How to make browser full screen using F11 key event through JavaScript
提问by Delmond
I want to make my browser full screen. Same as when we do F11 key event. I found some examples such as
我想让我的浏览器全屏显示。与我们执行 F11 键事件时相同。我发现了一些例子，例如
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.
这不适用于 mozilla 或任何其他最新浏览器。请让我知道是否有任何方法可以解决这个问题。
Thanks. (In advance.)
谢谢。（提前。）

use this code instead
改用此代码
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}");
}
}

This is now possible in the latest versions of Chrome, Firefox and IE(11).
这现在可以在最新版本的 Chrome、Firefox 和 IE(11) 中实现。
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.
按照 Zuul 在此线程上的指示，我编辑了他的代码以包含 IE11 和全屏显示页面上任何选择元素的选项。
JS:
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:
HTML：
<input type="button" value="click to toggle fullscreen" onclick="toggleFullScreen(document.body)">
Where "document.body" is any element you so wish.
其中“document.body”是您希望的任何元素。
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.
另请注意，尝试从控制台运行这些全屏命令似乎不适用于 Chrome 或 IE。不过，我确实在 Firefox 中使用 Firebug 取得了成功。
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:
需要注意的另一件事是这些“全屏”命令没有垂直滚动条，您需要在 CSS 中指定：
*:fullscreen
*:-ms-fullscreen,
*:-webkit-full-screen,
*:-moz-full-screen {
overflow: auto !important;
}
The "!important" seems to be necessary for IE to render it
"!important" 似乎是 IE 渲染它所必需的

Not possible without native code or a browser extension. The ActiveXObject only exists in the IE browser.
没有本机代码或浏览器扩展是不可能的。ActiveXObject 只存在于 IE 浏览器中。
