一、javascript的对象创建的方法

javascript可以直接创建对象，只须用 {}：

let javascriptobject = {};let testarray = [1, 2, 3, 4];javascriptobject.array = testarray;console.log(javascriptobject); /// {array: [1,2,3,4]}/预算业务管理制度javascriptobject.title = "algorithms";console.log(javascriptobject); // { arr努力前行ay: [ 1, 2, 3, 4 ], title: 'algorithms' }

二、原型继承prototypal-inheritance

创建的方式也简单：

function exampleclass() {  this.name = "javascript";  this.sayname = function () {    console.log(this.name);  };} ///new object/var example1 = new exampleclass();example1.sayname(); ///"javascript"/

也可以用添加原型的方式：

function exampleclass(){this.array = [1,2,3,4,5];this.n托克维尔ame = "javascript";}///new object/var example1 = new exampleclass();exampleclass.prototype.sayname = function() {console.log(this.name);}example1.sayname(); ///"javascript"/

三、构造器与变量

建设构造器和变量：

function exampleclass(name, size){this.name = name;this.size = size;}var example = new exampleclass("public",5);console.log(example); /// {name:"public", size: 5}//// accessing public variables/console.log(example.name); /// "public"/cocheck过去式nsole.log(example.size); /// 5/

也可以仿制一个privat-property.

function exa先天下之忧而忧后天下之乐而乐作文mpleclass(name, size) {var privatename = name;var privatesize = size;this.getname = function() {return privatename;}this.tname = function(name) {privatename = name;}this.getsize = function() {return privatesize;}this.tsize = function(size) {privatesize = size;}} var example = new exampleclass("sammie",3);example.tsize(12);console.log(example.privatename); /// undefined/console.log(example.getname()); /// "sammie"/console.log(example.size); /// undefined/console.log(example.getsize()); /// 3/
