost"; private static $u = "root"; private static $p = "123123"; private static $d = "Air";function __construct () {$this->conn=mysqli_connect (self:: $h, Self:: $u, Self:: $p, Self:: $d);$this->conn->query (' SET NAMES UTF8 ');Mysqli_query ($this->conn, ' SET NAMES UTF8 ');} Public Function GetOne ($sql, $resultType =mysql_assoc

Doophp means do oop php. The author is not a foreigner, but a Chinese cool man. I love this framework. Before that, I like codeigniter. But after meeting doophp, I immediately changed my mind !! I am really a flowery person. Doophp features only one word, fast. There is no second word. The development speed is fast. More importantly, doophp is the fastest running speed in the hundreds of complicated frameworks in the PHP world. It can reach 1/3 of cod

AOP-Aspect Oriented Programming: Aspect-oriented programming. It is essentially different from object-oriented programming. However, the two are still very different in their design ideas. AOP focuses on a certain step or stage of the business processing process, and emphasizes reducing the coupling between modules to make the code more portable. Object-Oriented Programming encapsulates methods and attributes of entities extracted from business analysis. It can also be said that AOP is oriente

a method body, which is similar to an abstract class. The difference between them is that an interface cannot declare any method that has a method body, and they use a different syntax. To force the uncover rule to be added to a class, we need to use the Implements keyword instead of the extends keyword.In some cases we need to determine whether a class is a type of a particular class, or whether a particular interface is implemented. Instanceof is divided into fit to complete this task. Instan

Do not say his concept, if you want to build a computer classroom, first to have a room, the room to have n computers, there are n tables, n chairs, white boards, projectors and so on, these are what, just now we said, this is the object, can see the entity, Can say this computer classroom unit is this one entity object, they together compose this computer classroom, then we are the procedure, this and object-oriented have what relation? Develop a system program and build a computer classroom. S

whether it is final. The 7) class member method is only intended for internal invocation of the class and must be private. The 8) class member method is only exposed to the inheriting class, and is limited to protected. description: Any class, method, parameter, variable, strict access to the scope. A wide range of access is not conducive to module decoupling. Think test: If it is a private method, you want to delete it, but a public service method, or a The scope of the variable

method is called by the object's garbage collector when the garbage collector determines that there are no more references to the object.The order in which the program executes in the inheritance:Parent class static code block > Subclass Static code block > Parent code block > Parent class construction Method > Subclass code block > Subclass Construction MethodNew subclass, the constructor of the parent class is called first, the parent class object is created, and then the child class instance

method, all the methods in the object instance created by the new person () are modified, because the same prototype method run is common in all instances. This is an application of the prototype. This is some understanding of creating objects. Written for a long time. I don't know if there are any mistakes. If there are mistakes, you are welcome to greatly advise. Next time you write something about object-oriented inheritance. The above is small set for everyone to the JS

is an array of classes, by determining the length of the passed parameter can be accessed to the value of the parameter list. Polymorphic definition: means that objects of different classes are allowed to respond to the same message. That is, the same message can be used in a variety of different ways depending on the sending object. The white point is that a parent class is inherited by multiple subclasses, and then multiple subclasses can add their different properties and methods. functio
