如何使用Javascript使窗口全屏(在屏幕上伸展)

Question

如何使用JavaScript以一种适用于IE,Firefox和Opera的方式使访问者的浏览器全屏显示？

Answer 1

在较新的浏览器中,例如Chrome 15,Firefox 10,Safari 5.1,IE 10,这是可能的.根据浏览器的设置,通过ActiveX也可以使用旧版IE.

这是怎么做的:

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,它需要由用户触发(例如,按钮)

此代码还包括如何为Internet Explorer 9以及可能的旧版本以及最新版本的Google Chrome启用全屏.接受的答案也可用于其他浏览器.

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}");
  }
}

• 如何通过JavaScript使用F11键事件使浏览器全屏显示

Answer 3

这与JavaScript中的全屏一样接近:

<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>

这是进入和退出全屏模式的完整解决方案(也就是取消,退出,退出)

        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;
        }

Answer 5

这个功能就像一个魅力

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();

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.

Answer 7

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>

全新的html5技术 -全屏API为我们提供了一种以全屏模式呈现网页内容的简便方法.我们即将为您提供有关全屏模式的详细信息.试着想象一下使用这项技术可以获得的所有优势 - 全屏相册,视频甚至游戏.

但在我们描述这项新技术之前,我必须指出这项技术是实验性的,并得到所有主要浏览器的支持.

简单的例子来自: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>

试试screenfull.js。这是一个很好的跨浏览器解决方案，应该也适用于 Opera 浏览器。

跨浏览器使用 JavaScript 全屏 API 的简单包装器，可让您将页面或任何元素全屏显示。消除浏览器实现差异，因此您不必这样做。

演示。

Answer 11

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 Put Code中

<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>
