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>

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)

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;

    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>
