How to get the domain in a variable?

Question

I'm running multiple codes with different domains. I do not want to put the domain manually. For example: var domainName = 'domain.com.br';

I would like to know if it is possible to get the domain (G Suite) through a variable. For example: var domainName = get.domain ();

Answer 1

Use Session.getActiveUser().getEmail() / Session.getEffectiveUser().getEmail() to get the active/effective user email address and JavaScript string handling techniques like using regular expressions:

 var domain = Session.getActiveUser().getEmail().match('\@(.*)$')[1]

Validation of regex expression

var match = 'useraname@example.com'.match('\@(.*)$');
console.info(match[1])
