Hello!

I am using this email validation expression: /^(\w[-._+\w]*\w@\w[-._\w]*\w\.\w{2,3})$/

Although, I had one of the participants inserting an email with spaces in the middle, which wasn't blocked by the validation expression. How can I update the above expression to avoid spaces in the middle of the email address?

Thank you.

Let me Google that for you. Found it:

In other words: there is no 100% valid regex for this.

Which of them should I use in the validation field of LimeSurvey? Which do you suggest?

I have no recommendation, I never use this. If you need it, I would try.

Tammo

w{2,3} : totally false (you have .social, .info etc …)

Else : to have a browser only way : gitlab.com/SondagesPro/QuestionTheme/EmailInput
(you can do same with js workaround).

Sorry, I did not get it. Which would you use? This one?

/^(\w[-._+\w]*\w@\w[-._\w]*\w\.\w{2,3,4})$/

Why not
regexMatch('/^(([^<>()\[\]\\.,;:\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,}))$/',this.NAOK)

in manual.limesurvey.org/Question_type_-_Sh...8em_validation_sq.29

But start by remove the last part on {2,3,4} …

It is not working as expected. I inserted the code here:




Am I missing something?
