当浏览器不支持ogg格式时则显示“您的浏览器不支持 video 标签。”

执行如下:

 

如上图为视频设置一个默认图片。也可以添加其他属性。

controls/controls="controls" 显示播放按钮
autoplay/autoplay="autoplay" 立即播放
loop/loop="loop" 循环播放
muted/muted="muted" 静音
preload/preload="preload" 加载视频d
poster="路径" 显示默认图片

3、自定义播放暂停及大小(Video + DOM)

 
 

 

将javascript写在html的下方

function playPause()
{
   i f (myVideo.paused)
       myVideo.play();  //播放
   else
      myVideo.pause(); //暂停
}

function makeNormal()
{
    myVideo.width=420; //自定义宽度,高度自适应
}

执行如下:

 大多数浏览器支持的视频方法、属性和事件(日后在做理解)

方法 属性 事件
play() currentSrc play
pause() currentTime pause
load() videoWidth立即执行--视频元素前执行 progress
canPlayType() videoHeight立即执行--视频元素前执行 error
  duration timeupdate
  ended ended
  error abort
