• v1.3.0 之前版本的extend会污染this对象，已重构
• v1.2.6（todo） 使用mocha重构test
• v1.2.5 修改代码内版本号和作者，以及dist

第一版

源码

module.exports = global.Class = function(name, src) { 
    src.constructor.prototype = src; 
    global[name] = src.constructor; 
}; 

用法

var $ = require('./index')

$('Person',{
    constructor: function(name) { 
        this.name = name;
    }, 
    say: function(){
        console.log('hello ' + this.name);
    }
})

var p = new Person('alfred sang');
p.say();

还是蛮舒服的吧？

第二版

这个版本主要增加了继承功能，具体用法如下

基本用法

没有构造函数的情况

$('Person1',{
    say: function(){
        console.log('hello ' + this.name);
    }
})

var p1 = new Person1();
p1.name = 'i5ting'
console.log(p1);
p1.say();

有构造函数的情况

var $ = require('./index')

$('Person',{
    constructor: function(name) { 
        this.name = name;
    }, 
    say: function(){
        console.log('hello ' + this.name);
    }
})

var p = new Person('alfred sang');
p.say();

测试1：plain object继承

var $ = require('./index')

$('Person',{
    constructor: function(name) { 
        console.log('---1----');
        this.name = name;
    }, 
    bbb:'bbb',
    hello:function(){
        console.log('hello');
    }
},
{
    constructor: function(name) { 
        console.log('---2----');
        this.name = name;
    
    }, 
    say: function(){
        console.log('hello ' + this.name);
        console.log(this.bbb);
    }
})

var p = new Person('alfred sang');
p.hello()
p.say();

测试2：使用已有对象完成继承

var $ = require('./index')

$('Base',{
    constructor: function(name) { 
        this.name = name;
    },
    hello:function(){
        console.log('hello');
    }
})

var base = new Base('a person');

$('Person',base,{
    constructor: function(name) { 
        this.name = name;
    }, 
    say: function(){
        console.log('hello ' + this.name);
        this.hello();
    }
})

var p = new Person('alfred sang');
p.say();
p.hello();

测试3：使用继承对象的原型方法

var $ = require('./index')

var Base = function(name){
    this.name = name;
}

Base.prototype.hello = function(){
    console.log('---Base.prototype.hello----');
}

var base = new Base('a person');

$('Person',base,{
    constructor: function(name) { 
        this.name = name;
    }, 
    say: function(){
        console.log('hello ' + this.name);
        this.hello();
    }
})

var p = new Person('alfred sang');
p.say();

Test

npm test

or

node test

结果

➜  node-mini-obj git:(master) ✗ npm test

> node-mini-obj@1.0.0 test /Users/sang/workspace/github/node-mini-obj
> node test

hello alfred sang

TODO

• 使用init作为构造函数
• 使用this._super调用父类方法
• 完善的继承链

Building

If you need to use this module outside a CommonJS environment, you can build a standalone UMD module as follows:

npm install -g uglify-js
npm install -g browserify

$ browserify index.js --standalone Espresso | uglifyjs > node-mini-obj.min.js
