Principle Make variables shouldn't be changed stand out using all caps. Add constants as static properties to the constructor function. // constructor var Widget = function () { // implementation... }; // constants Widget.MAX_HEIGHT = 320; Widget.MAX…

访问修饰符(或者叫访问控制符)是面向对象语言的特性之一,用于对类.类成员函数.类成员变量进行访问控制.同时,访问控制符也是语法保留关键字,用于封装组件. Public, Private, Protected at Class Level 在创建类时,我们需要考虑类的作用域范围,如谁可访问该类,谁可访问该类成员变量,谁可访问该类成员函数. 换而言之,我们需要约束类成员的访问范围.一个简单的规则,类成员函数.类成员变量之间可以自由 访问不受约束,这里主要说的是外部的访问约束.在创建class的时候,…
