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。

这是JavaScript中最接近全屏的效果:
<script type="text/javascript">
window.onload = maxWindow;
function maxWindow() {
window.moveTo(0, 0);
if (document.all) {
top.window.resizeTo(screen.availWidth, screen.availHeight);
}
else if (document.layers || document.getElementById) {
if (top.window.outerHeight < screen.availHeight || top.window.outerWidth < screen.availWidth) {
top.window.outerHeight = screen.availHeight;
top.window.outerWidth = screen.availWidth;
}
}
}
</script>
幸运的是，对于毫无戒心的网络用户来说，这不能用javascript完成。你需要编写特定于浏览器的插件，如果它们还不存在的话，然后以某种方式让人们下载它们。你能得到的最接近的是一个最大化的窗口，没有工具或导航栏，但用户仍然能够看到url。
窗口.open(“http://www.wege.com”，“标题”，“类型”=fullWindow, fullscreen, scrollbars=yes);“>
这通常被认为是不好的做法，因为它从用户那里删除了很多浏览器功能。
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>
函数f () {plr.requestFullscreen (); document.exitFullscreen ()};plr.requestFullscreen():document.exitFullscreen()}
<!DOCTYPE html><html><head>
<style>
body{background:#000}
#plr{position:relative;background:#fff;width:360px}
#vd{width:100%;background:grey}
button{width:48px;height:48px;border:0;background:grey}
</style>
</head><body>
<div id="plr">
<video id="vd" src="video.mp4"></video>
<button onclick="(plr.offsetWidth==360)?plr.requestFullscreen():document.exitFullscreen()">fs</button>
<button onclick="plr.requestFullscreen();document.exitFullscreen()">fs2</button>
</div>
</body></html>
以下是我对全屏和退出全屏的完整解决方案(非常感谢上面塔的回答):
$(document).ready(function(){
$.is_fs = false;
$.requestFullScreen = function(calr)
{
var element = document.body;
// Supports most browsers and their versions.
var requestMethod = element.requestFullScreen || element.webkitRequestFullScreen || element.mozRequestFullScreen || element.msRequestFullScreen;
if (requestMethod) { // Native full screen.
requestMethod.call(element);
} else if (typeof window.ActiveXObject !== "undefined") { // Older IE.
var wscript = new ActiveXObject("WScript.Shell");
if (wscript !== null) {
wscript.SendKeys("{F11}");
}
}
$.is_fs = true;
$(calr).val('Exit Full Screen');
}
$.cancel_fs = function(calr)
{
var element = document; //and NOT document.body!!
var requestMethod = element.exitFullScreen || element.mozCancelFullScreen || element.webkitExitFullScreen || element.mozExitFullScreen || element.msExitFullScreen || element.webkitCancelFullScreen;
if (requestMethod) { // Native full screen.
requestMethod.call(element);
} else if (typeof window.ActiveXObject !== "undefined") { // Older IE.
var wscript = new ActiveXObject("WScript.Shell");
if (wscript !== null) {
wscript.SendKeys("{F11}");
}
}
$(calr).val('Full Screen');
$.is_fs = false;
}
$.toggleFS = function(calr)
{
$.is_fs == true? $.cancel_fs(calr):$.requestFullScreen(calr);
}
});
// 调用:
<input type="button" value="Full Screen" onclick="$.toggleFS(this);" />
