How To Validate Email Address In JavaScript?

I have been following this guide

But is there any other way i can validate email without using regular expression?

I mean that's what the pattern attribute ... is for.

Html forms have a email property, but beyond that you need a regex on the server for verification

thanks a lot guys

Welcome to devRant. For future reference, this isn't a Q&A forum. Complain at shit and you'll do just fine

The only real way of validating them any longer, apart from the presence of an @ with a string before and a string with one or more dots after, is to send it a mail and see if it works...

You can basically do what the regex does manually.
Splice the parts into fragments and validate them each individually.

But I wouldn’t recommend it, since it can quickly go wrong, plus you HAVE to read the email spec like by line, otherwise it’s gonna be a shitty validator.

Also, keep in mind there are email alias like the google “+” suffix. You probably want to ban them, or validate against your db, too.

Where do you need an email address to begin with?

First rule: you don't validate emails more than "it has one @ in it"

@iiii and one .

@hack no. Not all domains actually have subdomains. All you need is some symbols before @ and some symbols after.

@iiii All domains (and IP addresses) have at least one dot in them, even without having subdomains ;)

Do minimum with input type email and maybe regex that it contains @. That is enough. On backend send confirm your email address email to that address. If you don't want certain email addresses there are black list available.

@Flygger yeah, localhost is a domain without a dot 🙃

@iiii more like an alias, also neither valid in emails or relevant to the subject ;)

@Flygger anyway, by definition, domain specifier does not have to have a dot in it.

@Flygger Thanks a lot.

I found the answers here in this guy blog - https://tutorialscamp.com/how-to-va...

@N00bPancakes Thanks a lot

You could also take a look at these arguments, and in general just the whole list of falsehoods ;)
