在 Javascript 中判断视频是否已加载 [英] Tell whether video is loaded or not in Javascript

问题描述

所以，我一直在

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

查看视频加载与否时它是否大于 0.这适用于非常小的视频，并且仅适用于 Google Chrome.它在 Firefox 中根本不起作用.有关如何使其工作的任何想法?

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?

我基本上想等到加载了 3 个单独的视频来执行特定操作，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:

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

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