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;
