restrict special characters

[Former Community Member]

I would like to restrict a field so that only letters, apostrophes’ and hyphens can only be used. (name fields)

Therefore I would like to restrict all other speial characters such as "\[:;<?!~

I have tried the following script in the change event but it is not working:

xfa.event.change = xfa.event.change.replace(/[\"\\[:;<?!~]/g, "");

Can anyone offer any suggestions?

Thanks,

Nik

Try the below in the change event of the control.. Language needs to set to Java Script..

if (xfa.event.change.match(/[a-z\A-Z\'\-\,]/) == null)
     xfa.event.change = "";

Thanks

A version that also handles pasting (place it in the field's change event):

xfa.event.change = xfa.event.change.match(/[A-Za-z'-]*/)[0];

Note that your form fillers won't be able to enter digits or non-us chars, such as ü, å, ä ö, ñ.
