video對象
兼容性寫法
<video controls> <source src="data/demo.ovg"> <source src="data/demo.mp4"> <source src="data/demo.webm"> 您的瀏覽器不支持，請升級您的瀏覽器 </video>
video 標簽 width height autoplay muted
poster帶有預覽圖（海報圖片）的視頻播放器
<video src='data/demo.mp4' muted controls autoplay height='400' width="200" poster='data/poster.jpg'></video>
選中video標簽
var VideoNode = document.getElementById('myVideo');src控制視頻的來源
VideoNode.src = 'data/demo.ogv';
手動設置控件 controls
VideoNode.controls = true;
設置視頻音量
VideoNode.volume = 0.5;
currentTime當前播放時間
快進效果
gogogo.onclick = function(){ VideoNode.currentTime = VideoNode.currentTime + 3; };暫停 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 視頻已經加載好 可以開始播放了
VideoNode.addEventListener('canplay',function(){ console.log('視頻已經加載好 可以開始播放了'); });requestFullscreen 讓video標簽變成全屏
VideoNode.webkitRequestFullscreen();VideoNode.mozRequestFullScreen(); fullScreenNode.onclick = function(){ if(VideoNode.webkitRequestFullscreen){ VideoNode.webkitRequestFullscreen(); } else if(VideoNode.mozRequestFullScreen){ VideoNode.mozRequestFullScreen(); } };volumechange 當音量更改時
VideoNode.onvolumechange = function(){ console.log('volumechange'); };聲音隨機更改
volumeNode.onclick = function(){ VideoNode.volume = Math.random(); };seeking 當用戶開始拖動進度條時 就會觸發的事件
var seekingNum = 0; VideoNode.onseeking = function(){ console.log('seeking...'); seekingNum++; seeking.innerHTML = seekingNum; };seeked 當用戶對視頻的進度條并且已經完成操作時會觸發的事件
var seekedNum = 0; VideoNode.onseeked = function(){ console.log('seeked...'); seekedNum++; seeked.innerHTML = seekedNum; };timeupdate監聽視頻播放的狀態
VideoNode.addEventListener('timeupdate',function(){ // 總時長，以分鐘：秒的形式顯示 let allTime = parseInt(VideoNode.duration/60)+':'+parseInt(VideoNode.duration%60); // 當前時間，以分鐘：秒的形式顯示 let nowTime = parseInt(VideoNode.currentTime/60)+':'+parseInt(VideoNode.currentTime%60); timeNode.innerHTML = nowTime+'/'+allTime; })readyState 視頻的準備信息
console.log(VideoNode.readyState); setTimeout(function(){ console.log(VideoNode.readyState); },500);playbackRate 查看或設置視頻的一個播放速度
console.log(VideoNode.playbackRate)
Rate設置倍速
//Rate設置0.5倍速 RateNode.children[0].onclick = function(){ VideoNode.playbackRate = 0.5; }; //Rate設置1倍速 RateNode.children[1].onclick = function(){ VideoNode.playbackRate = 1; }; //Rate設置2倍速 RateNode.children[2].onclick = function(){ VideoNode.playbackRate = 2; };loop的設置
loopNode.onclick = function(){ if(VideoNode.loop == false){ this.innerHTML = '循環'; VideoNode.loop = true; } else{ this.innerHTML = '不循環'; VideoNode.loop = false; } };src返回的數據
console.log('src='+VideoNode.src);
currentSrc返回的數據
console.log('currentSrc='+VideoNode.currentSrc);
監聽ended事件
VideoNode.addEventListener('ended',function(){ console.log('視頻播放結束了'); VideoNode.play(); })查看視頻的網絡狀態
console.log(VideoNode.networkState)
手動設置控件 controls
VideoNode.controls = true;
手動設置靜音 muted
VideoNode.muted = true;
