h5+js如何实现视频播放？简单视频播放器控件的制作

h5+js如何实现视频播放？本篇文章就给大家通过示例介绍使用h5+js制作视频播放器控件的方法，有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。【推荐教程：Html5视频教程】

由于h5兼容性问题，很多浏览器对于插入视频播放的支持都大不相同。火狐支持的比较完整，谷歌则支持的不是很好，很多功能都不能实现，这就需要我们去自制一个播放界面，去兼容不同的浏览器。

只插入一个视频时，浏览器中只会出现这样一个画面。只有单击右键才可以弹出菜单栏显示播放或者显示控件；

下面是一个自制播放控件的小练习，比较粗糙，很多功能有待完善。

制作中可能用到的一些常见属性和内容：

1、标签39000f942b2545a5315c57fa3276f220a6a9c6d3f311dabb528ad355798dc27d

2、常用属性：

autoplay--自动播放；

controls--显示音乐控件；

loop--实现循环播放；

poster--视频加载未开始时播放的图片；

3、video支持多视频格式：（以此解决不同浏览器对视频格式的兼容问题）

<video poster="img/oceans-clip.png">
    <source src="video/oceans-clip.mp4"></source> 
    <source src="video/oceans-clip.webm"></source> 
    <source src="video/oceans-clip.ogv"></source> 
</video>

4、获取当前视频播放的状态：

playbtn(对象).onclick=function(){
　　　if(video.paused){
　　　  video.play();　　
　　　}else{
　　　　video.pause();
　　　}
}

5、视频的一些特殊事件：

1）当视频可以播放获取总时间：

vdideo.oncanplay=function(){
　　　console.log(video.duration);
}

2）视频播放时，获取实时时间：

video.ontimedate=function(){
　　console.log(video.currentTime);
}

3）视频结束：

video.onended=function(){
}

 实现后的样式：
