      JavaScript 的系统了解

      JS 在网页中的宿主是浏览器;

      浏览器中 window 是顶级作用域;

      以前在研究 JS 中类的概念时候也有看;

      但是没有逐个属性的查看;

      今天输出来,逐个看下,查漏补缺;

      JS 代码如下

      var windowKeyAry=[];//用于储存window上的属性/方法
      for (key in window){
          windowKeyAry.push(key);//把便利到的key push 到数组里;
      }
      windowKeyAry.sort(function (a, b) {return a.localeCompare(b);});//排序
      
      console.log(windowKeyAry.length);//查看当前浏览器window属性的数量   注:不同浏览器,或者同一浏览器的不同版本中数量不一致
      document.write(windowKeyAry);
      

      下面是看不同浏览器中的表现了;

      Chrome:197 个属性(我用的 Chrome 版本 60.0.3112.101(正式版本) (64 位), 不同的版本属性可能会有不同的出入)

      这里 window 的属性如下:(为了方便查看,我做了整理)
