Topic: Re: Javascript test for backspace key in Acroform
Conf: (P-PDF) Developers, Msg: 57588

Jennifer,

one approach might be comparing the length of the event.value with
the field.value. This might work because the backspace key does
delete one character, therefore, the event.value would be shorter
than the field.value.

However, I haven't tried it out; it might not work at all.

On the other hand, it might be intersting to hear the results of your
experiments.

Hope, this can help.
