Customer Experience first: Use wireframes and prototype tools to create ideal products and prototype products
Introduction:The concept of interaction is difficult to describe in a language. How can we fully communicate and test an abstract idea? A prototype tool can answer this question.
Prototype is a companion on the

In one example, there are two roads:
function handler(greet){ console.log(greet,this.name); }var obj = { name : 'xesam' }
1. Use call or apply to change the handler's scope, handler. Call (OBJ, 'Hello'). In this case, another function is required to wrap it.
2. Change handler to a met
Class Prototype. js learning Prototype. as a successful open-source framework of javascript, js encapsulates a lot of useful functions. Although the official website does not provide any documentation, a lot of related documents are found on google, however, I still encountered some problems in the process of learning and using it. I hope that some familiar friends can give more advice on
varProto =""; function person (name, age, job) { This. Name =name; This. Age =Age ; This. Job =job; if(typeof This. sayname! ='function') { //You cannot create a prototype object with literal literals here .//Person.prototype.sayname = function () {//console.log ("name =" + THIS.name); // };Proto = Person.prototype;//prototype object without literal rewriting//If you use literals to create
A simple introduction to JavaScript's prototype prototype:Prototype prototype is a particularly important concept of JavaScript, belongs to have to master, if there is no good grasp, further use or learn JS Basic is impossible to achieve things, and this concept is a little difficult, may be the first contact with a friend is a bit difficult, The following is a brief introduction to the usage of the
Inheritance in JavaScript is accomplished through a prototype chain (prototype chain): There is another object inside each object that exists as its prototype, and the object inherits the property from the prototype. For each object, you can access its prototype object in th
Combining the constructor pattern with the prototype pattern
Constructor patterns are used to define instance properties, which are used to define methods and shared properties.
The most common way to create custom types is by combining the constructor pattern with the prototype pattern.1. Create an Object//combination using constructor mode and prototype
deep understanding of JavaScript prototype chain
In JavaScript and prototype chain is a very magical thing, for most people is also the most difficult to understand the part of mastering the prototype and prototype chain is the essence of JavaScript is an important link. Today I share my understanding of JavaScript pr
Each function created in JavaScript has a prototype (prototype) attribute, which is a pointer to an object that is used to contain properties and methods that can be shared by all instances of a particular type. If the literal meaning is understood, then prototype is the prototype object of the object instance created
PHP design pattern prototype mode, design pattern prototype
Prototype patterns are similar to engineering patterns, and are used to create objects.
Unlike the implementation of the engineering pattern, the prototype pattern is to create a good one prototype object and then
Primary roles in prototype mode
Abstract prototype (Prototype) role: Declaring a clone of its own interfaceSpecific prototype (concrete Prototype) role: Implement a clone of your own operation
When a class is mostly the same and only partially different, if you need a large
In JavaScript, inheritance is a wonderful way to implement interface inheritance, and can only rely on prototype inheritance.
Prototype chaina prototype is an object, and an instance created through a constructor has a pointer to the prototype's properties and methods. In this way, the instance object takes the property method of the constructor and the property
This article mainly introduces the basic explanation of object-oriented JS, such as the factory mode, constructor mode, prototype mode, hybrid mode, and dynamic prototype. If you need it, What Is Object-Oriented? Object-oriented is an idea! (Nonsense ).
Object-oriented can regard all key modules in the program as objects, and the module has attributes and methods. In this way, if we encapsulate some attrib
The difference between javascript prototype modification and rewriting (overwrite) Is that javascript prototype
Each JavaScript function has the prototype attribute (the javascript Object does not have this attribute). This attribute references an object, which is a prototype object. Javascript allows us to modify this

Prototype design is getting more and more attention, and its benefits do not need to be described here. From mobile Internet to traditional internet, prototype design will be involved.

Creating object objects directlyvar New Object (); var = {};stu.name= "Zhangsan"="stu"function() { alert ( "My name Zhang San"); }You can also use the Stu as a module, the module has a number of objects, the following example for a simple shopping cart system module!Shoppingcar.carinfo = function (obj) {Shoppingcar.carinfo . Carnumber = Obj.carnumber;.....}//Shopping Cart ObjectShoppingcar.orderinfo = function (obj) {Shoppongcar.orderinfo. ordernumber = obj.ordernumber;...}//Order ObjectCall
