Re: Email validation into TextField

you can compare the old text and the new text using a regular expression. if the result is false, replace the new with the old text.
I do that in Qt, but it should also be available in QML, see

Try this may be it will help you..

 

function validEmail(emailId) {
var reg = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
if (emailId.length > 0 && reg.test(emailId)) {
return true;
}
return false;
}

Re: Email validation into TextField

Validating emails is actually super complex, and most regular expressions are too restrictive. For example, having example+somestuff@somedomain.com is a vaild address that is often rejected.

Honestly, something simple like just making sure it has an @ symbol in it is probably enough. How valid do you really need it to be? At the end of the day, only way you can really be sure it's correct is to send an email to that address.
