Is there a Java implementation of the HTML5 input email validation?

问题 I'd like to use the new <input type="email" /> element. I'd like to have Java code that implements the same validation on the server that happens in the browser. The HTML5 spec defines email addresses in ABNF as: 1*( atext / "." ) "@" ldh-str *( "." ldh-str ) where: <ldh-str> ::= <let-dig-hyp> | <let-dig-hyp> <ldh-str> <let-dig-hyp> ::= <let-dig> | "-" <let-dig> ::= <letter> | <digit> <letter> ::= any one of the 52 alphabetic characters A through Z in upper case and a through z in lower case

PHP FILTER_VALIDATE_EMAIL does not work correctly

由 让人想犯罪 __ 提交于 2019-12-28 05:30:07
问题 I'm using PHP 5.3.10. This is the code: <?php $email = "test@example.c"; if (filter_var($email, FILTER_VALIDATE_EMAIL)) echo "Email: ".$email." correct"; else echo "email not correct"; ?> It returns: "Email: test@example.c correct. I think that a top level domain with only one character is not correct (I'm not aware of one-character-length TLD according to this list: http://data.iana.org/TLD/tlds-alpha-by-domain.txt ). So, FILTER_VALIDATE_EMAIL filter is working correctly or not? 回答1:

Php/javascript email form and validation

由 心不动则不痛 提交于 2019-12-25 06:53:45
问题 So I have the JavaScript code which validates the first name field, I am adding more validation once I have worked this out. So basically if the field is not filled in, return false. If it is return true and continue to email.php to send the email. Only problem is its not sending the email to the set address. I am confused as to where I have gone wrong. The JavaScript is working when the field is empty, and when it has an input. Help. PS: I have removed email address for privacy purposes.

问题 In React, I'm looking to add email validation (checks for @ and .com) to a form that currently checks for empty input fields. I found this that does the job but can't figure out how to connect it to onSubmit along w/ my other validation. Here's the link to this project's codepen for complete code.

Angular conditional email validation

由 二次信任 提交于 2019-12-25 02:35:31
问题 How can I conditionally use angular's email validation based on the presence of another scope variable? I looked through the documentation but the only way I can find to trigger email validation is to use input type="email" , which in this case I cannot use due to the dependence of another directive on type="text" . Ideally I'd either like to assign ng-match="email" based on the value of another scope variable, or just validate the email programatically on submission. In theory I could just a

Send user verification email from dart server

问题 I'm using Aqueduct to build a backend Dart server (but the answer doesn't have to use Aqueduct). When a new user signs up with an email address, I want to send a verification email to them. It will include a link back to the server, or possibly a verification code. My problem is I don't know how to send an email in Dart. I didn't see any package on Pub that looked like it would do it either. Can I do it manually using dart:io or anything? 来源： https://stackoverflow.com/questions/56194778/send
