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:

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))
