How to create a text only format on text box

[Sami264609519b2o]

I've created a fillable form and i'd like to create a text only textbox.

For instance, it's possible to create a date-specific text box, I'd like to do the same but only for text only and no other characters.

Please advise?

Hi,

You can do that on the validate of the field something like this

// event.rc = return true to let the value stay in the field, false to revert
// event.value.match = test the string against a Regex, returns true or false
// "[A-z]" - regex that allows all capital and lower case letters.
event.rc = event.value.match("[A-z]");

Did you test this code? Because it doesn't work... Instead, use this as the field's custom Keystroke script:

event.rc = /^[a-z]*$/i.test(event.change);

yes and it worked, although I had more than one text field, as the field has to loose focus for the code to run,

This file is empty, and when I used that code myself I was able to enter numbers into the text field. See attached.

HI,

yes, but when you exit it resets to the previous text,  your answer is better.

I can't see any form field in the document?
