<div></div>

<p>Каждая веб-страница, которая загружается в браузер, имеет свой собственный объект <strong>document</strong>. Интерфейс документа служит точкой входа для получения содержимого веб-страницы (всего <a href="/en-US/docs/Using_the_W3C_DOM_Level_1_Core" title="Using_the_W3C_DOM_Level_1_Core">DOM</a> - дерева, включая такие элементы как {{HTMLElement("body")}} и {{HTMLElement("table")}}), <span id="result_box" lang="ru"><span>а также обеспечивает функциональность</span><span>, которая является</span> <span>глобальной для</span> <span>документа</span>, <span>например, для получения</span> <span>URL-адреса </span><span>страницы</span> <span>и</span>ли <span>создания новых элементов</span> <span>в документе</span></span>).</p>

<p>Объект <strong>document</strong> может быть получен из разных API:</p>

<ul>
 <li>Чаще всего используется прямой доступ к объекту <strong>document</strong> из сценариев <a href="/en-US/docs/HTML/Element/Script" title="HTML/Element/Script">scripts</a> которые подгружаются документом. (Этот же объект доступен как {{domxref("window.document")}}.)</li>
 <li>Через свойство <code><a href="/en-US/docs/Web/API/HTMLIFrameElement#Properties" title="DOM/HTMLIFrameElement#Properties">contentDocument</a></code> объекта iframe.</li>
 <li>Как ответ <a href="/en-US/docs/Web/API/XMLHttpRequest#responseXML" title="XMLHttpRequest#responseXML"><code>responseXML</code></a> объекта  <a href="/en-US/docs/Web/API/XMLHttpRequest" title="XMLHttpRequest"><code>XMLHttpRequest.</code></a></li>
 <li>Доступ к документу может быть получен из элемента или узла через свойство  {{domxref("Node.ownerDocument","ownerDocument")}}.</li>
</ul>

<p>В зависимости от вида документа (т.е. <a href="/en-US/docs/HTML" title="HTML">HTML</a> или <a href="/en-US/docs/XML" title="XML">XML</a>) у объекта <strong>document</strong> могут быть доступны разные API.</p>

<ul>
 <li>Все объекты документов реализуют интерфейс <a href="http://dom.spec.whatwg.org/#interface-document"><code>Document</code></a> (и следовательно {{domxref("Node")}} и {{domxref("EventTarget")}} интерфейсы). Таким образом основные свойства и методы, описанные на этой странице, доступны для всех видов документов.</li>
 <li>В современных браузерах некоторые документы (т.е. те, которые содержат контент <code>text/html</code>) также реагируют  {{domxref("HTMLDocument")}} интерфейс.</li>
 <li>В современных браузерах SVG документы реализуют {{domxref("SVGDocument")}} интерфейс.</li>
</ul>

<p>В будущем все эти интерфейсы будут сведены в один интерфейс - <code>Document</code>.</p>

<h2 id="Properties" name="Properties">Свойства</h2>
