match particular url parameter and return its value

Question

I have URL like
https://some-domain/auth/authenticate?auth=1c4cf948-0867-488d-8596&client_id=account&tab_id=0p-SoVza1Sw
I want to get the value of tab_id by using regex.
I have done it through JS but I want a regEx to return 0p-SoVza1Sw.
I tried this /tab_id=([^&]+)&*/g but it matches with tab word also

I know it would be easy but am not good at regex, Thank you

Your value is in capture group 1. You can omit the `&*` if it is optional `tab_id=([^&]+)` — The fourth bird, Jun 17 '20 at 10:19

You could use a lookbehind assertion here:

(?<=[?&]tab_id=)[^&]+
