如何从网址获取YouTube视频ID？

Question

我想v=id从JavaScript 获取YouTube的URL(没有jQuery,纯JavaScript).

YouTube网址格式示例

http://www.youtube.com/watch?v=u8nQa1cJyX8&a=GxdCwVVULXctT2lYDEPllDR0LRTutYfW

http://www.youtube.com/watch?v=u8nQa1cJyX8

或者在网址中包含视频ID的任何其他YouTube格式.

这些格式的结果

Answer 1

我对"jeffreypriebe"提供的正则表达式进行了增强,因为他需要一种YouTube网址,即视频通过频道时的网址.

好吧不,但这是我武装的功能.

<script type="text/javascript">
function youtube_parser(url){
    var regExp = /^.*((youtu.be\/)|(v\/)|(\/u\/\w\/)|(embed\/)|(watch\?))\??v?=?([^#\&\?]*).*/;
    var match = url.match(regExp);
    return (match&&match[7].length==11)? match[7] : false;
}
</script>

这些是支持的URL类型

可在[http://web.archive.org/web/20160926134334/] http://lasnv.net/foro/839/Javascript_parsear_URL_de_YouTube中找到

Answer 2

我简化了Lasnv的答案.

它还修复了WebDeb描述的错误.

这里是:

var regExp = /^.*(youtu\.be\/|v\/|u\/\w\/|embed\/|watch\?v=|\&v=)([^#\&\?]*).*/;
var match = url.match(regExp);
if (match && match[2].length == 11) {
  return match[2];
} else {
  //error
}

Answer 3

您不需要使用正则表达式.

var video_id = window.location.search.split('v=')[1];
var ampersandPosition = video_id.indexOf('&');
if(ampersandPosition != -1) {
  video_id = video_id.substring(0, ampersandPosition);
}

Answer 4

截至2015年1月1日,这些都没有在厨房水槽上工作,特别是没有protocal http/s和youtube-nocookie域的URL.所以这是一个适用于所有这些不同Youtube版本的修改版本:

// Just the regex. Output is in [1].
/^.*(?:(?:youtu\.be\/|v\/|vi\/|u\/\w\/|embed\/)|(?:(?:watch)?\?v(?:i)?=|\&v(?:i)?=))([^#\&\?]*).*/

// For testing.
var urls = [
    '//www.youtube-nocookie.com/embed/up_lNV-yoK4?rel=0',
    'http://www.youtube.com/user/Scobleizer#p/u/1/1p3vcRhsYGo',

var i, r, rx = /^.*(?:(?:youtu\.be\/|v\/|vi\/|u\/\w\/|embed\/)|(?:(?:watch)?\?v(?:i)?=|\&v(?:i)?=))([^#\&\?]*).*/;

for (i = 0; i < urls.length; ++i) {
    r = urls[i].match(rx);

Answer 6

我创建了一个函数来测试Youtube,Soundcloud或Vimeo嵌入ID的用户输入,以便能够使用嵌入式媒体创建更连续的设计.此函数检测并返回具有两个属性的对象:"type"和"id".类型可以是"youtube","vimeo"或"soundcloud","id"属性是唯一的媒体ID.

在网站上我使用textarea转储,用户可以粘贴任何类型的链接或嵌入代码,包括vimeo和youtube的iFrame嵌入.

function testUrlForMedia(pastedData) {
var success = false;
var media   = {};
if (pastedData.match('http://(www.)?youtube|youtu\.be')) {
    if (pastedData.match('embed')) { youtube_id = pastedData.split(/embed\//)[1].split('"')[0]; }
    else { youtube_id = pastedData.split(/v\/|v=|youtu\.be\//)[1].split(/[?&]/)[0]; }
    media.type  = "youtube";
    media.id    = youtube_id;
    success = true;
}
else if (pastedData.match('http://(player.)?vimeo\.com')) {
    vimeo_id = pastedData.split(/video\/|http:\/\/vimeo\.com\//)[1].split(/[?&]/)[0];
    media.type  = "vimeo";
    media.id    = vimeo_id;
    success = true;
}
else if (pastedData.match('http://player\.soundcloud\.com')) {
    soundcloud_url = unescape(pastedData.split(/value="/)[1].split(/["]/)[0]);
    soundcloud_id = soundcloud_url.split(/tracks\//)[1].split(/[&"]/)[0];
    media.type  = "soundcloud";
    media.id    = soundcloud_id;
    success = true;
}
if (success) { return media; }
else { alert("No valid media id detected"); }
return false;
}

