Custom validation script for 8-digit hex number

[Brandt1974]

I can't seem to figure out how to make a custom validation script to validate an 8 digit number in hexadecimal format. I've set the Arbitrary Mask to 'OOOOOOOO' to make sure it's 8 digits long, but the characters must actually be 0-9 or a-f (not case sensitive).

This is what I have but it always says it's invalid:

var regexp = /[^abcdefABCDEF0123456789]*/

if (regexp.test(event.value) == true)

{

    app.alert("Not a valid serial number!");

    event.target.textColor = color.red;

}

else

{

    event.target.textColor = color.black;

}

Please help! Thanks.

Try changing the regular expression to the following:

var regexp = /[^abcdefABCDEF0123456789]+/

With that, all values are considered OK.

oops, actually that worked. Thanks.
