How to make browser full screen using F11 key event through JavaScript [duplicate]

Question

This question already has an answer here:

• Set window to fullscreen (REAL fullscreen; F11 functionality) by javascript 6 answers

I want to make my browser full screen. Same as when we do F11 key event. I found some examples such as

function maxwin() {
    var wscript = new ActiveXObject("WScript.Shell");
    if (wscript!=null) {
         wscript.SendKeys("{F11}");
    }
}

Which does not work on mozilla or any other latest browsers. Please let me know if there is any way to sort out this problem.

Thanks. (In advance.)

Answer 1

use this code instead

var el = document.documentElement
, rfs = // for newer Webkit and Firefox
       el.requestFullScreen
    || el.webkitRequestFullScreen
    || el.mozRequestFullScreen
    || el.msRequestFullScreen
;
if(typeof rfs!="undefined" && rfs){
  rfs.call(el);
} else if(typeof window.ActiveXObject!="undefined"){
  // for Internet Explorer
  var wscript = new ActiveXObject("WScript.Shell");
  if (wscript!=null) {
     wscript.SendKeys("{F11}");
  }
}

Works and tested on Chrome, FF10 above, IE 8 above, Safari 5..

Answer 2

This is now possible in the latest versions of Chrome, Firefox and IE(11).

Following the pointers by Zuul on this thread, I edited his code to include IE11 and the option to full screen any element of choice on your page.

JS:

function toggleFullScreen(elem) {
    // ## The below if statement seems to work better ## if ((document.fullScreenElement && document.fullScreenElement !== null) || (document.msfullscreenElement && document.msfullscreenElement !== null) || (!document.mozFullScreen && !document.webkitIsFullScreen)) {
    if ((document.fullScreenElement !== undefined && document.fullScreenElement === null) || (document.msFullscreenElement !== undefined && document.msFullscreenElement === null) || (document.mozFullScreen !== undefined && !document.mozFullScreen) || (document.webkitIsFullScreen !== undefined && !document.webkitIsFullScreen)) {
        if (elem.requestFullScreen) {
            elem.requestFullScreen();
        } else if (elem.mozRequestFullScreen) {
            elem.mozRequestFullScreen();
        } else if (elem.webkitRequestFullScreen) {
            elem.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
        } else if (elem.msRequestFullscreen) {
            elem.msRequestFullscreen();
        }
    } else {
        if (document.cancelFullScreen) {
            document.cancelFullScreen();
        } else if (document.mozCancelFullScreen) {
            document.mozCancelFullScreen();
        } else if (document.webkitCancelFullScreen) {
            document.webkitCancelFullScreen();
        } else if (document.msExitFullscreen) {
            document.msExitFullscreen();
        }
    }
}

HTML:

<input type="button" value="click to toggle fullscreen" onclick="toggleFullScreen(document.body)">

Where "document.body" is any element you so wish.

Also note that trying to run these full screen commands from the console do not appear to work on Chrome or IE. I did have success with Firebug in Firefox though.

One other thing to note is that these "full screen" commands don't have a vertical scrollbar, you need to specify this within the CSS:

*:fullscreen
*:-ms-fullscreen,
*:-webkit-full-screen,
*:-moz-full-screen {
   overflow: auto !important;
}

The "!important" seems to be necessary for IE to render it

Answer 3

Not possible without native code or a browser extension. The ActiveXObject only exists in the IE browser.

Answer 4

now a days it is possible (at least webkit browsers at safari 5, chrome 16) with the

 webkitEnterFullscreen()

Firefox 10 also works. check this link
