判断视频是否在Javascript中加载 [英] Tell whether video is loaded or not in Javascript

问题描述

因此，我一直在使用
$ b

So, I've been using a listener on

document.getElementById("video").buffered.length

查看它是否大于 0 一个视频的加载与否。这适用于非常小的视频，仅适用于Google Chrome。它根本不适用于Firefox。任何想法如何让这个工作？

to see if it's greater than 0 for when a video's loaded or not. This works for a very small video, and only in Google Chrome. It doesn't work in Firefox at all. Any ideas for how to get this to work?

我基本上要等到加载3个单独的视频才能采取具体行动，我该怎么做？

I essentially want to wait till 3 seperate videos are loaded to take a specific action, how do I go about this?

推荐答案

试试这个：

Try this:

var video = document.getElementById("video-id-name");

if ( video.readyState === 4 ) {
    // it's loaded
}
