I am writing a regular expression(regex) for adding multiple email ids in an input box with following conditions:
AngularJS trims the input by default, so you need to use ng-trim="false" in order to pass leading and trailing whitespace to your pattern regex.
See documentation:
ngTrim (optional)
If set to
falseAngular will not automatically trim the input. This parameter is ignored forinput[type=password]controls, which will never trim the input.(default: true)
