11年前
jOOPL 是一个 JavaScript 面向对象框架，全称是："JavaScript Object-Oriented Programming Library".
是一个轻量级、易用的面向对象编程库，允许使用纯 JavaScript 实现高级面向对象特性，包括：
- 继承.
- 多态
- 封装
- 组合
示例代码：
// First of all, we are going to declare a namespace for the class $namespace.register("Joopl.Samples"); // Next part will be about designing the whole class Joopl.Samples.Polygon = $class.declare( // The constructor function() { // This is very recommended: if you declare a class field in the constructor, // it will hold a default value instead of undefined this.$_.args = null; }, { // Sets an object that will hold the arguments to calculate the polygon's area set_Args: function(value) { this.$_.args = value; }, // Gets an object that will hold the arguments to calculate the polygon's area get_Args: function() { return this.$_.args; }, // The method to calculate the area. Check that its body does implement nothing. // Derived classes will be the ones responsible of providing the formula to make the calculation. CalculateArea: function() { } } );
