直接上代碼：

全屏

function fullScreen() {var el = document.documentElement;var rfs = el.requestFullScreen || el.webkitRequestFullScreen || el.mozRequestFullScreen || el.msRequestFullScreen;if(typeof rfs != "undefined" && rfs) {rfs.call(el);} else if(typeof window.ActiveXObject != "undefined") {//for IE，這里其實就是模擬了按下鍵盤的F11，使瀏覽器全屏var wscript = new ActiveXObject("WScript.Shell");if(wscript != null) {wscript.SendKeys("{F11}");}} } ```退出全屏```javascript function exitFullScreen() {var el = document;var cfs = el.cancelFullScreen || el.webkitCancelFullScreen || el.mozCancelFullScreen || el.exitFullScreen;if(typeof cfs != "undefined" && cfs) {cfs.call(el);} else if(typeof window.ActiveXObject != "undefined") {//for IE，這里和fullScreen相同，模擬按下F11鍵退出全屏var wscript = new ActiveXObject("WScript.Shell");if(wscript != null) {wscript.SendKeys("{F11}");}} }
