Window 接口表示的窗口包含 DOM 文档； document 特性指向 DOM 文档 加载在相应窗口中。 可以获得给定文档的窗口使用 document.defaultView 特性。

全局变量 window 表示的窗口脚本在其中运行，并暴露给 JavaScript 代码。

Window 接口是各种函数、名称空间、对象及构造函数的家园，它们不必直接关联用户界面窗口概念。不管怎样， Window 接口是包括这些需要全局可用的项的合适位置。其中许多被文档化在 JavaScript 参考 和 DOM 参考 .

在选项卡式浏览器中，表示每个选项卡通过它自己的 Window 对象；全局 window 理解始终在其中运行代码的选项卡表示，通过在给定选项卡中运行 JavaScript 代码。也就是说，即使在选项卡式浏览器中，某些特性和方法仍适用于包含选项卡的整个窗口，如 resizeTo() and innerHeight 。通常，不能合理附属于选项卡的任何东西都属于窗口。 

  <div id="interfaceDiagram" style="display: inline-block; position: relative; width: 100%; padding-bottom: 11.666666666666666%; vertical-align: middle; overflow: hidden;"><svg style="display: inline-block; position: absolute; top: 0; left: 0;" viewbox="-50 0 600 70" preserveAspectRatio="xMinYMin meet"><a xlink:href="../API/Window" target="_top"><rect x="1" y="1" width="75" height="50" fill="#F4F7F8" stroke="#D4DDE4" stroke-width="2px" /><text  x="38.5" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">Window</text></a></svg></div>
