return New F ();}He is an encapsulation of class inheritance, in fact, the transition object is equivalent to the subclass in the class inheritance, but in the prototype as a transitional object appears, in order to create to return the new instantiated object.Of course, if you feel the need to cache the F transition, you don't have to create a new transition class F each time, and then the Object.create (

the interaction between the objects, the whole class can function normally. The results of the entire object-oriented analysis design are very close to our real world and are naturally easier to understand and implement. The teacher is shown in Object 6-2.Figure 6-2 using

prototype methods are added to the sub-class.Instance1.colors.push (' black '); Console.log (instance1.colors); // [' Red ', ' blue ', ' green ', ' black '] // [' Red ', ' blue ', ' green ']instance1.getname (); // CSSbook instance2.gettime (); // -Note: A subclass that wants to add a prototype method must pass a prototype object, one way to add it through the form of a point syntax, or it will be directly assigned to an

During the interview, you are always asked, what is your understanding of JavaScript object-oriented?Object-Oriented programming (Object-oriented Programming,oop) is a programming paradigm. It speaks of objects as the basic unit o

Process oriented:The process-oriented development approach is an abstraction of the underlying structure of the computer, which clearly divides the contents of the program into two parts: data and manipulating data. The core problem of this programming method is the development and optimization of data structure and algorithm;Object-oriented:Object-oriented is th

underlying modules, both of which are dependent on abstraction. Depending on the abstraction, it is programming the interface, not programming the implementation.Dependencies are bound to exist between classes and classes, modules, and modules. When there is a tight coupling between the two modules, the best way is to separate the interface and implementation: To define an abstract interface between dependencies so that the high-level module calls the interface, and the underlying module to imp

project, the organization defines The name of the class, you need to follow certain rules, preferably with the class name as the center, or you can add a uniform prefix or suffix shape into filenames, such as xxx_classname.php, classname_xxx.php, and classname.php, and so on. This example attempts to load the MyClass1 and MyClass2 classes from the myclass1.php and myclass2.php files, respectively Code Snippets Copy the Code code as follows: function __autoload ($classname) {Require_once $c

1, structured analysis methodThe structure method is mainly used to analyze the function of the system, and it is a kind of analytic method that divides the function level directly according to the data stream; The basic feature of structured methods is to use graphical symbols whenever possible when expressing problems, even if non-computer professionals are also easy to understand, design data flow chart
