例如ES5中在原型上添加的方法就属于静态成员,ES6 class类引入简化了静态成员的创建,只需要在方法与访问器属性的名称前添加 static关键字即可。例如下面的代码用于区分静态方法和实例方法。 functionPersonType(name) {this.name =name; }//静态方法PersonType.create =function(name) {returnnewPersonType(name); };...

为类创建静态成员,是面向对象语言的特点,js是可以通过prototype来实现这一特点 代码语言:javascript // 用function 模拟一个类出来,同时也作为构造函数functionMyClass(){this.name="https://coder.itclan.cn";// 类的成员变量namethis.myStaticFun=myStaticFun;// 类的成员函数,把私有函数放到外头,避免重复创建...
