Is it possible to have only the acceptable range of user entered data into a numeric field be displayed?

Currently it has a validation script to check if the value is between a certain range but I would like to only allow the acceptable range fill the field. Anything outside the the acceptable range, the field will remain empty.

By using the change event you can moniter and modify data entry as it happens. There are several event properties that hold information about the interactive data entry,

xfa.event.change, xfa.event.prevText, xfa.event.newText, xfa.event.selEnd, and xfa.event.selStart

For example, enter this code into the change event for the entry field. It refuses to enter a value greater than 42.
if(Number(xfa.event.newText) > 42){xfa.event.change = "";xfa.event.selEnd=0 ;xfa.event.selStart=0 ;}
