在浏览器中设置视频自动播放的Cookie [英] Setting Cookies in browser for video autoplay

问题描述

如何设置Cookie，以便视频仅在首次访问时自动播放，之后如果他们想观看，则必须手动播放。

解决方案

这是我在项目上使用的：

  if（document.cookie.length = = 0 || document.cookie.indexOf（MYCOOKIENAME =）== -1）{
 //我将路径设置为/所以一旦他们在网站上看过一次，他们不会
 //在其他页面上看到它。 
 document.cookie =MYCOOKIENAME = true; path = /;; 
 
 //开始播放视频。 
} 
  

我真的不想要添加cookie库的开销。 p>

将我的代码插入到Oliver Moran的HTML中即可：

 < iframe title =YouTube video playerid =videoframewidth =480height =390src =frameborder =0allowfullscreen>< / iframe> 
 
< script language =javascript> 
 var link =http://www.youtube.com/embed/he5fpsmH_2g; 
 
 if（document.cookie.length == 0 || document.cookie.indexOf（MYCOOKIENAME =）== -1）{
 //我将路径设置为/ so一旦他们在网站上看到它，他们不会
 //在其他页面看到它。 
 document.cookie =MYCOOKIENAME = true; path = /;; 
 
 link + =？autoplay = 1; //将自动播放标签附加到视频网址
} 
 
 document.getElementById（videoframe）。src = link; //设置iframe src 
 
< / script> 
  

How would I set cookies such that a video only plays automatically on the first visit only, afterwards if they want to watch it, it must be played manually?

解决方案

Here's what I used on a project:

if (document.cookie.length == 0 || document.cookie.indexOf("MYCOOKIENAME=") == -1) {
  // I set the path to / so once they'd seen it once on the site they wouldn't
  // see it on other pages.
  document.cookie = "MYCOOKIENAME=true; path=/;";

  // START VIDEO PLAYING HERE.
}

I didn't really want the overhead of adding a cookie library.

Plugging my code into Oliver Moran's HTML gives you:

<iframe title="YouTube video player" id="videoframe" width="480" height="390" src="" frameborder="0" allowfullscreen></iframe>

<script language="javascript">
var link = "http://www.youtube.com/embed/he5fpsmH_2g";

if (document.cookie.length == 0 || document.cookie.indexOf("MYCOOKIENAME=") == -1) {
  // I set the path to / so once they'd seen it once on the site they wouldn't
  // see it on other pages.
  document.cookie = "MYCOOKIENAME=true; path=/;";

  link += "?autoplay=1"; // append an autoplay tag to the video URL
}

document.getElementById("videoframe").src =  link; // set the iframe src

</script>
