Answer 1

It is common to check the format of the email is valid or not. To validate email address we need to use regular expression. In MVC razor we should use @@ symbol to perform validation. MVC razor:

var emailRegEx = /^(([^<>()[]\.,;:\s@@\"]+(.[^<>()[]\.,;:\s@@\"]+)*)|(\".+\"))@@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}])|(([a-zA-Z-0-9]+.)+[a-zA-Z]{2,}))$/;

Normal Html:

For normal we should use @ symbol to perform validation

var emailRegEx = /^(([^<>()[]\.,;:\s@\"]+(.[^<>()[]\.,;:\s@\"]+)*)|(\".+\"))@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}])|(([a-zA-Z-0-9]+.)+[a-zA-Z]{2,}))$/;
