这个正则表达式匹配嵌入、共享和链接url。

const youTubeIdFromLink = (url) => url.match(/(?:https?:\/\/)?(?:www\.|m\.)?youtu(?:be)?\.(?:com|be)(?:\/watch\/?\?v=|\/embed\/|\/)([^\s&\?\/\#]+)/)[1];


console.log(youTubeIdFromLink('https://youtu.be/You-Tube_ID?rel=0&hl=en')); //You-Tube_ID

console.log(youTubeIdFromLink('https://www.youtube.com/embed/You-Tube_ID?rel=0&hl=en')); //You-Tube_ID

console.log(youTubeIdFromLink('https://m.youtube.com/watch?v=You-Tube_ID&rel=0&hl=en')); //You-Tube_ID

试试NPM包youtube-id

测试在不同的网址:

const tested = [
  'https://www.youtube.com/watch?v={YOUTUBE_ID}&nohtml5=False',
  'https://youtu.be/{YOUTUBE_ID}',
  'www.youtube.com/embed/{YOUTUBE_ID}'
  // ....
]

你可以使用下面的代码从URL中获取YouTube视频ID:

url = "https://www.youtube.com/watch?v=qeMFqkcPYcg"
VID_REGEX = /(?:youtube(?:-nocookie)?\.com\/(?:[^\/\n\s]+\/\S+\/|(?:v|e(?:mbed)?)\/|\S*?[?&]v=)|youtu\.be\/)([a-zA-Z0-9_-]{11})/
alert(url.match(VID_REGEX)[1]);

简单的正则表达式，如果你有完整的URL，保持简单。

results = url.match("v=([a-zA-Z0-9]+)&?")
videoId = results[1] // watch you need.

我做了一个小函数，从Youtube url中提取视频id，如下所示。

var videoId =函数(url) { Var match = url.match(/v=([0-9a-z_-]{1,20})/i); 返回(match ?匹配['1']:false); }; console.log (videoId (' https://www.youtube.com/watch?v=dQw4w9WgXcQ ')); console.log (videoId (' https://www.youtube.com/watch?t=17s&v=dQw4w9WgXcQ ')); console.log (videoId (' https://www.youtube.com/watch?v=dQw4w9WgXcQ&t=17s '));

这个函数将提取视频id，即使url中有多个参数。

我发现最好的解决方案(从2019年到2021年)是:

function YouTubeGetID(url){
   url = url.split(/(vi\/|v=|\/v\/|youtu\.be\/|\/embed\/)/);
   return (url[2] !== undefined) ? url[2].split(/[^0-9a-z_\-]/i)[0] : url[0];
}

我在这里找到的。
