How to check if my string contains a hyphen, and if it does, how to fetch the string before that hyphen?

Question

The string should contain only one hyphen, eg.if the string is ABC-123, then I need to fetch ABC

Answer 1

You may match on the following pattern:

^[^-]+

This will match the first part of a hyphenated input. It also will match the entire input should the input not have any hyphen at all.

Here is a regex demo .
