onclick go full screen

I'm creating a web-app for the upcoming Chrome Web-store. Is there a way to simulate F11 being pressed? Or simply a command that will make the current window go full screen?

I tried other answers on this question, and there are mistakes with the different browser APIs, particularly Fullscreen vs FullScreen. Here is my code that works with the major browsers (as of Q1 2019) and should continue to work as they standardize.

function fullScreenTgl() {
    let doc=document,elm=doc.documentElement;
    if      (elm.requestFullscreen      ) { (!doc.fullscreenElement   ? elm.requestFullscreen()       : doc.exitFullscreen()        ) }
    else if (elm.mozRequestFullScreen   ) { (!doc.mozFullScreen       ? elm.mozRequestFullScreen()    : doc.mozCancelFullScreen()   ) }
    else if (elm.msRequestFullscreen    ) { (!doc.msFullscreenElement ? elm.msRequestFullscreen()     : doc.msExitFullscreen()      ) }
    else if (elm.webkitRequestFullscreen) { (!doc.webkitIsFullscreen  ? elm.webkitRequestFullscreen() : doc.webkitCancelFullscreen()) }
    else                                  { console.log("Fullscreen support not detected.");                                          }
    }

var elem = document.getElementById("myvideo");
function openFullscreen() {
  if (elem.requestFullscreen) {
      elem.requestFullscreen();
  } else if (elem.mozRequestFullScreen) { /* Firefox */
      elem.mozRequestFullScreen();
  } else if (elem.webkitRequestFullscreen) { /* Chrome, Safari & Opera */
      elem.webkitRequestFullscreen();
  } else if (elem.msRequestFullscreen) { /* IE/Edge */
      elem.msRequestFullscreen();
  }
}
//Internet Explorer 10 and earlier does not support the msRequestFullscreen() method.

Short personal bookmarklet version

javascript: document.body.webkitRequestFullScreen();

go fullscreen ← You can drag this link to your bookmark bar to create the bookmarklet, but you have to edit its URL afterwards: Delete everything before javascript, including the single slash: ~~http://delete_me/~~javascript:[…]

This works for me in Google Chrome. You have to test whether it works in your environment and otherwise use a different wording of the function call, e.g. javascript:document.body.requestFullScreen(); – see the other answers for the possible variants.

//set height of html
$("html").css("height", screen.height);
//set width of html
$("html").css("width", screen.width);
//go to full screen mode
document.documentElement.webkitRequestFullscreen();

If you want to switch the whole tab to fullscreen (just like F11 keypress) document.documentElement is the element you are looking for:

function go_full_screen(){
    var elem = document.documentElement;
    if (elem.requestFullscreen) {
      elem.requestFullscreen();
    } else if (elem.msRequestFullscreen) {
      elem.msRequestFullscreen();
    } else if (elem.mozRequestFullScreen) {
      elem.mozRequestFullScreen();
    } else if (elem.webkitRequestFullscreen) {
      elem.webkitRequestFullscreen();
    }
}

It's possible with JavaScript.

var elem = document.getElementById("myvideo");
if (elem.requestFullscreen) {
  elem.requestFullscreen();
} else if (elem.msRequestFullscreen) {
  elem.msRequestFullscreen();
} else if (elem.mozRequestFullScreen) {
  elem.mozRequestFullScreen();
} else if (elem.webkitRequestFullscreen) {
  elem.webkitRequestFullscreen();
}

I realize this is a very old question, and that the answers provided were adequate, since is active and I came across this by doing some research on fullscreen, I leave here one update to this topic:

There is a way to "simulate" the F11 key, but cannot be automated, the user actually needs to click a button for example, in order to trigger the full screen mode.

Toggle Fullscreen status on button click

With this example, the user can switch to and from fullscreen mode by clicking a button:

HTML element to act as trigger:

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

JavaScript:

function toggleFullScreen() {
  if ((document.fullScreenElement && document.fullScreenElement !== null) ||    
   (!document.mozFullScreen && !document.webkitIsFullScreen)) {
    if (document.documentElement.requestFullScreen) {  
      document.documentElement.requestFullScreen();  
    } else if (document.documentElement.mozRequestFullScreen) {  
      document.documentElement.mozRequestFullScreen();  
    } else if (document.documentElement.webkitRequestFullScreen) {  
      document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);  
    }  
  } else {  
    if (document.cancelFullScreen) {  
      document.cancelFullScreen();  
    } else if (document.mozCancelFullScreen) {  
      document.mozCancelFullScreen();  
    } else if (document.webkitCancelFullScreen) {  
      document.webkitCancelFullScreen();  
    }  
  }  
}

Go to Fullscreen on button click

This example allows you to enable full screen mode without making alternation, ie you switch to full screen but to return to the normal screen will have to use the F11 key:

HTML element to act as trigger:

<input type="button" value="click to go fullscreen" onclick="requestFullScreen()">

JavaScript:

function requestFullScreen() {

  var el = document.body;

  // Supports most browsers and their versions.
  var requestMethod = el.requestFullScreen || el.webkitRequestFullScreen 
  || el.mozRequestFullScreen || el.msRequestFullScreen;

  if (requestMethod) {

    // Native full screen.
    requestMethod.call(el);

  } else if (typeof window.ActiveXObject !== "undefined") {

    // Older IE.
    var wscript = new ActiveXObject("WScript.Shell");

    if (wscript !== null) {
      wscript.SendKeys("{F11}");
    }
  }
}
