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
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;
