Why does HTML5 form-validation allow emails without a dot?
I'm writing a very simple mock-up to demonstrate some HTML5 form-validation. However, I noticed the email validation doesn't check for a dot in the address, nor does it check for characters following said dot.
In other words, "john@doe" is considered valid, when it's clearly not a valid email address; "doe" isn't a domain.
This is how I'm coding my email field:
<input type="email" required />
Is that not enough?
Check this fiddle to see what I mean.
Note: I know how to accomplish this via a RegEx pattern instead. I'm just wondering how someone could get away with using the email type instead.
Answer
You can theoretically have an address without a "." in.
Since technically things such as:
user@com
user@localserver
user@[IPv6:2001:db8::1]
Are all valid emails.
So the standard HTML5 validation allows for all valid E-mails, including the uncommon ones.
