<div>{{APIRef("HTML DOM")}}</div>

<p>The <strong><code>HTMLIFrameElement</code></strong> interface provides special properties and methods (beyond those of the {{domxref("HTMLElement")}} interface it also has available to it by inheritance) for manipulating the layout and presentation of inline frame elements.</p>

<h2 id="Methods">Methods</h2>

<p><em>Inherits properties from its parent, {{domxref("HTMLElement")}}</em>.</p>

<h3 id="Browser_API_methods">Browser API methods</h3>

<p>To support the requirement of a browser {{HTMLElement("iframe")}}, <code>HTMLIFrameElement</code> has been extended with new methods that give the {{HTMLElement("iframe")}} some super powers. These are non-standard (see {{anch("Browser compatibility")}}.)</p>

<h4 id="Navigation_methods">Navigation methods</h4>

<p>The following navigation methods allow navigation through the browsing history of the {{HTMLElement("iframe")}}. They are necessary to be able to implement back, forward, stop, and reload buttons.</p>

 <dt>{{domxref("HTMLIFrameElement.goForward()")}}</dt>
 <dd>Changes the location of the {{HTMLElement("iframe")}} for the next location in its browsing history.</dd>
</dl>

<h4 id="Management_methods">Management methods</h4>

<p>The next set of methods manage the resources used by a browser {{HTMLElement("iframe")}}. These are especially useful for implementing tabbed browser application.</p>

<dl>
 <dt>{{domxref("HTMLIFrameElement.executeScript()")}}</dt>
 <dd>Allows a specified script to be executed against a page loaded in the browser {{HTMLElement("iframe")}}.</dd>
 <dt>{{domxref("HTMLIFrameElement.purgeHistory()")}}</dt>
 <dd>Clears all the resources (cookies, localStorage, cache, etc.) associated with the browser {{HTMLElement("iframe")}}.</dd>
 <dt>{{domxref("HTMLIFrameElement.setVisible()")}}</dt>
 <dd>Changes the visibility state of a browser {{HTMLElement("iframe")}}. This can influence resource allocation and some function usage such as {{domxref("window.requestAnimationFrame","requestAnimationFrame")}}.</dd>

 <dd>Indicates the current visibility state of the browser {{HTMLElement("iframe")}}.</dd>
 <dt>{{domxref("HTMLIFrameElement.setActive()")}}</dt>
 <dd>Sets the current {{HTMLElement("iframe")}} as the active frame, which has an effect on how it is prioritized by the process manager.</dd>

 <dd>Indicates whether the current browser {{htmlelement("iframe")}} is the currently active frame.</dd>
</dl>

 <dd>Unmutes any audio playing in the browser {{HTMLElement("iframe")}}.</dd>
 <dt>{{domxref("HTMLIFrameElement.getMuted()")}}</dt>
 <dd>Indicates whether the browser {{HTMLElement("iframe")}} is currently muted.</dd>
</dl>

<h4 id="Search_methods">Search methods</h4>

<p>New methods are provided to allow programmatic searches of browser {{HTMLElement("iframe")}}s to be carried out.</p>

<dl>
 <dt>{{domxref("HTMLIFrameElement.findAll()")}}</dt>

</dl>

<h4 id="Event-related_methods">Event-related methods</h4>

<p>In order to manage the browser {{HTMLElement("iframe")}}'s content, many new events were added (see below). The following methods are used to deal with those events:</p>

<dl>
 <dt>The {{HTMLElement("iframe")}} gains support for the methods of the {{domxref("EventTarget")}} interface</dt>

 <dt>{{domxref("HTMLIFrameElement.getScreenshot()")}}</dt>
 <dd>Takes a screenshot of the browser {{HTMLElement("iframe")}}'s content. This is particularly useful to get thumbnails of tabs in a tabbed browser app.</dd>
 <dt>{{domxref("HTMLIFrameElement.getStructuredData()")}}</dt>
 <dd>Retrieves any structured microdata (and hCard and hCalendar microformat data) contained in the HTML loaded in the browser {{HTMLElement("iframe")}} and returns it as JSON.</dd>
 <dt>{{domxref("HTMLIFrameElement.zoom()")}}</dt>

 <li>[1] Previously, the type of <code>sandbox</code> was a {{domxref("DOMString")}} instead of a {{domxref("DOMSettableTokenList")}}. This has been fixed with <a href="/en-US/Firefox/Releases/29/Site_Compatibility">Gecko 29.0</a> {{geckoRelease(29)}}) ({{bug(845067)}}). Other browsers may still implement the property as <code>DOMString</code> since it was a late change in the specification.</li>
 <li>[3] For older version use <code>HTMLIFrameElement.contentWindow.document</code> instead.</li>
 <li>[4] Daily test builds only.</li>
 <li>[5] Supported in chrome code only.</li>
