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

在较新的浏览器中,如Chrome 15, Firefox 10, Safari 5.1, IE 10,这是可能的。根据浏览器设置,旧版本的IE也可以通过ActiveX实现。

以下是如何做到这一点:

function requestFullScreen(element) {
    // 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}");
        }
    }
}

var elem = document.body; // Make the body go full screen.
requestFullScreen(elem);

用户显然需要首先接受全屏请求,并且不可能在页面加载时自动触发此请求,它需要由用户触发(例如。一个按钮)

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;
        }

试试这个脚本

<script language="JavaScript">
function fullScreen(theURL) {
window.open(theURL, '', 'fullscreen=yes, scrollbars=auto' );
}
</script>

从脚本调用使用以下代码,

window.fullScreen('fullscreen.jsp');

或者用超链接使用这个

<a href="javascript:void(0);" onclick="fullScreen('fullscreen.jsp');"> 
Open in Full Screen Window</a>

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;

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>

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>
