<p><strong><code>Document.location</code></strong> 是一个只读属性，返回一个 {{domxref("Location")}} 对象，包含有文档的 URL 相关的信息，并提供了改变该 URL 和加载其他 URL 的方法。</p>
<p>尽管 <code>Document.location</code> 是一个只读的 <code>Location</code> 对象，你也能够赋给它一个 {{domxref("DOMString")}}。这意味着你能够赋给 document.location 字符串，大多数情况下像这样使用：<code>document.location = 'http://www.example.com'</code>，也可写为<code>document.location.href = 'http://www.example.com'</code>。</p>
<p>只是想获取字符串形式的 URL，可以使用只读属性 {{domxref("document.URL")}}。</p>
<p>If the current document is not in a browsing context, the returned value is <code>null</code>.</p>
