jOOPL- JavaScript 面向对象框架
JavaScript 常用JavaScript包
共0Star
详细介绍
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() {
}
}
);
