jQuery regex match returning empty string

Question

I need to strip out the IDs of embedded youtube videos, so I have the url which is something like:

www.youtube.com/embed/[someID]&rel=0&controls=0&showinfo=0&frameborder=1&modestbranding=1

All I want is the [someID] string. I have declared an empty array to store the regex matches;

var videoID = [];

The closest I have come to a solution is:

videoID = videoID.match("embed/(\w*)");

but this results in the following:

video[0] ("embed/")
video[1] ()

jQuery isn't a language. You're writing JavaScript. JS doesn't have any builtin URL parsing capabilities, so you'll have to do some sort of string manipulations: url.split('&')[0].split('/').slice(-1)[0] — Blender

Use this:

url = "www.youtube.com/embed/someID&rel=0&controls=0&showinfo=0&frameborder=1&modestbranding=1";

Then use either:

var videoID = url.match(/embed\/(\w*)/); // regex

OR else:

var videoID = url.match("embed/\\w*)"); // regex object

Both will give this output:

["embed/someID", "someID"]

If you provide a string then String#match method will attempt to construct a RegExp object and for that case you need to use \\w instead of \w.

Try this you may get id. I didn't use regex but still we can get id from above demo like urls.

var url ="www.youtube.com/embed/[someID]&rel=0&controls=0&showinfo=0&frameborder=1&modestbranding=1";

var urlQueries = url.split('/'); 
var queryParameters = urlQueries[2].split('&'); // arrays of all query parameters
var id = queryParameters[0]; // get ids at index 0

I'm not sure if jquery can do Positive-Lookbehinds, but try this (?<=embed\/)([^&]*)

If not, then (?:embed\/)([^&]*) is closer to your example.
