我想要得到v=id从YouTube的URL与JavaScript(没有jQuery，纯JavaScript)。
YouTube URL格式示例
http://www.youtube.com/watch?v=u8nQa1cJyX8&a=GxdCwVVULXctT2lYDEPllDR0LRTutYfW
http://www.youtube.com/watch?v=u8nQa1cJyX8
或在URL中包含视频ID的任何其他YouTube格式。
这些格式的结果

这里有一个红宝石版本:
def youtube_id(url)
# Handles various YouTube URLs (youtube.com, youtube-nocookie.com, youtu.be), as well as embed links and urls with various parameters
regex = /(?:youtube(?:-nocookie)?\.com\/(?:[^\/\n\s]+\/\S+\/|(?:v|vi|e(?:mbed)?)\/|\S*?[?&]v=|\S*?[?&]vi=)|youtu\.be\/)([a-zA-Z0-9_-]{11})/
match = regex.match(url)
if match && !match[1].nil?
match[1]
else
nil
end
end
测试方法:
example_urls = [
'www.youtube-nocookie.com/embed/dQw4-9W_XcQ?rel=0',
'http://www.youtube.com/user/Scobleizer#p/u/1/dQw4-9W_XcQ',

其他回答
这是一个稍作改动的版本:
var regExp = /^.*(youtu.be\/|v\/|u\/\w\/|embed\/|watch\?v=|\&v=)([^#\&\?]{11,11}).*/;
var match = url.match(regExp);
if (match) if (match.length >= 2) return match[2];
// error
这假设代码总是11个字符。 我在ActionScript中使用这个，不确定在Javascript中是否支持{11,11}。还增加了对&v=....的支持(以防万一)
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。

你可以点击共享按钮并复制缩短URL。 例如: 这个YouTube视频的网址是https://www.youtube.com/watch?v=3R0fzCw3amM 但如果你点击分享按钮并复制缩短URL，你会得到这个https://youtu.be/3R0fzCw3amM
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]);
这里有一个红宝石版本:
def youtube_id(url)
# Handles various YouTube URLs (youtube.com, youtube-nocookie.com, youtu.be), as well as embed links and urls with various parameters
regex = /(?:youtube(?:-nocookie)?\.com\/(?:[^\/\n\s]+\/\S+\/|(?:v|vi|e(?:mbed)?)\/|\S*?[?&]v=|\S*?[?&]vi=)|youtu\.be\/)([a-zA-Z0-9_-]{11})/
match = regex.match(url)
if match && !match[1].nil?
match[1]
else
nil
end
end
