Good afternoon,
I have a question in an exercise that I have to solve and I wanted to ask you to help me:
How do I make a function in JavaScript that takes a string as an argument and verifies that an email is valid, that is, if it contains @ is an email. And the function returns a boolean. Thank you
You can validate using this function:
function IsEmail(email){
var exclude=/[^@-.w]|^[[email protected]]|[._-]{2}|[@.]{2}|(@)[^@]*1/;
var check=/@[w-]+./;
var checkend=/.[a-zA-Z]{2,3}$/;
if(((email.search(exclude) != -1)||(email.search(check)) == -1)||(email.search(checkend) == -1)){return false;}
else {return true;}
}
