The HTMLIFrameElement
interface provides special properties and methods (beyond those of the HTMLElement
interface it also has available to it by inheritance) for manipulating the layout and presentation of inline frame elements.

Methods
Inherits properties from its parent, HTMLElement
.
Browser API methods
To support the requirement of a browser <iframe>
, HTMLIFrameElement
has been extended with new methods that give the <iframe>
some super powers. These are non-standard (see Browser compatibility.)
Navigation methods
The following navigation methods allow navigation through the browsing history of the <iframe>
. They are necessary to be able to implement back, forward, stop, and reload buttons.
HTMLIFrameElement.reload()
- Allows reloading of the
<iframe>
element content. HTMLIFrameElement.stop()
- Allows stopping of the
<iframe>
's content loading. HTMLIFrameElement.getCanGoBack()
- Indicates whether it's possible to navigate backwards.
HTMLIFrameElement.goBack()
- Changes the location of the
<iframe>
for the previous location in its browsing history. HTMLIFrameElement.getCanGoForward()
- Indicates whether it's possible to navigate forward.
HTMLIFrameElement.goForward()
- Changes the location of the
<iframe>
for the next location in its browsing history.
Management methods
The next set of methods manage the resources used by a browser <iframe>
. These are especially useful for implementing tabbed browser application.
HTMLIFrameElement.executeScript()
- Allows a specified script to be executed against a page loaded in the browser
<iframe>
. HTMLIFrameElement.purgeHistory()
- Clears all the resources (cookies, localStorage, cache, etc.) associated with the browser
<iframe>
. HTMLIFrameElement.setVisible()
- Changes the visibility state of a browser
<iframe>
. This can influence resource allocation and some function usage such asrequestAnimationFrame
. HTMLIFrameElement.getVisible()
- Indicates the current visibility state of the browser
<iframe>
. HTMLIFrameElement.setActive()
- Sets the current
<iframe>
as the active frame, which has an effect on how it is prioritized by the process manager. HTMLIFrameElement.getActive()
- Indicates whether the current browser
<iframe>
is the currently active frame. HTMLIFrameElement.setInputMethodActive()
- Sets the current browser
<iframe>
as an active IME window and other iframes as non-active IME windows. Useful when a top level app wants to activate a window as an IME (Input Method Editor, like a keyboard.) HTMLIFrameElement.setNfcFocus()
Firefox OS 2.2+ Only- Part of the Firefox OS NFC API, extending the Browser API, this sets whether a browser
<iframe>
can receive an NFC event.
Audio-related methods
The following methods allow direct control of sound in the browser element.
HTMLIFrameElement.getVolume()
Firefox OS 2.5+ Only- Gets the current volume of the browser
<iframe>
. HTMLIFrameElement.setVolume()
Firefox OS 2.5+ Only- Sets the current volume of the browser
<iframe>
. HTMLIFrameElement.mute()
Firefox OS 2.5+ Only- Mutes any audio playing in the browser
<iframe>
. HTMLIFrameElement.unmute()
Firefox OS 2.5+ Only- Unmutes any audio playing in the browser
<iframe>
. HTMLIFrameElement.getMuted()
Firefox OS 2.5+ Only- Indicates whether the browser
<iframe>
is currently muted.
Search methods
New methods are provided to allow programmatic searches of browser <iframe>
s to be carried out.
HTMLIFrameElement.findAll()
Firefox OS 2.5+ Only- Searches for a string in a browser
<iframe>
's content; if found, the first instance of the string relative to the caret position will be highlighted. HTMLIFrameElement.findNext()
Firefox OS 2.5+ Only- Highlights the next or previous instance of a search result after a
findAll()
search has been carried out. HTMLIFrameElement.clearMatch()
Firefox OS 2.5+ Only- Clears any content highlighted by
findAll()
orfindNext()
.
Event-related methods
In order to manage the browser <iframe>
's content, many new events were added (see below). The following methods are used to deal with those events:
- The
<iframe>
gains support for the methods of theEventTarget
interface addEventListener()
,removeEventListener()
, anddispatchEvent()
.HTMLIFrameElement.sendMouseEvent()
- Sends a
MouseEvent
to the<iframe>
's content. HTMLIFrameElement.sendTouchEvent()
- Sends a
TouchEvent
to the<iframe>
's content. Note that this method is available for touch enabled devices only. HTMLIFrameElement.addNextPaintListener()
- Defines a handler to listen for the next
MozAfterPaint
event in the browser<iframe>
. HTMLIFrameElement.removeNextPaintListener()
- Removes a handler previously set with
addNextPaintListener()
.
Utility methods
Last, there are some utility methods, useful for apps that host a browser <iframe>
.
HTMLIFrameElement.download()
- Downloads a specified URL, storing it at the specified filename/path.
HTMLIFrameElement.getContentDimensions()
- Retrieves the X and Y dimensions of the content window.
HTMLIFrameElement.getManifest()
Firefox OS 2.5+ Only- Retrieves the manifest of an app loaded in the browser
<iframe>
and returns it as JSON. HTMLIFrameElement.getScreenshot()
- Takes a screenshot of the browser
<iframe>
's content. This is particularly useful to get thumbnails of tabs in a tabbed browser app. HTMLIFrameElement.getStructuredData()
Firefox OS 2.5+ Only- Retrieves any structured microdata (and hCard and hCalendar microformat data) contained in the HTML loaded in the browser
<iframe>
and returns it as JSON. HTMLIFrameElement.zoom()
- Changes the zoom factor of the browser
<iframe>
's content. This is particularly useful for zooming in/out on non-touch-enabled devices.

- [1] Previously, the type of
sandbox
was aDOMString
instead of aDOMSettableTokenList
. This has been fixed with Gecko 29.0 (Firefox 29 / Thunderbird 29 / SeaMonkey 2.26)) (bug 845067). Other browsers may still implement the property asDOMString
since it was a late change in the specification. - [2] Requires privileged app, and
browser
and/orembed-apps
permissions, depending on what you want to do. See Using the Browser API for more details. Most of the proprietary Browser API methods are supported from Firefox OS 1.0.1 onwards; they are marked where this is not the case. - [3] For older version use
HTMLIFrameElement.contentWindow.document
instead. - [4] Daily test builds only.
- [5] Supported in chrome code only.
