video获取视频的时间长度是获取的到的值是无穷大（Infinity），

Question

<video id="video" preload="auto">                            
    <source src="./static/video/movie.ogg" type="video/ogg"> 
</video>                                                     
下面是JS获取duration和currentTime，前者是无穷大，后者报错，没有curretTime属性
var length = e.pageX - $('#progressWrap').offset().left; 
var percent = length / progressWrap.offsetWidth;         
playProgress.style.width =percent*410+ "px";             
video.pause();                                           
video.currentTime =Math.ceil( percent * video.duration); 
video.play();                                            
progressFlag = setInterval(getProgress, 60);             

Answer 1

可能是视频没加载好...

video.oncanplay = function () {
  ...
}
