I need to replace everything between : and , with a | multiple times.
I have a server list like server1:127.0.0.1,server2:127.0.0.2,server3:127.0.0.3.
Basically, I need to remove all the IPs and replace them with some |.
So far I was able to do this:
resultList = serverList.replace(/:.*,/g, '|')
The problem is that the result list is server1|server3:127.0.0.3.
How can I replace every occurrence?
/:.*,/ is greedily matching :127.0.0.1,server2:127.0.0.2. Remember that quantifiers like * will match as much as they can while still allowing the rest of the pattern to match.
Consider specifying [^,] instead of .. This will exclude commas from matching and therefore limit the match to just the region you want to remove.
resultList = serverList.replace(/:[^,]*,/g, '|')
You could take a lazy approach with ? (Matches as few characters as possible).
var string = 'server1:127.0.0.1,server2:127.0.0.2,server3:127.0.0.3';
console.log(string.replace(/:.*?(,|$)/g, '|'));
[^,]*instead of.*
