Hello everyone,
I have a PDF form which users need to enter a IP address. In order to get a correct IP address, I need to limit a TextField's pattern.
What my boss want me to realize is like the picture below:
It means when users fill 3 numbers of IP address, it will jump to next place and display a point "." automatically.
But I found it can't change the rawvalue of the TextField when it is in a typing status(in Change event).
Do you think if I can realize this requirement? How can I do ?
Thanks a lot!
Elly

Hi,
you can use a regular expression to verify the entered text.
This script in the fields exit event, will check the entered text against a regular expression.
if (! this.rawValue.match(/\b(?:(?:2(?:[0-4][0-9]|5[0-5])|[0-1]?[0-9]?[0-9])\.){3}(?:(?:2([0-4][0-9]|5[0-5])|[0-1]?[0-9]?[0-9]))\b/ig)) {
xfa.host.messageBox("invalid IP-Address");
}
Here`s a source for regular expression you can try.
