js创建对象的多种方式 1. 工厂模式 function createPerson(name) { var o = new Object() 0.name = name return o } var person1 = createPerson('xwk') 缺点:创造出来的对象无法识别,因为都指向同一个原型. 2. 构造函数模式 function Person(name) { this.name = name this.getName = function() { console.log(th
JS创建对象篇 Object构造函数创建 var person = new Object(); person.name = "Tom"; person.age = 10; person.sayName = function(){ alert(this.name); } 对象字面量 var person = { name : "Tom",//注意这边是以“,"分隔,而不是”;" age : 10, sayName : function(){ ale
A module in Node.js is a logical encapsulation of code in a single unit. It's always a good programming practice to always segregate code in such a way that makes it more manageable and maintainable for future purposes. That's where modules in Node.j
1.采用直接量创建方式:系统会使用new方式自动创建对象 var o = {x:1,y:2,z:2}; 2.采用new关键字创建对象:采用构造函数创建对象 var o = new Object();//创建一个空对象,括号可省略 var x = new Object({a:1,b:3});//创建一个具有两个属性的对象 3.采用Object.create创建对象:采用原型链创建 var o = Object.create({a:1,b:3}); 4.采用Object.defineProperti
