my simple vquery test ---like jquery

gistfile1.js

//vquery verson 1.0
(function(){
  //the magic dollar
  var $ = function(sel){
    return new $.prototype.init(sel);
  }
  //代理方法
  $.prototype.init.prototype = $.fn = $.prototype;
  //原型扩展
  $.prototype = {
    init:function(sel){
      this.selectors = document.querySelector(sel);
      //如果当前为空 就新建一个
      if(!this.selectors){
        //新建什么类型 判断比较复杂。。。不写了
      }
      this.copyright = {
        "version":"1.0",
        "author":"viking"
      }  
    },
    css:function(prop,value){
      this.selectors.style[prop] = value;
      return this;
    },
    html:function(html){
      this.selectors.innerHTML = html;
      return this;
    },
    delete:function(){
      this.selectors.parentNode.removeChild(this.selectors);
      return this;
    },
    append:function(newnode){
      this.selectors.appendChild(newnode);
      return this;
    },
    //simple events stuff
    addEvent:function(type,callback){
      this.selectors.addEventListener(type,callback,false);
      return this;
    }
  }
  //add extra stuff on $ object like ajax utils...
  $.ajax = function(opts,callback){
    console.log('i am a xhr stuff')
  }
  $.ready = function(callback){
    window.addEventListener('DOMContentLoaded',callback,false);
  }
  //exports to window
  window.V = window.miniVan = $;
})()

//examples
V.ready(function(){
  V('#test').css('font-size','20px').html('new hello world');
  V('#test2').addEvent('click',function(e){
    console.log('you clicked on div#'+e.target.id);
  })
  $.ajax({method:'GET',url:'fuckme.com/rest/video/1',dataType:'json'},function(data){
    console.log(data);
  })
})
