如何使用JavaScript使访问者的浏览器全屏显示，同时兼容IE、Firefox和Opera?
当前回答
这将在全屏显示你的窗口
注意:要使其工作，您需要来自http://code.jquery.com/jquery-2.1.1.min.js的Query
或者让javascript链接像这样。
<script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>
<div id="demo-element">
<span>Full Screen Mode Disabled</span>
<button id="go-button">Enable Full Screen</button>
</div>
<script>
function GoInFullscreen(element) {
if(element.requestFullscreen)
element.requestFullscreen();
else if(element.mozRequestFullScreen)
element.mozRequestFullScreen();
else if(element.webkitRequestFullscreen)
element.webkitRequestFullscreen();
else if(element.msRequestFullscreen)
element.msRequestFullscreen();
}
function GoOutFullscreen() {
if(document.exitFullscreen)
document.exitFullscreen();
else if(document.mozCancelFullScreen)
document.mozCancelFullScreen();
else if(document.webkitExitFullscreen)
document.webkitExitFullscreen();
else if(document.msExitFullscreen)
document.msExitFullscreen();
}
function IsFullScreenCurrently() {
var full_screen_element = document.fullscreenElement || document.webkitFullscreenElement || document.mozFullScreenElement || document.msFullscreenElement || null;
if(full_screen_element === null)
return false;
else
return true;
}
$("#go-button").on('click', function() {
if(IsFullScreenCurrently())
GoOutFullscreen();
else
GoInFullscreen($("#demo-element").get(0));
});
$(document).on('fullscreenchange webkitfullscreenchange mozfullscreenchange MSFullscreenChange', function() {
if(IsFullScreenCurrently()) {
$("#demo-element span").text('Full Screen Mode Enabled');
$("#go-button").text('Disable Full Screen');
}
else {
$("#demo-element span").text('Full Screen Mode Disabled');
$("#go-button").text('Enable Full Screen');
}
});</script>

这里有一个完整的解决方案，以进入和退出全屏模式(即取消，退出，退出)
function cancelFullScreen() {
var el = document;
var requestMethod = el.cancelFullScreen||el.webkitCancelFullScreen||el.mozCancelFullScreen||el.exitFullscreen||el.webkitExitFullscreen;
if (requestMethod) { // cancel 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}");
}
}
}
function requestFullScreen(el) {
// 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}");
}
}
return false
}
function toggleFullScreen(el) {
if (!el) {
el = document.body; // Make the body go full screen.
}
var isInFullScreen = (document.fullScreenElement && document.fullScreenElement !== null) || (document.mozFullScreen || document.webkitIsFullScreen);
if (isInFullScreen) {
cancelFullScreen();
} else {
requestFullScreen(el);
}
return false;
}
如果你是在一个“售货亭”的情况下，一个进入全屏的Q&D方法是在浏览器窗口启动并运行后输入一个F11。这不是一个很好的开始，用户可能可以在顶部戳一个触摸屏，获得半全屏的视图，但在紧急情况下，或者只是为了开始一个项目，可以使用F11。
创建函数
function toggleFullScreen() {
if ((document.fullScreenElement && document.fullScreenElement !== null) ||
(!document.mozFullScreen && !document.webkitIsFullScreen)) {
$scope.topMenuData.showSmall = true;
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 {
$scope.topMenuData.showSmall = false;
if (document.cancelFullScreen) {
document.cancelFullScreen();
} else if (document.mozCancelFullScreen) {
document.mozCancelFullScreen();
} else if (document.webkitCancelFullScreen) {
document.webkitCancelFullScreen();
}
}
}
在Html中放代码像
<ul class="unstyled-list fg-white">
<li class="place-right" data-ng-if="!topMenuData.showSmall" data-ng-click="toggleFullScreen()">Full Screen</li>
<li class="place-right" data-ng-if="topMenuData.showSmall" data-ng-click="toggleFullScreen()">Back</li>
</ul>
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<h2>Fullscreen with JavaScript</h2>
<p>Click on the button to open the video in fullscreen mode.</p>
<button onclick="openFullscreen();">Open Video in Fullscreen Mode</button>
<p><strong>Tip:</strong> Press the "Esc" key to exit full screen.</p>
<video width="100%" controls id="myvideo">
<source src="rain.mp4" type="video/mp4">
<source src="rain.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>
<script>
var elem = document.getElementById("myvideo");
function openFullscreen() {
if (elem.requestFullscreen) {
elem.requestFullscreen();
} else if (elem.webkitRequestFullscreen) { /* Safari */
elem.webkitRequestFullscreen();
} else if (elem.msRequestFullscreen) { /* IE11 */
elem.msRequestFullscreen();
}
}
</script>
<p>Note: Internet Explorer 10 and earlier versions do not support the msRequestFullscreen() method.</p>
</body>
