I am not good in Regex and now I am in need of one Regex which accepts only positive whole numbers (like 1,2,3 ... n).

Invalid values are

01, 001, 0, 1.0, -1,-1.0,-01.

Tried this, but its accepting "01" which is not valid in my case.

/[1-9][0-9]*/

Any help will be much appreciated.

Its not duplicate. tried those things. Its accepting "01". I told already, "01" is not valid in my case. – Deepak Apr 15 '20 at 10:24
try this: `^(?![\-0].*$)[\d]+` – Melkor Apr 15 '20 at 10:54

but you are wrong, the linked answer will work as well and is much simpler than mine – Melkor Apr 15 '20 at 11:02
basically your expression is only missing a `^` at the beginning. This indicates that the number must start with 1-9 – Melkor Apr 15 '20 at 11:09
