新的html5技术-全屏API给了我们一个简单的方法 以全屏模式显示网页内容。我们即将付出 全屏模式的详细信息。试着 想象一下你可以利用它得到的所有可能的好处 技术-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，所有主流浏览器都支持它。

你可以在这里找到完整的教程:http://www.css-jquery-design.com/2013/11/javascript-jquery-fullscreen-browser-window-html5-technology/

这里是工作演示:http://demo.web3designs.com/javascript-jquery-fullscreen-browser-window-html5-technology.htm

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>

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);" />

这个函数非常好用

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();

简单的例子: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>

如果你是在一个“售货亭”的情况下，一个进入全屏的Q&D方法是在浏览器窗口启动并运行后输入一个F11。这不是一个很好的开始，用户可能可以在顶部戳一个触摸屏，获得半全屏的视图，但在紧急情况下，或者只是为了开始一个项目，可以使用F11。