Answer 7

鉴于YouTube有各种各样的URL样式,我认为Regex是一个更好的解决方案.这是我的正则表达式:

^.*(youtu.be\/|v\/|embed\/|watch\?|youtube.com\/user\/[^#]*#([^\/]*?\/)*)\??v?=?([^#\&\?]*).*

第3组拥有您的YouTube ID

YouTube网址示例(目前包括"旧版嵌入网址样式") - 上述正则表达式适用于所有这些网址:

Answer 8

在这里比赛晚了，但是我总结了来自螳螂和jw的两个出色反应。首先，修改后的正则表达式：

const youtube_regex = /^.*(youtu\.be\/|vi?\/|u\/\w\/|embed\/|\?vi?=|\&vi?=)([^#\&\?]*).*/

这是测试代码（我已将mantish的原始测试用例添加到jw的更原始的用例中）：

  var failures = 0;

实验版本，用于处理评论中提到的m.youtube网址：

const youtube_regex = /^.*((m\.)?youtu\.be\/|vi?\/|u\/\w\/|embed\/|\?vi?=|\&vi?=)([^#\&\?]*).*/

需要在测试中的两个位置parsed[2]将其更改parsed[3]（然后通过m.youtube添加到测试中的URL 进行传递）。如果您发现问题，请告诉我。

Answer 9

我有一个支持常用网址的正则表达式，其中还包括YouTube Shorts

正则表达式模式：

(youtu.*be.*)\/(watch\?v=|embed\/|v|shorts|)(.*?((?=[&#?])|$))

JavaScript 返回方法：

function getId(url) {
  let regex = /(youtu.*be.*)\/(watch\?v=|embed\/|v|shorts|)(.*?((?=[&#?])|$))/gm;
  return regex.exec(url)[3];
}

支持的 URL 类型：

Answer 10

此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

Answer 11

TL;博士.

匹配此问题上的所有URL示例,然后匹配一些.

let re = /^(https?:\/\/)?((www\.)?(youtube(-nocookie)?|youtube.googleapis)\.com.*(v\/|v=|vi=|vi\/|e\/|embed\/|user\/.*\/u\/\d+\/)|youtu\.be\/)([_0-9a-z-]+)/i;
let id = "https://www.youtube.com/watch?v=l-gQLqv9f4o".match(re)[7];

ID将始终位于匹配组7中.

我从这个问题的答案中抓取的所有URL的实例:https: //regexr.com/3u0d4

完整说明:

随着许多答案/评论的提出,youtube视频网址有很多格式.即使是多个顶级域名,它们也可以"托管".

您可以按照上面的regexr链接查看我检查过的完整变体列表.

让我们分解RegExp.

^将字符串锁定到字符串的开头. (https?:\/\/)?可选协议http://或https:// ?使前一项可选,因此s然后整个组(括在一组括号中的任何内容)都是可选的.

好的,下一部分就是它的核心.基本上我们有两个选项,各种版本的www.youtube.com/... [id]和链接缩短了youtu.be/[id]版本.

(                                                  // Start a group which will match everything after the protocol and up to just before the video id.
  (www\.)?                                         // Optional www.
  (youtube(-nocookie)?|youtube.googleapis)         // There are three domains where youtube videos can be accessed. This matches them.
  \.com                                            // The .com at the end of the domain. 
  .*                                               // Match anything 
  (v\/|v=|vi=|vi\/|e\/|embed\/|user\/.*\/u\/\d+\/) // These are all the things that can come right before the video id. The | character means OR so the first one in the "list" matches.
  |                                                // There is one more domain where you can get to youtube, it's the link shortening url which is just followed by the video id. This OR separates all the stuff in this group and the link shortening url.
  youtu\.be\/                                      // The link shortening domain
)                                                  // End of group

最后,我们让小组选择视频ID.至少一个字符是数字,字母,下划线或短划线.

([_0-9a-z-]+)

通过指向regexr链接并查看表达式的每个部分如何与url中的文本匹配,您可以找到有关正则表达式每个部分的更多详细信息.

Answer 12

我发现（从2019年开始）的最佳解决方案是：

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。

Answer 13

由于YouTube视频ID设置为11个字符,因此我们可以substring在将网址拆分后立即使用v=.然后我们最终不依赖于&符号.

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

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

好又简单:)

Answer 14

我已经总结了所有的建议，这里是这个问题的通用和简短的答案：

if(url.match('http://(www.)?youtube|youtu\.be')){
    youtube_id=url.split(/v\/|v=|youtu\.be\//)[1].split(/[?&]/)[0];
}
