Javascript Regex to find any number (greater than 0) between two colons

Question:

Tag: javascript,regex,string

I've tried this: /:(/d+)/:/i

and this: /:/[1-9]*/:/i

But nothing seems to work. So ideally anything from :1: to :9999999999999999999: would be found


Answer:

You can use this regex:

/:(?!0*:)\d+:/

(?!0*:) is a negative lookahead that will fail the match if only 0s are found between colons.
