Validation - Alphanumeric but can't start with a number?Asked by rebirthdesign on February 27, 2014 at 03:10 AM
I'm wondering what kinds of additional tricks can be applied to the validation that can be applied to text boxes etc? Presently it can be none; alpha; alphanumeric; numeric; or email.
How can I have alphanumeric but NOT say allow user to start their input with a number?
There is actually one other option which is very close to your requirement. You you know / have the format of the input text, you can actually use our "Input Mask" property of "Text Box" field. Please check the screenshot below:
Please check this demo form I created for you: http://www.jotformpro.com/form/40573241260950 In this, I have added an input max for 10 character but the first characted cannot be a number. Please be noted that while setting up input max, you should use @ symbol to mask letters inputs, # for numbers and * for both.
Feel free to clone this form for a closer look. The following guide should help you in form cloning: https://www.jotform.com/help/42-How-to-Clone-an-Existing-Form-from-a-URL
Hope this helps. Do get back to us if you have any questions.
Thanks - this works great on text box field - what about email fields? I don't see the input mask property. Perhaps I'll have to go the js route?
Thanks to please advise!
Input Masking is not enabled into our Email Field. Yes, I think that the only way is to use our source codes and apply a custom validation.
We'll see if we can come up for an example.
