JavaScript regular expression for the validation of comma separated string

Issue

I want to validate whether the user enter data in this form B101,202,BBB,B902,Z-102 That is each value can be only of alphabets, digits or alphanumeric + '-' Tried this expression but it failed for alphabets and digits only condition. ^[A-Za-z0-9]+(,[A-Za-z0-9]+)*[A-Za-z0-9]+$

Solution

Please try the following regex

^[A-Z0-9]+((,|-)[A-Z0-9]+)*[A-Z0-9]+$

This checks the following:

• Starts with Alphabets or Numeric
• Ends with Alphabets or Numeric
