I'm currently working on extracting the second occurrence in a regular expression string.
Let's consider a domain name:
https://regexrocks.com/my/socks/offWe want to replace everything after .com
$this.val($this.val().replace(/(([^.]*.)[^]?.[^\/]?)/, ''));The regex being used is:
(([^.]*.)[^]?.[^/]?)
This will replace the first match with the second: /my/socks/off.
https://regex101.com/r/46BIqG/1
Is there a way to capture the second match instead?
The regex you are using replaces the first match with an empty string while keeping the rest of the original string intact.
Give this a try:
"https://regexrules.com/for/beginners".match(/(.*\.com)(.*)/);
This will give you an array of capture groups, with group 1 at index 1 and group 2 at index 2.
For example, to access group 1:
"https://regexrules.com/for/beginners".match(/(.*\.com)(.*)/)[1]; //https://regexrules.com
And to access group 2:
"https://regexrules.com/for/beginners".match(/(.*\.com)(.*)/)[2]; ///for/beginners
Instead of using replace(), try accessing index 0 of the result from a match():
url.match(/(([^.]*.)[^]?.[^/]?)/)[0]
// This should give you "https://regexrocks.com"
If you're dealing with URLs, you can also utilize an anchor tag <a> for a neat trick:
var url = document.createElement('a');
url.href = 'http://www.example.com/path/to/something';
console.log(url.origin); // Outputs "http://www.example.com"
