或者让javascript链接像这样。

   <div id="demo-element">

    }

    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');
        }

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}");
  }
}

来源:

Chrome全屏API(请注意，然而 requestFullscreen“只工作在”“[m]大多数UIEvents和鼠标事件，如点击和按下键等”，“所以它不能被恶意使用”) 如何使浏览器全屏使用F11键事件通过JavaScript

创建函数

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中放代码像

<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>

既然全屏api越来越广泛，而且似乎越来越成熟，为什么不试试Screenfull.js呢?我昨天第一次使用它，今天我们的应用程序在(几乎)所有浏览器中真正全屏!

确保它与CSS中的:fullscreen伪类相结合。详见https://www.sitepoint.com/use-html5-full-screen-api/。

screenfull.js试试。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。

JavaScript全屏API跨浏览器使用的简单包装器，它允许您将页面或任何元素显示为全屏。消除了浏览器实现的差异，所以您不必这样做。

演示。
