I am trying to extract video id using regex. Here are some video url examples:
http://fast.wistia.net/embed/iframe/26sk4lmiix
https://support.wistia.com/medias/26sk4lmiix
My regex:
var rx = /https?://(.+)?(wistia.com|wi.st)/(medias|embed)/*/([^;?]+)/,
_m = url.match(rx)
if(_m && _m[4])return _m[4]
else return false;
Regiex is not quite correct and is returning for exmaple:
iframe/26sk4lmiix

If you just want to extract the last portion of the URL path component via regex, then just match on the patttern [^/]+$:
var url = "http://fast.wistia.net/embed/iframe/26sk4lmiix";
var id = url.match(/[^/]+$/);
console.log(id);You could also split the URL on forward slash, and retain the final component:
var url = "http://fast.wistia.net/embed/iframe/26sk4lmiix";
var parts = url.split("/");
console.log(parts[parts.length-1]);3
Here is the code without using the regex pattern.
function getVideoId(url) {
return url.split("/").pop();
}
const url1 = "http://fast.wistia.net/embed/iframe/26sk4lmiix";
console.log(getVideoId(url1));
const url2 = "https://support.wistia.com/medias/26sk4lmiix";
console.log(getVideoId(url2));
Output of url1: 26sk4lmiix
Output of url2: 26sk4lmiix
If you want to keep your current group patterns intact, you may use
/https?://([^/]+)?(wistia.(?:com|net)|wi.st)/(medias|embed)(?:/.*)?/([^;?]+)/
The (.+)? is changed to ([^/]+)? to make sure the first group value is only matching within the hostname part.
I changed (wistia.com|wi.st) to (wistia.(?:com|net)|wi.st) since you have such an example with wistia.net to match.
The (?:/.*)? part makes sure you match anything before an expected value that is captured into Group 4.
