我正在尝试从youtube链接中检索播放列表ID,如:
https://www.youtube.com/watch?v=hv_X327YUdI&list=SPGznEl712WelO6ZhS8lc2ssweLuQaCKld
或
https://www.youtube.com/playlist?list=SPGznEl712WelO6ZhS8lc2ssweLuQaCKld
拒绝不属于youtube的链接。
所以在这种情况下,结果将是:
SPGznEl712WelO6ZhS8lc2ssweLuQaCKld
答案 0 :(得分:3)
这就是我最终做到的方式:
此函数验证链接来自youtube:
function youtube_validate(url) {
var regExp = /^(?:https?:\/\/)?(?:www\.)?youtube\.com(?:\S+)?$/;
return url.match(regExp)&&url.match(regExp).length>0;
}
此功能检索播放列表ID
//get playlist id from url
function youtube_playlist_parser(url){
var reg = new RegExp("[&?]list=([a-z0-9_]+)","i");
var match = reg.exec(url);
if (match&&match[1].length>0&&youtube_validate(url)){
return match[1];
}else{
return "nope";
}
}

好的,我想你已经提取了链接:
var link = 'https://www.youtube.com/watch?v=hv_X327YUdI&list=SPGznEl712WelO6ZhS8lc2ssweLuQaCKld';
var reg = new RegExp("[&?]list=([a-z0-9_]+)","i");
var match = reg.exec(link);
alert(match[1]);
解释
[&?] one of these characters
list=
( capture group 1
[A-Za-z0-9_]+ all characters that are in [A-Za-z0-9_], one or more times
) close capture group 1

从网址获取播放列表ID
function playlist_id(url) {
var VID_REGEX = /^.*(youtu.be\/|v\/|u\/\w\/|embed\/|watch\?v=|\&v=)([^#\&\?]*).*/
var regPlaylist = /[?&]list=([^#\&\?]+)/;
var match = url.match(regPlaylist);
return match[1];
}
从播放列表网址获取视频ID
function video_id_from_playlist(url) {
var VID_REGEX = /^.*(youtu.be\/|v\/|u\/\w\/|embed\/|watch\?v=|\&v=)([^#\&\?]*).*/
var video_id = url.match(VID_REGEX)[2];
return video_id ;
}
或网址中的视频ID
function get_video_id(url) {
url = url.split(/(vi\/|v=|\/v\/|youtu\.be\/|\/embed\/)/);
return (url[2] !== undefined) ? url[2].split(/[^0-9a-z_\-]/i)[0] : url[0];
}
