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
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。

这个函数非常好用
function toggle_full_screen()
{
if ((document.fullScreenElement && document.fullScreenElement !== null) || (!document.mozFullScreen && !document.webkitIsFullScreen))
{
if (document.documentElement.requestFullScreen){
document.documentElement.requestFullScreen();
}
else if (document.documentElement.mozRequestFullScreen){ /* Firefox */
document.documentElement.mozRequestFullScreen();
}
else if (document.documentElement.webkitRequestFullScreen){ /* Chrome, Safari & Opera */
document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
}
else if (document.msRequestFullscreen){ /* IE/Edge */
document.documentElement.msRequestFullscreen();
}
}
else
{
if (document.cancelFullScreen){
document.cancelFullScreen();
}
else if (document.mozCancelFullScreen){ /* Firefox */
document.mozCancelFullScreen();
}
else if (document.webkitCancelFullScreen){ /* Chrome, Safari and Opera */
document.webkitCancelFullScreen();
}
else if (document.msExitFullscreen){ /* IE/Edge */
document.msExitFullscreen();
}
}
}
要使用它，只需调用:
toggle_full_screen();
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;
}
你能试试吗:
<script type="text/javascript"> 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(); } } </script> <a href="#" onClick="go_full_screen();">Full Screen / Compress Screen</a>
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。
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>
