我正在使用以下正则表达式来验证 YouTube 视频share url's.
var valid = /^(http\:\/\/)?(youtube\.com|youtu\.be)+$/;
alert(valid.test(url));
return false;
我希望正则表达式支持以下 URL 格式：
http://youtu.be/cCnrX1w5luM
http://youtube/cCnrX1w5luM
www.youtube.com/cCnrX1w5luM
youtube/cCnrX1w5luM
youtu.be/cCnrX1w5luM
我尝试了不同的正则表达式，但没有找到适合共享链接的正则表达式。谁能帮我解决这个问题。
这是我用来匹配和捕获 YouTube URL 与视频代码的重要部分的正则表达式：
^((?:https?:)?\/\/)?((?:www|m)\.)?((?:youtube(-nocookie)?\.com|youtu.be))(\/(?:[\w\-]+\?v=|embed\/|live\/|v\/)?)([\w\-]+)(\S+)?$
