如何使用Javascript使窗口全屏显示（在整个屏幕上展开）

如何以与IE，Firefox和Opera兼容的方式使用JavaScript使访问者的浏览器全屏显示？

这与您使用JavaScript进入全屏显示的时间非常接近：

<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> 

在较新的浏览器中，例如Chrome 15，Firefox 10，Safari 5.1，IE 10，这是可能的。对于旧版IE，也可以通过ActiveX进行浏览，具体取决于它们的浏览器设置。

方法如下：

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);

显然，用户显然需要首先接受全屏请求，并且无法在页面加载时自动触发此请求，它需要由用户（例如按钮）触发

此代码还包括如何为Internet Explorer 9（可能是较旧的版本）以及最新版本的Google Chrome启用全屏显示。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}");
  }
}

这是进入和退出全屏模式（即取消，退出，转义）的完整解决方案

        function cancelFullScreen(el) {
            var requestMethod = el.cancelFullScreen||el.webkitCancelFullScreen||el.mozCancelFullScreen||el.exitFullscreen;
            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 toggleFull() {
            var elem = document.body; // Make the body go full screen.
            var isInFullScreen = (document.fullScreenElement && document.fullScreenElement !== null) ||  (document.mozFullScreen || document.webkitIsFullScreen);

            if (isInFullScreen) {
                cancelFullScreen(document);
            } else {
                requestFullScreen(elem);
            }
            return false;
        }

您可以使用全屏API 您可以在此处查看示例

全屏API提供了一种使用用户整个屏幕呈现Web内容的简便方法。本文提供有关使用此API的信息。

全新的html5技术–全屏API为我们提供了一种以全屏模式展示网页内容的简便方法。我们将为您提供有关全屏模式的详细信息。只需想象一下使用此技术可获得的所有可能的优势–全屏相册，视频甚至游戏。

但是，在我们描述这项新技术之前，我必须注意，该技术是试验性的，并得到所有主要浏览器的支持。

您可以在此处找到完整的教程： http : //www.css-jquery-design.com/2013/11/javascript-jquery-fullscreen-browser-window-html5-technology/

这是工作示例： http : //demo.web3designs.com/javascript-jquery-fullscreen-browser-window-html5-technology.htm

我已经用过了...

<!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 -->

</html>

来自以下示例的简单示例：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>

创建功能

function toggleFullScreen() {

            if ((document.fullScreenElement && document.fullScreenElement !== null) ||
                    (!document.mozFullScreen && !document.webkitIsFullScreen)) {
             $scope.topMenuData.showSmall = true;
                if (document.documentElement.requestFullScreen) {
                    document.documentElement.requestFullScreen();
                } else if (document.documentElement.mozRequestFullScreen) {
                    document.documentElement.mozRequestFullScreen();
                } else if (document.documentElement.webkitRequestFullScreen) {
                    document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
                }
            } else {

                  $scope.topMenuData.showSmall = false;
                if (document.cancelFullScreen) {
                    document.cancelFullScreen();
                } else if (document.mozCancelFullScreen) {
                    document.mozCancelFullScreen();
                } else if (document.webkitCancelFullScreen) {
                    document.webkitCancelFullScreen();
                }
            }
        }

在HTML把代码像

<ul class="unstyled-list fg-white">

            <li class="place-right" data-ng-if="!topMenuData.showSmall" data-ng-click="toggleFullScreen()">Full Screen</li>
            <li class="place-right" data-ng-if="topMenuData.showSmall" data-ng-click="toggleFullScreen()">Back</li>
        </ul>

现在，全屏API越来越普及并且日趋成熟，为什么不尝试Screenfull.js呢？昨天我第一次使用它，今天我们的应用程序在（几乎）所有浏览器中都变为全屏显示！

确保将其与:fullscreenCSS中的伪类耦合。有关更多信息，请参见https://www.sitepoint.com/use-html5-full-screen-api/。

幸运的是，对于毫无戒心的Web用户，这不能仅使用javascript来完成。如果尚不存在特定于浏览器的插件，则需要编写它们，然后以某种方式让人们下载它们。您可以得到的最接近的是没有工具或导航栏的最大化窗口，但用户仍然可以看到该URL。

window.open('http://www.web-page.com', 'title' , 'type=fullWindow, fullscreen, scrollbars=yes');">

尽管这会删除用户的许多浏览器功能，但通常认为这是不好的做法。

尝试screenfull.js。这是一个很好的跨浏览器解决方案，也应该适用于Opera浏览器。

用于JavaScript全屏API的跨浏览器使用的简单包装，使您可以将页面或任何元素置于全屏状态。消除浏览器实现上的差异，因此您不必这样做。

        <script type="text/javascript">
            function max()
            {
               window.open("", "_self", "fullscreen=yes, scrollbars=auto"); 
            }
        </script>

        <div>
        This is Test Page
        </div>
        </form>
    </body>
    </html>

你能试一下吗：

<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>

试试这个脚本

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

要从脚本调用，请使用以下代码，

window.fullScreen('fullscreen.jsp');

或与超链接一起使用

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

在Firefox 10中，您可以使用以下JavaScript将当前页面设置为全屏显示（没有窗口镶边的全屏显示）：

window.fullScreen = true;

这样可以全屏显示窗口

注意： 要使此方法起作用，您需要从http://code.jquery.com/jquery-2.1.1.min.js进行查询

或者使像这样的javascript链接。

<script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>

   <div id="demo-element">
        <span>Full Screen Mode Disabled</span>
        <button id="go-button">Enable Full Screen</button>
    </div>
    <script>
    function GoInFullscreen(element) {
        if(element.requestFullscreen)
            element.requestFullscreen();
        else if(element.mozRequestFullScreen)
            element.mozRequestFullScreen();
        else if(element.webkitRequestFullscreen)
            element.webkitRequestFullscreen();
        else if(element.msRequestFullscreen)
            element.msRequestFullscreen();
    }

    function GoOutFullscreen() {
        if(document.exitFullscreen)
            document.exitFullscreen();
        else if(document.mozCancelFullScreen)
            document.mozCancelFullScreen();
        else if(document.webkitExitFullscreen)
            document.webkitExitFullscreen();
        else if(document.msExitFullscreen)
            document.msExitFullscreen();
    }

    function IsFullScreenCurrently() {
        var full_screen_element = document.fullscreenElement || document.webkitFullscreenElement || document.mozFullScreenElement || document.msFullscreenElement || null;

        if(full_screen_element === null)
            return false;
        else
            return true;
    }

    $("#go-button").on('click', function() {
        if(IsFullScreenCurrently())
            GoOutFullscreen();
        else
            GoInFullscreen($("#demo-element").get(0));
    });

    $(document).on('fullscreenchange webkitfullscreenchange mozfullscreenchange MSFullscreenChange', function() {
        if(IsFullScreenCurrently()) {
            $("#demo-element span").text('Full Screen Mode Enabled');
            $("#go-button").text('Disable Full Screen');
        }
        else {
            $("#demo-element span").text('Full Screen Mode Disabled');
            $("#go-button").text('Enable Full Screen');
        }
    });</script>

如果您处于“信息亭”状态，则进入全屏的Q＆D方式是在启动并运行F11后将F11馈入浏览器窗口。这并不是一个很好的启动方式，用户也许可以在顶部拨动触摸屏并获得半全屏视图，但是提供F11可能只是紧要关头，或者仅仅是开始一个项目。

这里是我的完整的解决方案Full Screen和Exit Full Screen两个（非常感谢帮助从塔的回答以上）：

$(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);
}

});

//通话：

<input type="button" value="Full Screen" onclick="$.toggleFS(this);" />
