我如何从一个URL获得YouTube视频ID ?

截至2015年1月1日，这些都不能在厨房里工作，特别是没有http/s协议和youtube-nocookie域的url。这里有一个修改过的版本，适用于所有这些不同的Youtube版本:

// Just the regex. Output is in [1]. /^.*(?:(?:youtu\.be\/|v\/|vi\/|u\/\w\/|embed\/|shorts\/)|(?:(?:watch)?\?v(?:i)?=|\&v(?:i)?=))([^#\&\?]*).*/ // For testing. var urls = [ 'https://youtube.com/shorts/dQw4w9WgXcQ?feature=share', '//www.youtube-nocookie.com/embed/up_lNV-yoK4?rel=0', 'http://www.youtube.com/user/Scobleizer#p/u/1/1p3vcRhsYGo', 'http://www.youtube.com/watch?v=cKZDdG9FTKY&feature=channel', 'http://www.youtube.com/watch?v=yZ-K7nCVnBI&playnext_from=TL&videos=osPknwzXEas&feature=sub', 'http://www.youtube.com/ytscreeningroom?v=NRHVzbJVx8I', 'http://www.youtube.com/user/SilkRoadTheatre#p/a/u/2/6dwqZw0j_jY', 'http://youtu.be/6dwqZw0j_jY', 'http://www.youtube.com/watch?v=6dwqZw0j_jY&feature=youtu.be', 'http://youtu.be/afa-5HQHiAs', 'http://www.youtube.com/user/Scobleizer#p/u/1/1p3vcRhsYGo?rel=0', 'http://www.youtube.com/watch?v=cKZDdG9FTKY&feature=channel', 'http://www.youtube.com/watch?v=yZ-K7nCVnBI&playnext_from=TL&videos=osPknwzXEas&feature=sub', 'http://www.youtube.com/ytscreeningroom?v=NRHVzbJVx8I', 'http://www.youtube.com/embed/nas1rJpm7wY?rel=0', 'http://www.youtube.com/watch?v=peFZbP64dsU', 'http://youtube.com/v/dQw4w9WgXcQ?feature=youtube_gdata_player', 'http://youtube.com/vi/dQw4w9WgXcQ?feature=youtube_gdata_player', 'http://youtube.com/?v=dQw4w9WgXcQ&feature=youtube_gdata_player', 'http://www.youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player', 'http://youtube.com/?vi=dQw4w9WgXcQ&feature=youtube_gdata_player', 'http://youtube.com/watch?v=dQw4w9WgXcQ&feature=youtube_gdata_player', 'http://youtube.com/watch?vi=dQw4w9WgXcQ&feature=youtube_gdata_player', 'http://youtu.be/dQw4w9WgXcQ?feature=youtube_gdata_player' ]; var i, r, rx = /^.*(?:(?:youtu\.be\/|v\/|vi\/|u\/\w\/|embed\/|shorts\/)|(?:(?:watch)?\?v(?:i)?=|\&v(?:i)?=))([^#\&\?]*).*/; for (i = 0; i < urls.length; ++i) { r = urls[i].match(rx); console.log(r[1]); }

由于YouTube视频id被设置为11个字符，我们可以简单地在用v=分割url后使用子字符串。那么我们就不依赖于最后的&号了。

var sampleUrl = "http://www.youtube.com/watch?v=JcjoGn6FLwI&asdasd";

var video_id = sampleUrl.split("v=")[1].substring(0, 11)

很好很简单:)

function parser(url){
    var regExp = /^.*((youtu.be\/)|(v\/)|(\/u\/\w\/)|(embed\/)|(watch\/)|(\?v=|\&v=))([^#\&\?]*).*/;
    var match = url.match(regExp);
    if (match && match[8].length==11){
            alert('OK');
    }else{
            alert('BAD');
    }
}

试试这个——

function getYouTubeIdFromURL($url) 
{
  $pattern = '/(?:youtube.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu.be/)([^"&?/ ]{11})/i';
  preg_match($pattern, $url, $matches);

  return isset($matches[1]) ? $matches[1] : false;
}

我们认识这些人物?”v="永远不会出现多于一个，但'v'可以以某种方式出现在本我本身，所以我们使用"?V ="作为分隔符。看到它在这里工作

//Get YouTube video Id From Its Url

     $('button').bind('click',function(){
var 
url='http://www.youtube.com/watch?v=u8nQa1cJyX8',
videoId = url.split('?v='),//Split data to two
YouTubeVideoId=videoId[1];
alert(YouTubeVideoId);return false;

});

<button>Click ToGet VideoId</button>
