 <button class="exit-fullscreen">退出全屏</button>
 <div class="div">
 <img class="img" src="images/a.png">
 </div>
</body>
<script>
 /* 调用示例 */
 // 窗口全屏
 $('.win-fullscreen').on('click', function() {
 requestFullScreen(document.documentElement);
 });

 // div全屏
 $('.div-fullscreen').on('click', function() {
 requestFullScreen($('.div')[0]);
 });

 // img全屏
 $('.img-fullscreen').on('click', function() {
 requestFullScreen($('.img')[0]);
 });

 // 退出全屏
 $('.exit-fullscreen').on('click', function() {
 exitFull();
 });

 // 窗口状态改变事件
 fullscreenchange(document, function(isFull) {
 console.log(isFull);
 });

 /* 封装 */
 // 窗口状态改变
 function fullscreenchange(el, callback) {
 el.addEventListener("fullscreenchange", function () { 
 callback && callback(document.fullscreen);
 }); 
 el.addEventListener("webkitfullscreenchange", function () { 
 callback && callback(document.webkitIsFullScreen);
 }); 
 el.addEventListener("mozfullscreenchange", function () { 
 callback && callback(document.mozFullScreen);
 }); 
 el.addEventListener("msfullscreenchange", function () { 
 callback && callback(document.msFullscreenElement);
 });
 }

 // 全屏
 function requestFullScreen(element) {
 var requestMethod = element.requestFullScreen || //W3C
 element.webkitRequestFullScreen || //Chrome等
 element.mozRequestFullScreen || //FireFox
 element.msRequestFullScreen; //IE11
 if (requestMethod) {
 requestMethod.call(element);
 }else if (typeof window.ActiveXObject !== "undefined") {//for Internet Explorer
 var wscript = new ActiveXObject("WScript.Shell");
 if (wscript !== null) {
 wscript.SendKeys("{F11}");
 }
 }
 }

 //退出全屏
 function exitFull() {
 var exitMethod = document.exitFullscreen || //W3C
 document.mozCancelFullScreen || //Chrome等
 document.webkitExitFullscreen || //FireFox
 document.webkitExitFullscreen; //IE11
 if (exitMethod) {
 exitMethod.call(document);
 }else if (typeof window.ActiveXObject !== "undefined") {//for Internet Explorer
 var wscript = new ActiveXObject("WScript.Shell");
 if (wscript !== null) {
 wscript.SendKeys("{F11}");
 }
 }
 }
