我使用这个代码,我学会了使浏览器全屏(它工作),但我试图修改它的版本以退出全屏失败.处理这些非标准API有点棘手,每个浏览器实现它有点不同.

这是代码：

// Bring the page into full-screen mode - Works!
function requestFullScreen(element) {

    // Supports most browsers and their versions.
    var requestMethod = element.requestFullScreen || 
        element.webkitRequestFullScreen           || 
        element.mozRequestFullScreen              || 
        element.msRequestFullScreen;
    if (requestMethod) {
        requestMethod.call(element);
    } else if ( typeof window.ActiveXObject !== "undefined") {
        var wscript = new ActiveXObject("WScript.Shell");
        if (wscript !== null) {
            wscript.SendKeys("{F11}");
        }
    }
}

// Exit fullscreen - Doesn't work!
function exitFullScreen(element){
    var requestMethod = element.exitFullscreen || 
        element.mozCancelFullScreen            || 
        element.webkitExitFullscreen           || 
        element.msExitFullscreen;
    if (requestMethod) {
        requestMethod();
    } else {
        console.log("Oops. Request method false.");
    }
}

电话：

var $fullscreenButton = $("#fullscreen-button");
var $smallscreenButton = $("#smallscreen-button");

$fullscreenButton.on("click",function() {
    var elem = document.body;

    // Make the body go full screen.
    requestFullScreen(elem);
});

$smallscreenButton.on("click",function() {
    var elem = document.body;

    // Exit full screen.
    exitFullScreen(elem);
});

exitFullScreen函数有什么问题？我该如何解决？

的jsfiddle：

虽然全屏请求功能通常在浏览器中适用于我,I could not get it to work in JSFiddle,我不确定这是因为我自己的错误,还是与JSFiddle有关.
