^([+a-zA-Zd._-]+)@([a-zA-Zd]+).([a-zA-z]{2,8})(.[a-zA-z]{2,8})?$
Regex version with capital letters (since everyone converts to lowercase but caps are allowed) and plus(+) before @ and also underscore(_) is allowed before @
Not that this is a Dart/Flutter course, but there's a package in the pub called email_validator which precisely follows the specifications. There's a similar package for Perl called Mail::RFC822::Address that does the right thing again according to the standards. That module creates a regex up from smaller pieces, and for grins got expanded as https://www.ex-parrot.com/pdw/Mail-RFC822-Address.html . Yes, that page of text is the SMALLEST VALID REGEX for a legal email. If your handmade regex is any shorter than that, you will get false negatives. Specifically, the regex here fails on one of my addresses: fred&[email protected], and on one of my friend's addresses: *@qz.to. Yes, a solitary asterisk is a valid email localpart.
Thanks a ton! You are a savior <3 Love from India.
Thanks, for your playlist. But this RegEx wouldn't recognise my student e-mail: [email protected] . But this seams to be a speziell think because by some websites this e-mail causes problems.
no doubt, a great tutorial
When you search for this on c# and this shows up, cmon youtube -__-
Before first lecture : WTF! is this – /^([a-zd.-]+)@([a-zd-]+).([a-z]{2,8})(.[a-z]{2,8})?$/
After last lecture : Oh! this is so easy to understand.
Thanks Net Ninja for this wonderful playlist on Regular Expressions .
Best explanation!!
Your RegEx does not validate emails from subdomains e.g. [email protected] or [email protected]
thankyou you are a great teacher
You forgot to make it case insensitive. Even though emails are already case insensitite (meaning any email in all caps goes to the same address as its lowercase counterpart), capital letters shouldn't make the email address invalid.
5 dislikes from users who are debating the best RegEx for emails.
validator.isEmail()
thanks man
[email protected] this comes as valid email using above expression
🙁
Best explanation ever. You have a talent, keep going. Thank you.
Thank you! Explained it in a easy way…
what about confirm password ? How to validate that ?
Don't know if it is worth noting, but within a character set, the dot('.') doesn't need to be escaped
Thank you very much Bro! you made everything easy love it
How can i fix this error? "Uncaught TypeError: Cannot read property 'test' of undefined"
God bless all the Ninjas in the world !
specially The Net Ninja !!
jani pyara hya tu … love you jani g
This was a HUGE help, thank you
This is great. How would you put it together, by not allowing the "submit" button not to work until all edits have been passed?
Thank you very much friend!!
Great Tutorials🔥🔥 Keep up the good work 💯💯
Thank you so much. I Got headache when I saw RegExp tokens at first time but these videos helped me to understand how these token works
what is the use of ^ (this symbol) ?
why every pattern starts with ^ ?
Such a great and informative video which demystified what is regex and how to use it correctly and nicely. Bravo!
You make complex things turn into easy
Plus (+) is also valid character before the @ symbol. I frequently use plus symbol when I'm sharing my email with the websites. It helps me to track down the spammers.
That feature is natively supported by Gmail and many of the email provider.
^[a-zd-]+@[a-zd-]+(.[a-z]{2,8}){1,2}$
Very useful. Email addresses are very difficult to validate though, and the truth is it doesn’t matter how thorough you make it there’s no guarantee the user will type it in correctly anyway. Usually a confirm email box is added. I would let most characters through apart from those that have potential for malicious input and just check for an @ and dot character. But no way is the perfect way.
I'm procrastinating to learn hard topics until you make the tuts
For many days I was thinking to learning Regular expression, here I found best one
thanks for the awesome course. One thing that would help you make video faster and better would be live-server. https://www.npmjs.com/package/live-server. Will refresh the page for you when there is a change in the project. 🙂
amazing..really necessary
Hello, Thank you once again for the awesome tutorials, just want to point out, emails can also have underscores ( _ ) similar to dashes ( – ), I guess all one needs to do to add it is to add an '_' symbol within the group, right. Thanks.
