| 标题 | HTML5 video播放器全屏(fullScreen)方法实例 |
| 范文 | 这篇文章主要介绍了HTML5 video播放器全屏(fullScreen)方法实例,本文直接给出一个完整代码实例,需要的朋友可以参考下 首先来说，这个标题具有误导性，但这样设置改标题也是主要因为video使用的比较多 在html5中，全屏方法可以适用于很多html 元素，不仅仅是video 代码如下: <!doctype html> <html> <head> <meta charset="utf-8" /> <title>全屏问题</title> <meta http-equiv="content-type" content="text/html; charset=utf-8"/> <meta http-equiv="imagetoolbar" content="no"/> <meta name="apple-mobile-web-app-capable" content="yes"/> <meta http-equiv="X-UA-Compatible" content="IE=Edge"> <style type="text/css"> *{ padding: 0px; margin: 0px; } body div.videobox{ width: 400px; height: 320px; margin: 100px auto; background-color:#000; } body div.videobox video.video { width: 100%; height: 100%; } :-webkit-full-screen { } :-moz-full-screen { } :-ms-fullscreen { } :-o-fullscreen { } :full-screen { } :fullscreen { } :-webkit-full-screen video { width: 100%; height: 100%; } :-moz-full-screen video{ width: 100%; height: 100%; } </style> </head> <body> <div id="videobox"> <video controls="controls" preload="preload" id="video" poster="poster.jpg"> <source src="./movie.ogg" type="video/ogg" /> <source src="./movie.mp4" type="video/mp4" /> <source src="./movie.webm" type="video/webm" /> <object data="./movie.mp4" height="100%"> <embed height="100%" src="./movie.swf" /> </object> </video> <button id="fullScreenBtn">全屏</button> </div> <script type="text/javascript"> //反射調用 var invokeFieldOrMethod = function(element, method) { var usablePrefixMethod; ["webkit", "moz", "ms", "o", ""].forEach(function(prefix) { if (usablePrefixMethod) return; if (prefix === "") { // 无前缀，方法首字母小写 method = method.slice(0,1).toLowerCase() + method.slice(1); } var typePrefixMethod = typeof element[prefix + method]; if (typePrefixMethod + "" !== "undefined") { if (typePrefixMethod === "function") { usablePrefixMethod = element[prefix + method](); } else { usablePrefixMethod = element[prefix + method]; } } }); return usablePrefixMethod; }; //進入全屏 function launchFullscreen(element) { //此方法不可以在異步任務中執行，否則火狐無法全屏 if(element.requestFullscreen) { element.requestFullscreen(); } else if(element.mozRequestFullScreen) { element.mozRequestFullScreen(); } else if(element.msRequestFullscreen){ element.msRequestFullscreen(); } else if(element.oRequestFullscreen){ element.oRequestFullscreen(); } else if(element.webkitRequestFullscreen) { element.webkitRequestFullScreen(); }else{ var docHtml = document.documentElement; var docBody = document.body; var videobox = document.getElementById('videobox'); var cssText = 'width:100%;height:100%;overflow:hidden;'; docHtml.style.cssText = cssText; docBody.style.cssText = cssText; videobox.style.cssText = cssText+';'+'margin:0px;padding:0px;'; document.IsFullScreen = true; } } //退出全屏 function exitFullscreen() { if (document.exitFullscreen) { document.exitFullscreen(); } else if (document.msExitFullscreen) { document.msExitFullscreen(); } else if (document.mozCancelFullScreen) { document.mozCancelFullScreen(); } else if(document.oRequestFullscreen){ document.oCancelFullScreen(); }else if (document.webkitExitFullscreen){ document.webkitExitFullscreen(); }else{ var docHtml = document.documentElement; var docBody = document.body; var videobox = document.getElementById('videobox'); docHtml.style.cssText = ""; docBody.style.cssText = ""; videobox.style.cssText = ""; document.IsFullScreen = false; } } document.getElementById('fullScreenBtn').addEventListener('click',function(){ launchFullscreen(document.getElementById('video')); window.setTimeout(function exit(){ //檢查瀏覽器是否處於全屏 if(invokeFieldOrMethod(document,'FullScreen') || invokeFieldOrMethod(document,'IsFullScreen') || document.IsFullScreen) { exitFullscreen(); } },5*1000); },false); </script> </body> </html> |
