email-validation

I am new in learning Angular2, and I want to make a validation form that verifies emails after a RegEx pattern. My code looks something like this but I don't have any idea if I am doing it right, or what I did wrong, can somebody please help me a bit? Thank you! I fixed it. Thank you a lot everybody. <div class="alert-email"> <label for="contactemail">EMAIL: </label> <input type="email" id="contactemail" name="contactemail" required ng-pattern="/^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/" [(ngModel)]="model.contactemail" #contactemail="ngModel" placeholder="Your

I'm working on this alerting service in Rails. And really, all I need to do is, when a user signs up, send a confirmation email to the user. And upon confirmation from the user, activate the user. I tried playing around with Matt Hooks' Authlogic email activation tutorial, but its really leading nowhere. So , any ideas how I can do this with minimum fuss ? Thanks ! UPDATE So how i got devise to do the job for me is : Install the gem. Create a migration for devise's confirmable fields. Specify devise :confirmable in your model. Create a confirm method in the relevant controller(and a route for

Normally validation of simple email is: /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/ This will validate email like test@test.com But how to validate if email is multiple? entry 1: test@test.com, test1@test.com, test2@test.com entry 2: test@test.com , test1@test.com , test2@test.com entry 3: test@test.com, test1@test.com , test2@test.com entry 4: test@test.com This emails is a possible entries that user will input. Also expect thier is 2 or 3 or 4 or more emails sometimes. Thanks for the answers. Split the emails on a comma and validate the entries var x = getEmails(); var

What's a good technique for validating an e-mail address (e.g. from a user input field) in Android? org.apache.commons.validator.routines.EmailValidator doesn't seem to be available. Are there any other libraries doing this which are included in Android already or would I have to use RegExp? Don't use a reg-ex. Apparently the following is a reg-ex that correctly validates most e-mails addresses that conform to RFC 2822 , (and will still fail on things like "user@gmail.com.nospam", as will org.apache.commons.validator.routines.EmailValidator) (?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/

Here's a regex for validating emails - \S+@\S+\.\S+ , I didn't write it. I'm new to Regular Expressions and do not understand them all that well. I have a couple of questions: What's wrong with the above RegEx? What's a good RegEx for validating emails? Paolo Bergantino "How do I validate an email with regex" is one of the more popular questions that come up when it comes to regular expressions and the only real good answer is "you don't". It has been discussed in this very website in many occasions . What you have to understand is that if you really wanted to follow the spec, your regex would

I need to know how check if email address is valid without using link in email confirmation. How can I do this? TFD You can't, end of story. Even using email confirmation only proves that the email address was valid at that time. It could then be shut down a second later! Same for any other Internet based ID systems like OpenID, they can be set up and shut down just for the duration of the registration process. Even credit card ID can be one off since the invention of the disposable "debit" credit card. Only government ID systems are likely to be valid for any length of time. There are major

I'm trying to make a Bash script to check if an email address is correct. I have this regular expression: [a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])? Source: http://www.regular-expressions.info/email.html And this is my bash script: regex=[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])? i="test@terra.es" if [[ $i=~$regex ]] ; then echo "OK" else echo "not OK" fi The script fails and give me this output: 10: Syntax error:
