I am working on request form where target user email address has to be specifically from 'searshc' domain to have him accesses. If user's email address is different than 'email@example.com' he should not be able to raise request as it won't be provisioned.
This works excellent in Google Chrome & Firefox Mozilla but fails for Internet Explorer.
I have checked www.w3schools.com which clearly mentions includes() method only works for IE 12.
I doubt that all our business users have IE version equal or higher than 12 but I am sure that lots of users do use IE than Chrome OR Firefox.
So how can I enable/ disable 'Entitlement Table' field based on email address checking for sub string '@searshc' in it.
