Validating Comma Delimited email Addresses Using JavaScript
 Technote (troubleshooting)
 
Problem(Abstract)
This document describes how to validate comma delimited email addresses using JavaScriptâ„¢
 
Resolving the problem
In order to validate email address that are separated by commas and be certain that only one @ symbol was used with each address.
This issue is solved by developing a JavaScript function, which takes the following three parameters:
  • form object

  • field object

  • field name.

The field object is then passed into an array. If it contains commas, it is separated using the split() method.

The next test is to identify whether the email matches the pattern /(\S+)(@)(\S+)/ where (/S+) represents non-whitespace characters. If the address fails an alert is thrown.

The pattern described above will pass because the (/S+) matches all non-whitespace characters. The next step is to test for an additional @ symbol. If one is found, an alert is thrown.
