How do I get the YouTube video ID from a URL?

Question

I want to get the v=id from YouTube’s URL with JavaScript (no jQuery, pure JavaScript).

Example YouTube URL formats

http://www.youtube.c

Answer 1

Late to the game here, but I've mashed up two excellent responses from mantish and j-w. First, the modified regex:

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

Here's the test code (I've added mantish's original test cases to j-w's nastier ones):

 var urls = [
      'http://www.youtube.com/watch?v=0zM3nApSvMg&feature=feedrec_grec_index',
      'http://www.youtube.com/user/IngridMichaelsonVEVO#p/a/u/1/QdK8U-VIH_o',

      'http://youtu.be/dQw4w9WgXcQ?feature=youtube_gdata_player'
  ];

  var failures = 0;
  urls.forEach(url => {
    const parsed = url.match(youtube_regex);
    if (parsed && parsed[2]) {
      console.log(parsed[2]);
    } else {
      failures++;
      console.error(url, parsed);
    }
  });
  if (failures) {
    console.error(failures, 'failed');
  }

Experimental version to handle the m.youtube urls mentioned in comments:

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

It requires parsed[2] to be changed to parsed[3] in two places in the tests (which it then passes with m.youtube urls added to the tests). Let me know if you see problems.

Answer 2

Simple regex if you have the full URL, keep it simple.

results = url.match("v=([a-zA-Z0-9]+)&?")
videoId = results[1] // watch you need.

Answer 3

I simplified Lasnv's answer a bit.

It also fixes the bug that WebDeb describes.

Here it is:

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 4

The best solution (from 2019-2020) I found is that:

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];
}

I found it here.

Answer 5

I made an enhancement to Regex provided by "jeffreypriebe" because he needed a kind of YouTube URL is the URL of the videos when they are looking through a channel.

Well no but this is the function that I have armed.

<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>

These are the types of URLs supported

Answer 6

If someone needs the perfect function in Kotlin to save their time. Just hoping this helps

fun extractYTId(ytUrl: String?): String? {
    var vId: String? = null
    val pattern = Pattern.compile(
        "^https?://.*(?:youtu.be/|v/|u/\\w/|embed/|watch?v=)([^#&?]*).*$",
        Pattern.CASE_INSENSITIVE
    )
    val matcher = pattern.matcher(ytUrl)
    if (matcher.matches()) {
        vId = matcher.group(1)
    }
    return vId
}
