视频加载后的jQuery加载功能 [英] jQuery load function after video loaded

问题描述

我有这样的HTML代码：

I have a HTML code like this:

... <video id="abc" preload="auto" autoplay="autoplay" loop="loop" webkit-playsinline="">
    <source src="3.mp4" type="video/mp4">
</video> ...

我使用了这个JS代码：

And I used this JS code:

$(document).ready(function () {
"use strict";


    $("#abc").load(function () {
        console.log(3);
    });
});

我想在视频加载时运行该功能。 JS代码适用于 img 标记，但不适用于 video 标记。我希望它像 img 标签一样工作。就像我希望它在从缓存加载视频时不运行。

我该怎么做？

I wanna run that function when the video loads. The JS code works with img tag but not with video tag. I want it to work like the img tag. Like I want it not to run when it loads videos from cache.
How can I do that?

推荐答案

HTML元素视频没有加载事件。它有其他，如 loadstart ， loadeddata 或 loadedmetadata 。查看此处可能的视频事件的完整列表。

HTML element video does not have load event. It has others, like loadstart, loadeddata or loadedmetadata. See a full list of possible viedo events here.

$("#abc").on("loadstart", function() {
  console.log(3);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<video id="abc" preload="auto" autoplay="autoplay" loop="loop" webkit-playsinline="">
  <source src="https://www.quirksmode.org/html5/videos/big_buck_bunny.mp4" type="video/mp4">
</video>

loadeddata ：当浏览器加载了音频/视频的当前帧时触发>
loadedmetadata ：当浏览器加载音频/视频的元数据时触发

loadstart ：浏览器开始查找时触发音频/视频

loadeddata: Fires when the browser has loaded the current frame of the audio/video
loadedmetadata: Fires when the browser has loaded meta data for the audio/video
loadstart: Fires when the browser starts looking for the audio/video
