这段代码还包括如何启用Internet Explorer 9的全屏，可能是更老的版本，以及最新版本的谷歌Chrome。接受的答案也可以用于其他浏览器。

var el = document.documentElement
    , rfs = // for newer Webkit and Firefox
           el.requestFullscreen
        || el.webkitRequestFullScreen
        || el.mozRequestFullScreen
        || el.msRequestFullscreen
;
if(typeof rfs!="undefined" && rfs){
  rfs.call(el);
} else if(typeof window.ActiveXObject!="undefined"){
  // for Internet Explorer
  var wscript = new ActiveXObject("WScript.Shell");
  if (wscript!=null) {
     wscript.SendKeys("{F11}");
  }
}

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>

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。

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);" />
