Why isn't email validation checking for space?

    Email field with validation turned on is correctly identifying the following as invalid:






    However, when I type in an email address with a space in it, the validation didn't catch it and allowed it to be submitted.  For example, "test email@mail.com" is accepted.


    Thank you.

    Hi BPTGuy,

    Well since we knew that emails can't contain any spaces, you can always remove it manually. Or if that's important to you, you can always download your form source code and modify email regex under jotform.js.

    Find this on jotform.js file:

    var reg = {

    and replace the email regex below it to this:

    email: /^\S[a-z0-9!#$%&'*+\/=?\^_`{|}~\-]+(?:\.[a-z0-9!#$%&'*+\/=?\^_`{|}~\-]^\S+)*@(?:[a-z0-9](?:[a-z0-9\-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9\-]*[a-z0-9])/i,

    Example: https://shots.jotform.com/elton/email_nospace/

    Hope this still helps. Thanks!

    Hi EltonCris,

    Thank you very much for your reply.  I certainly know that email addresses cannot contain any spaces, but that's not the point.  The idea of having email address valiation is to prevent people from entering invalid email address.  If the validation can catch the mistake of having double @@ or no @, why can't it also catch the space in the bad email address?

    Thank you for the workaround you provided.
