最近在做一个项目,要求监控视频的播放事件并能够打印LOG日志,经过一番思索,使用javascript实现了此功能,代码如下:
HTML:
<!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <title>Multi Source</title> </head> <body> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> <video src="http://www.w3school.com.cn/i/movie.mp4" controls autoplay></video> </body> </html>
JS:
<script type="text/javascript"> window.addEventListener("load",getVideoEvent); function getVideoEvent(){ var videoes=document.getElementsByTagName("video"); for (var i = 0; i < videoes.length; i++) { showEventLog("video"+(i+1),videoes[i]); } } function showEventLog(videoNum,Media){ eventTester = function(e){ Media.addEventListener(e,function(){ console.log(videoNum+":"+e); }); } eventTester("loadstart"); //客户端开始请求数据 eventTester("progress"); //客户端正在请求数据 eventTester("suspend"); //延迟下载 eventTester("abort"); //客户端主动终止下载(不是因为错误引起), eventTester("error"); //请求数据时遇到错误 eventTester("stalled"); //网速失速 eventTester("play"); //play()和autoplay开始播放时触发 eventTester("pause"); //pause()触发 eventTester("loadedmetadata"); //成功获取资源长度 eventTester("loadeddata"); // eventTester("waiting"); //等待数据,并非错误 eventTester("playing"); //开始回放 eventTester("canplay"); //可以播放,但中途可能因为加载而暂停 eventTester("canplaythrough"); //可以播放,歌曲全部加载完毕 eventTester("seeking"); //寻找中 eventTester("seeked"); //寻找完毕 eventTester("timeupdate"); //播放时间改变 eventTester("ended"); //播放结束 eventTester("ratechange"); //播放速率改变 eventTester("durationchange"); //资源长度改变 eventTester("volumechange"); //音量改变 } </script>
