而是要用类名来调用:CLASSNAME.STATIC_METHOD_NAME() ,或者用构造函数的属性来调用该方法: this.constructor.STATIC_METHOD_NAME(). class StaticMethodCall { constructor() { console.log(StaticMethodCall.staticMethod()); // 'static method has been called.' console.log(this.constructor.staticMethod()); /...
在ES6中,我们只需通过class extends super constructor 即可比较方便的完成原来使用JS比较难理解的实现,我们可以通过babel的解析器,来看看babel是怎么把这些语法糖转成JS的实现的。具体代码可以参考 "use strict"; var _createClass = function () { function defineProperties(target, props) { for (var i = 0; ...
秉着这个歪门邪道的思想,我把这个功能封装到jpp.js这个库件中,库件的github地址例如以下: https://github.com/yuehaowang/jpp.js 当然这个库件不限于创建一个类。还能够实现函数的重载等。眼下库件还处于开发阶段,欢迎各位提交建议。 使用jpp.js创建一个类 varPeople = jpp.class({ extends :null,private: {...
classPoint{public:voidinit(){output();}staticvoidoutput(){}};voidmain(){Pointpt;Pt.init();pt.output();} 编译通过。 结论4:类的非静态成员函数可以调用用静态成员函数,但反之不能。 使用类的静态成员变量。 #include<stdio.h>classPoint{public:Point(){m_nPointCount++;}~Point(){m_nPointCount--...
这里可以举一个简单的例子：classShape{privateStringname;publicShape(Stringname){this.name=name;}...
类顾名思义,就是一类事物、或者叫做实例,它用来描述具有共同特征的一类事物。我们在python中声明类的关键词是class,类还有功能和属性,属性就是这类事物的特征,而功能就是它能做什么,也是就是方法或者函数。在python中,一切事物都是对象,而对象是基于类创建的。
