Javascript对象通信并从其他对象获取参数

Question

我在将参数从一个对象共享到另一个对象时遇到问题 我有一个带有选项的 LatestVideos 对象，我的视频画廊和其他具有分页、渲染、类别和 LocalStorage 方法的对象，女巫手举所有功能，但我使用这个很多，我需要这个作为单独的对象

    (function (window, document, none) {
  "use strict";
  var LatestVideos = window.LatestVideos = function (option) {
   /* object to init puglin data JSON FORMAT keys Jsondata or url , container, 
   actual page wrapper on paggination, number of item per page, categorywrapper*/
    this.fragments = document.createDocumentFragment();
    this.categories = ["Favorite"];
    this.statusLoad = 0;
    this.allid = [];
    this.categoryid = [];
    this.actual = [];
    //this.categoryChecked=[];
    this.page = 0;
    loadJSON(option.url,this.initData.bind(this));     
    this.settings = { /// init data from options object from parameter constructor      
        JsonData :option.data || 0,       
        container : option.container,
        actpage : option.actpage || 1, 
        buttonwrapper : option.paginationwrapper,
        categorywrapper : option.categorywrapper,
        itemperpage : option.itemperpage,  // get value from prev Selection or default        
    };      
  }; 
  LatestVideos.prototype.initData = function (data) { // assinchrounous call json with ajax
      this.settings.JsonData = data;
      this.settings.lengthData = data.length;
      Render.setData(this);
      Render.getCategories();
  };
  var Render = { // need this data from LASTESTVIDEOS    data,conteiner,paginationwrapper,categorywrapper
    /// object with method  to render articles to my website
  };
  var Pagination = function(){
    //   from LASTESTVIDEOS I need JsonData, actPage overide page and paginatorwrapper
    // object with method to calculate number of pages and paginate my articles
  };
  var Cateogry = function(){
     //   from LASTESTVIDEOS categoryid change actual and allid 
    // object with method to changeCategory and get category from data atribut 
   };
  var LocalStoraget = function (){
    // I JSON data from LASTESTVIDEOS
    // object with method to getFavorite item form localstorage and add to localstorage
};
})(window, document);


function loadJSON(url, callback) {  
  /* function to load ajax from url input(url- form and callback function),
 output function call and post (ARRAY JSON OBJECTS)*/
  var xmlhttp =0;
  if (typeof XMLHttpRequest !== 'undefined') {
    xmlhttp = new XMLHttpRequest();
  } else {
    var versions = ["Microsoft.XmlHttp",
        "MSXML2.XmlHttp",
        "MSXML2.XmlHttp.3.0",
        "MSXML2.XmlHttp.4.0",
        "MSXML2.XmlHttp.5.0"];
    var len =  versions.length;
    for (var i = 0; i < len; i++) {
      try {
        xmlhttp = new ActiveXObject(versions[i]);
        break;
      }
      catch(e){}
  } 
}
xmlhttp.onreadystatechange = ensureReadiness;
function ensureReadiness(){
  if (xmlhttp.readyState === 4 && xmlhttp.status === 200)
  {
    JSONObject = JSON.parse(xmlhttp.responseText);
    callback (JSONObject);
  }else{
    return;
  }
}
xmlhttp.open("GET",url,true);
xmlhttp.send();
}
var options = {url:"someURL",container:"videox",paginationwrapper:"pages"};
var opp = new LatestVideos(options);

这是一个插件，我需要使用不同的选项创建 xtimes，有时我需要单独渲染或分页对象或本地存储

我可能会稍微改变一下：

var Render = function (options) { 
  this.options = $.extend({ //default options
    data: [],
    container: null
  }, options);

  // use internal logic here
  var getCategories = function(){
    ...
  };
  // and return public methods

  return {
    getCategories: getCategories
  };
};

并将 LatestVideos 中的代码更改为以下内容：

LatestVideos.prototype.initData = function (data) { // assinchrounous call json with ajax
      this.settings.JsonData = data;
      this.settings.lengthData = data.length;
      var renderer = new Render({
          data: this.settings.JsonData,
          container: this.settings.container
      });
      renderer.getCategories();
  };
