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
screenfull.js试试。这是一个很好的跨浏览器解决方案，应该也适用于Opera浏览器。
JavaScript全屏API跨浏览器使用的简单包装器，它允许您将页面或任何元素显示为全屏。消除了浏览器实现的差异，所以您不必这样做。

简单的例子:http://www.longtailvideo.com/blog/26517/using-the-browsers-new-html5-fullscreen-capabilities/
<script type="text/javascript">
function goFullscreen(id) {
// Get the element that we want to take into fullscreen mode
var element = document.getElementById(id);
// These function will not exist in the browsers that don't support fullscreen mode yet,
// so we'll have to check to see if they're available before calling them.
if (element.mozRequestFullScreen) {
// This is how to go into fullscren mode in Firefox
// Note the "moz" prefix, which is short for Mozilla.
element.mozRequestFullScreen();
} else if (element.webkitRequestFullScreen) {
// This is how to go into fullscreen mode in Chrome and Safari
// Both of those browsers are based on the Webkit project, hence the same prefix.
element.webkitRequestFullScreen();
}
// Hooray, now we're in fullscreen mode!
}
</script>
<img class="video_player" src="image.jpg" id="player"></img>
<button onclick="goFullscreen('player'); return false">Click Me To Go Fullscreen! (For real)</button>
<!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>
</html>

您可以使用全屏API 你可以在这里看到一个例子
全屏API为web内容提供了一种简单的方式 使用用户的整个屏幕呈现。本文提供了 有关使用此API的信息。
我用过这个…
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<script language="JavaScript">
function fullScreen(theURL) {
window.open(theURL, '', 'fullscreen=yes, scrollbars=auto');
}
// End -->
</script>
</head>
<body>
<h1 style="text-align: center;">
Open In Full Screen
</h1>
<div style="text-align: center;"><br>
<a href="javascript:void(0);" onclick="fullScreen('http://google.com');">
Open Full Screen Window
</a>
</div>
</body>
</html>
