篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了网页中视频自动播放的代码相关的知识，希望对你有一定的参考价值。

偶用的代码如下：

<OBJECT id=Player height=150 width=260
classid=clsid:CFCDAA03-8BE4-11CF-B84B-0020AFBBCCFA
viewastext>
<PARAM NAME="_ExtentX" VALUE="12726">
<PARAM NAME="_ExtentY" VALUE="8520">
<PARAM NAME="AUTOSTART" VALUE="0">
<PARAM NAME="SHUFFLE" VALUE="0">
<PARAM NAME="PREFETCH" VALUE="0">
<PARAM NAME="NOLABELS" VALUE="0">
<PARAM NAME="CONTROLS" VALUE="ImageWindow">
<PARAM NAME="CONSOLE" VALUE="_master">
<PARAM NAME="LOOP" VALUE="0">
<PARAM NAME="NUMLOOP" VALUE="0">
<PARAM NAME="CENTER" VALUE="0">
<PARAM NAME="MAINTAINASPECT" VALUE="sp/01.rmvb">
<PARAM NAME="BACKGROUNDCOLOR" VALUE="#000000">
</OBJECT>
<OBJECT id=Player height=50 width=260
classid=clsid:CFCDAA03-8BE4-11CF-B84B-0020AFBBCCFA
viewastext>
<PARAM NAME="_ExtentX" VALUE="18256">
<PARAM NAME="_ExtentY" VALUE="794">
<PARAM NAME="AUTOSTART" VALUE="-1">
<PARAM NAME="SHUFFLE" VALUE="0">
<PARAM NAME="PREFETCH" VALUE="0">
<PARAM NAME="NOLABELS" VALUE="0">
<PARAM NAME="CONTROLS" VALUE="controlpanel">
<PARAM NAME="CONSOLE" VALUE="_master">
<PARAM NAME="LOOP" VALUE="0">
<PARAM NAME="NUMLOOP" VALUE="0">
<PARAM NAME="CENTER" VALUE="0">
<PARAM NAME="MAINTAINASPECT" VALUE="0">
<PARAM NAME="BACKGROUNDCOLOR" VALUE="#000000">
<PARAM NAME="SRC" VALUE="sp/01.rmvb">
</OBJECT>

以前可以播放，后来不能播放了，不知道是什么原因，是服务器安全设置的问题还是代码的问题呢？（中间服务器重装过一次）

代码和视频文件都没有改的。

HTML5中的video和audio标签中有一个autoplay属性,添加这个属性后就会在文件加载完成以后自动播放。具体代码如下: video: audio。

构成

文字与图片是构成一个网页的两个最基本的。

元素。你可以简单地理解为：文字，就是网页的内容。图片，就是网页的美观。除此之外，网页的元素还包括动画、音乐、程序等等。

在网页上点击鼠标右键，选择菜单中的 “查看源文件” ，就可以通过记事本看到网页的实际内容。可以看到网页实际上只是一个纯文本文件。它通过各式各样的标记对页面上的文字、图片、表格、声音等元素进行描述（例如字体、颜色、大小），而浏览器则对这些标记进行解释并生成页面。

于是就得到你现在所看到的画面。为什么在源文件看不到任何图片？网页文件中存放的只是图片的链接位置，而图片文件与网页文件是互相独立存放的，甚至可以不在同一台计算机上。

网页通常有以下元素：

文字资料图像档案Applet（在页面内执行的副程式）超链结网页的合成体为网站，一个网站的开始点为首页。

记录功能

当你每次上网时，都会在历史记录里留下记录，并且被保存在浏览器的缓存文件夹里，删除时只要右键删除就可以了。

在嵌入式 YouTube 播放器中自动播放下一个视频

【中文标题】在嵌入式 YouTube 播放器中自动播放下一个视频【英文标题】：Autoplay next video in embedded YouTube player 【发布时间】：2016-07-03 07:13:05 【问题描述】：

YouTube 上有一个自动播放功能，可以播放下一个推荐的视频。

如何在嵌入式 YouTube 播放器中启用此功能？

YouTube API here 解释了自动播放功能，但这并不相同。他们描述的功能是在网页加载后自动播放视频。

有没有办法在嵌入的视频帧中实现 YouTube 上的自动播放功能？

【问题讨论】：

问题可能重复。这可能会有所帮助：***.com/questions/19725950/… 【参考方案1】：

<iframe   src="https://www.youtube.com/embed/211t6r12XPQ" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen>
</iframe>

也许这是某个网站的 AI 或 UI 复制链接

【讨论】：

【参考方案2】：

根据 youtube api 参考页面https://developers.google.com/youtube/iframe_api_reference中列出的选项

没有任何特定选项可以启用您正在寻找的功能。

但是，您可以通过其他方法来实现这一点，使嵌入式 youtube 视频播放器自动播放下一个视频。

为此，您必须从播放列表嵌入视频，而不是直接嵌入视频

<iframe   src="https://www.youtube.com/embed/NTM4kxNjAIY?list=PLelK7aEMtfK2wpv7tv472alrDpNwO_0jw" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

【讨论】：

【参考方案3】：

据我了解，这个想法是使用嵌入式 youtube (YouTube Iframe-API) 与使用普通 youtube.com 的行为相同，并将自动播放设置为 true。

到目前为止，我发现的唯一方法是通过 api 调用获取 videoId，如下所述：https://***.com/a/19732072/10956686 然后在 PlayerState.ENDED 事件触发后使用 player.loadVideoById()。

    function onPlayerStateChange(event)      
        if (event.data == YT.PlayerState.ENDED && !done)         
            player.loadVideoById(myFetchedNextVideoId);

但这可能会导致大量 API 配额的使用。
