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
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>

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>
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);" />
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();
在Firefox 10中,你可以使用以下javascript使当前页面全屏(没有窗口chrome的真正全屏):
window.fullScreen = true;
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>
