在有些面向对象的编程语言中,我们可以通过static关键词来声明静态属性,这一点,在Javascript中可以通过“模拟”的方式实现。 1、定义静态属性 基本语法:类名.属性(静态属性)其访问时也是通过类名.属性进行访问的。 特别注意:在Javascript中,Math数学类下的所有属性和方法都是静态的。 在Javascript中,有两种属性: 对象...
JavaScript中的类 JavaScript实际上是一种弱类型语言,与C++和Java等语言不同。因此,在JavaScript中,没有强调类(class)这一概念,但实际运用中,类还是很重要的,比如写一款游戏,如果我们不停地调用函数来完成创建角色,移动角色的话,那会是什么样的呢?可能会出现非常多的重复代码,因此我们需要一个类来统一这些代码。所...
