pandorajspandora-class
提供简单的 OO 实现
安装
$ spm install pandora-class --save使用说明
创建类
var Class = require('pandora-class');
var Person = Class.create({
initialize: function (name, age) {
this.name = name;
this.age = age;
}
});
对类扩展（继承）
var Student = Person.extend({
//initialize是内置的初始化方法，实例化时自动执行
initialize: function (name, age, school) {
Student.superclass.initialize.apply(this, arguments);
//superclass是Student的父类，也就是Person，这句是调用父类的初始化方法。
this.school = school;
}
});
或
var Student = Class.create(Person, {
initialize: function (name, age, school) {
Student.superclass.initialize.apply(this, arguments);
this.school = school;
}
});
对实例扩展
var person = new Person('xiaoming', 18);
person.extend({
showName: function () {
console.log(this.name);
}
});
person.showName(); //xiaoming混入
var proto1 = {
height: 175
},
proto2 = {
getHeight: function() {
return this.height;
}
};然后通过以下方式把属性或方法混入到类里。
var Student = Person.extend({
mixins: [proto1, proto2]
});或
var Student = Class.create(Person,{
mixins: [proto1, proto2]
});混入后，Student就拥有height属性和getHeight()方法。
