h5+js视频播放器控件

   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<video></video>

    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:
