在全局范圍內輕松訪問函數中的類變量

Question

我有一個對象

var long_object_name = {
  'init':function(){

    this.properties.the_screen_size[0] = window.innerWidth;
    this.properties.the_screen_size[1] = window.innerHeight;

    window.addEventListener('resize', function(){
      long_object_name.properties.the_screen_size[0] = window.innerWidth;
      long_object_name.properties.the_screen_size[1] = window.innerHeight;
    }, false);
  },
  'properties':{
    'the_screen_size':[]
  }
}

所以我想將屏幕大小存儲在一個變量中，該變量在用戶更改窗口大小時會發生變化。
問題是在重新調整大小事件函數中我要鍵入“long_object_name”以“到達”“屬性”對象。 所以我的問題是，有沒有辦法以另一種方式“到達”“屬性”對象，例如像“this.properties”但是“this”在這種情況下不起作用，對吧？

Answer 1

var long_object_name = {
  'init':function(){

    var screenSize = this.properties.the_screen_size;

    screenSize[0] = window.innerWidth;
    screenSize[1] = window.innerHeight;

    window.addEventListener('resize', function(){
      screenSize[0] = window.innerWidth;
      screenSize[1] = window.innerHeight;
    }, false);
  },
  'properties':{
    'the_screen_size':[]
  }
}

Answer 2

var long_object_name = {
  'init':function(){

    var ss = this.properties.the_screen_size;

    ss[0] = window.innerWidth;
    ss[1] = window.innerHeight;

    window.addEventListener('resize', function(){
      ss[0] = window.innerWidth;
      ss[1] = window.innerHeight;
    }, false);
  },
  'properties':{
    'the_screen_size':[]
  }
}
