H5系列之video自己编写控制栏
2024-08-28 14:17:28
首先来了解一下 video， video呢，是H5 的标签，别人说的 H5播放器，没错 就是他了，利用video标签，可以实现视频播放。
但是啊，你会发现，在不同的浏览器上，播放器的 控制栏，都是不一样的。例如：
在不同的浏览器上， 显示不同的控制栏，这在公司开发，是绝对不允许出现的效果的。 所以，我们可以通过js控制video的方法，来进行自定义控制栏。
播放与暂停(video上面的方法，play() 和 pause())
效果图如下：
代码如下(有带注释)：

transform: translateY(-50%);

}
</style>
</head> <body> <div class="video_player">
<video src="./video/mda-jgsjz4gs2ipq6d8g.mp4"></video>
<div class="menu">
<div class="play">播放</div>
</div>
</div>
<script>var video = document.getElementsByTagName('video')[0];
var play = document.getElementsByClassName('play')[0]; play.onclick = function () {
if(video.paused){ //判断是否已经播放了，如果还没播放，返回true
video.play(); //触发方法，播放视频
play.innerHTML = "暂停"; //修改 文字。
}else{
video.pause(); //暂停播放。
play.innerHTML = "播放";
}
}
</script>
</body> </html>
添加时间( duration(视频总时长) 和 currentTime(当前播放到哪里的时间) )
代码如下：
<!DOCTYPE html>

}
.video_player video {
width: 100%;
height: 100%;
} .video_player .menu {

height: 50px;
background-color: rgba(0, 0, 0, 0.5);

display: none;
} .video_player .menu .play {

cursor: pointer;
} .time {

width: 100px;
height: 30px;

text-align: center;
line-height: 30px;
top: 50%;

transform: translateY(-50%);
}

</div>
</div>
<script> var video = document.getElementsByTagName('video')[0];
var play = document.getElementsByClassName('play')[0];
var time = document.getElementsByClassName('time')[0];
var timer = null;
play.onclick = function () {
if (video.paused) { //判断是否已经播放了，如果还没播放，返回true
video.play(); //触发方法，播放视频
play.innerHTML = "暂停"; //修改 文字。
} else {
video.pause(); //暂停播放。
play.innerHTML = "播放";
}
}
video.onloadedmetadata = function () {// 视频加载完成触发,然后我们把时间添加到time标签上去。
time.innerHTML = parseInt(video.currentTime / 60) + ":" + parseInt(video.currentTime % 60) + "/" + parseInt(video.duration / 60) + ":" + parseInt(video.duration % 60);
} setInterval(function () { //每隔 1秒，刷新一下时间。
time.innerHTML = parseInt(video.currentTime / 60) + ":" + parseInt(video.currentTime % 60) + "/" + parseInt(video.duration / 60) + ":" + parseInt(video.duration % 60);
}, 1000) </script>
</body> </html>
添加进度条，与点击跳转。(效果如下) 图片太大了，我删了几帧，所以看起来有点卡卡的。
代码如下：(如果发现你不能跳转，那么请看下浏览器的Response Headers 里面，如果你的http协议里面 只有 content-length 和 content-type 没有 content-Range: bytes 那么这个时候不允许 点击跳转(不能设置时间跳转))

最后还有几个属性：
autoplay =“autoplay” 自动播放
muted 静音播放
loop 循环播放
有些浏览器可能不支持MP4的视频格式，但一般会支持webm格式，所以为了兼容性，我们一般书写src在source元素里面 放上两个视频，支持哪个播放哪个
<video>
不在video元素书写src 在source元素书写，
<source src=".mp4">
<source src=".webm">
</video>
最后，代码可能有点乱，有需要的自己整理一下哈。
