这期内容当中小编将会给大家带来有关怎么在HTML5中自定义一个视频播放器，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。
video对象
兼容性写法
<video controls> <source src="data/demo.ovg"> <source src="data/demo.mp4"> <source src="data/demo.WEBm"> 您的浏览器不支持，请升级您的浏览器 </video>video 标签 width height autoplay muted
poster带有预览图（海报图片）的视频播放器
<video src='data/demo.mp4' muted controls autoplay height='400' width="200" poster='data/poster.jpg'></video>选中video标签
var Videonode = document.getElementById('myVideo');src控制视频的来源
VideoNode.src = 'data/demo.ogv';手动设置控件 controls
VideoNode.controls = true;设置视频音量
VideoNode.volume = 0.5;currentTime当前播放时间
快进效果
Gogogo.onclick = function(){ VideoNode.currentTime = VideoNode.currentTime + 3; };暂停 pause()
stopNode.onclick = function(){ VideoNode.pause(); };播放play()
playNode.onclick = function(){ VideoNode.play(); };load 刷新播放器的事件
reloadNode.onclick = function(){ VideoNode.src = 'data/demo.mp4'; VideoNode.load(); };canplay 视频已经加载好 可以开始播放了
VideoNode.addEventListener('canplay',function(){ console.log('视频已经加载好 可以开始播放了'); });requestFullscreen 让video标签变成全屏
VideoNode.webkitRequestFullscreen();VideoNode.mozRequestFullScreen(); fullScreenNode.onclick = function(){ if(VideoNode.webkitRequestFullscreen){ VideoNode.webkitRequestFullscreen(); } else if(VideoNode.mozRequestFullScreen){ VideoNode.mozRequestFullScreen(); } };volumechange 当音量更改时
VideoNode.onvolumechange = function(){ console.log('volumechange'); };声音随机更改
volumeNode.onclick = function(){ VideoNode.volume = Math.random(); };seeking 当用户开始拖动进度条时 就会触发的事件
var seekingNum = 0; VideoNode.onseeking = function(){ console.log('seeking...'); seekingNum++; seeking.innerhtml = seekingNum; };seeked 当用户对视频的进度条并且已经完成操作时会触发的事件
var seekedNum = 0; VideoNode.onseeked = function(){ console.log('seeked...'); seekedNum++; seeked.innerHTML = seekedNum; };timeupdate监听视频播放的状态
VideoNode.addEventListener('timeupdate',function(){ // 总时长，以分钟：秒的形式显示 let allTime = parseInt(VideoNode.duration/60)+':'+parseInt(VideoNode.duration%60); // 当前时间，以分钟：秒的形式显示 let nowTime = parseInt(VideoNode.currentTime/60)+':'+parseInt(VideoNode.currentTime%60); timeNode.innerHTML = nowTime+'/'+allTime; })readyState 视频的准备信息
console.log(VideoNode.readyState); setTimeout(function(){ console.log(VideoNode.readyState); },500);playbackRate 查看或设置视频的一个播放速度
console.log(VideoNode.playbackRate)Rate设置倍速
//Rate设置0.5倍速 RateNode.children[0].onclick = function(){ VideoNode.playbackRate = 0.5; }; //Rate设置1倍速 RateNode.children[1].onclick = function(){ VideoNode.playbackRate = 1; }; //Rate设置2倍速 RateNode.children[2].onclick = function(){ VideoNode.playbackRate = 2; };loop的设置
loopNode.onclick = function(){ if(VideoNode.loop == false){ this.innerHTML = '循环'; VideoNode.loop = true; } else{ this.innerHTML = '不循环'; VideoNode.loop = false; } };src返回的数据
console.log('src='+VideoNode.src);
currentSrc返回的数据
console.log('currentSrc='+VideoNode.currentSrc);
监听ended事件
VideoNode.addEventListener('ended',function(){ console.log('视频播放结束了'); VideoNode.play(); })查看视频的网络状态
console.log(VideoNode.networkState)
手动设置控件 controls
VideoNode.controls = true;
手动设置静音 muted
VideoNode.muted = true;
自定义视频播放器
