我的miniQuery

　　经过两周的JS OOP学习，为了记录这难忘的时刻，写了一个mini的Query

下面便是代码咯！

(function(){
    
    //构建变量保存window.
    var _$ = window.$;
    var _Query = window.Query;
    
    var Query = window.Query = window.$ = function(selector){
        return new Query.fn.init(selector);
    }
    
    //处理原型
    Query.fn = Query.prototype = {
        
        //给这个包添加一个初始化方法
        init : function(selector){
        
            //获取所有选择器指定的元素对象
            var eles = document.querySelectorAll(selector);
            
            //将所有元素添加到this中，形成对象型数组
            Array.prototype.push.apply(this,eles);
            
            //将this返回
            return this;
        },
        Query : "1.0.0",
        length : 0,
        size : function (){
            return this.length;
        }
    };
    
    //
    Query.fn.init.prototype = Query.fn;
    
    //实现继承，通过调用这个方法，可以不断的为Query添加功能
    //添加静态        //添加实例
    Query.exdent = Query.fn.exdent = function(){
        //参数是一个对象
        var o = (arguments[0] instanceof Object ? arguments[0] : {});
        //将对象的属性和属性值一个个动态添加到this中
        for(p in o){
            this[p] = o[p];
        }
    }
    
    //添加静态方法
    Query.exdent({
        //解决冲突
        noConflict: function( deep ) {
            window.$ = _$;

通过Query.exdent和Query.fn.endent方法，可以为Query添加无数静态方法，原型方法！有兴趣的朋友可以拿过去试一试！虽然有些东西考虑的不完善。。。
