object oriented javascript es6

Then, prototype can be used to dynamically enhance the object, then some JS primitive class, do not provide the function we want, we can use prototype to enhance it.Here are some specific cases, I hope you can extrapolate:Tail to Empty string.prototype.trim=function () {return this.replace (/^\s+|\s+$/igm, ');}; Alert ("' abc ' length = = =" + ' ABC ');//measure the length of the empty after the alert ("' ABC ' to empty after the length =

Recently, I was looking at the JavaScript advanced programming design (the third edition). The object-oriented chapter has more than 20 pages, and I went back and forth for three or five times. The results of each reading were different. The first time I went over it, I was confused, as a result, when I went to bed at night, I found a lot of problems and I couldn

This time we delve into JavaScript object-oriented technology, and before we learn, we need to explain some of the object-oriented terminology. This is the common denominator that all face object language has. There are several

console.info (p2 instanceof Person); // displayed on the console: true In addition, we can also use the constructor keyword to check whether the object's constructor is of the Person type: Console.info (p1.constructor = Person); // displayed on the console: true console.info (p2.constructor = Person); // displayed on the console: true You can also print out the constructors p1 and p2 for comparison: console.info(p1.constructor);console.info(p2.constructor); The problem caused by using the cons

Today's JavaScript is a great way to rely on a variety of applications that are deeply dependent on the day. Web programmers have become accustomed to using a variety of good JavaScript frameworks to quickly develop WEB applications, ignoring the learning and understanding of native JavaScript. So, often the case is that many of the programmers who have done for

JavaScript is widely used today, and various applications depend on it daily. Web programmers have gradually become accustomed to using a variety of excellent JavaScript frameworks to quickly develop Web applications, thus ignoring the learning and in-depth understanding of native JavaScript. Therefore, it is often the case that many programmers who have develope

This article mainly introduces js object-oriented programming. If you are interested, you can refer to this article because JavaScript is based on prototype and does not have the concept of classes (ES6 is available, this will not be discussed for the moment). We can access all objects and truly achieve that everything

1. The object Object is one of the basic concepts of object-oriented programming, just look at the name and know it. In our familiar object-oriented language, such as Java or C + +, there are similar

() {} person. Prototype. Name = "Nicolas" ; Proson. Prototype. Age = 29 ; Person. Prototype. sayname = Function () {Alert ( This . Name );} VaR Person1 = New Person (); person1.sayname (); // "Nicolas" VaR Person2 = New Person (); person2.sayname (); // "Nicolas" Alert (person1.sayname = Person2.sayname ); // True We add the sayname () method and all attributes directly to the prototype attribute of person, and the constructor becomes an empty function. Even so, we can still call

The method receives two parameters: the object that contains the property and the name of the property whose descriptor is to be read, and the return value is an object.[note] You c
