    Set a minimum amount of numbers for Text Boxes

    Asked by Celltechadvisors on January 24, 2014 at 02:43 PM


    I had a question about setting a minimum amount of numbers for a text box on my form. I have a text box that requires 15 digits however i have noticed people are entering one or two digits less but they can still submit the form. As of now, I have not figured out how to activate this feature with JotForm, is there anyway I can do this?

    Thank you for contacting us.

    There is no native minLength attribute in HTML, so that we do not have such option. However, we might add some custom solution in the future.

    In the meantime, you can try an Input Mask option:

    This way, users will see filled part on the input.

    If you need any further assistance, please let us know.
