sez "Chipp Walters" <[EMAIL PROTECTED]>:
Thanks Richard,
While your script works fine for numbers, it can't easily validate
email addresses, social-security numbers, zip codes, etc.. I really
need a single place I can put all this validation stuff, as the
project I'm working on has over 50 different input screens.
Looking at Richard's original script, it seems to me that there's at
least one semi-obvious way to go...
on keyDown k
put false into LetItPass
put the length of the target into TargLen
switch (the uValidationType of the target)
case "integer"
if k is in "0123456789" then put true into LetItPass
break
case "zipcode"
# 5-digit ZIPs: 5 digits
# 9-digit ZIPs: 5 digits, 1 dash, 4 digits
if TargLen = 6 then
# the user is typing the *6th* char, which must be a dash
if k is "-" then put true into LetItPass
else if TargLen < 11 then
# the user is typing any other char, which much be a digit
if k is in "0123456789" then put true into LetItPass
end if
break
case "socialsecurity"
# 3 digits one dash, 2 digits, 1 dash, 4 digits; total of 11 chars
if ((TargLen = 3) or (TargLen = 6)) then
# the user is typing either the 4th or 7th char;
# either way, it's gotta be a dash
if k is "-" then put true into LetItPass
else if TargLen < 12 then
# any other char in the string, it's a digit
if k is in "0123456789" then put true into LetItPass
end if
break
case "complicated"
# this particular class of input needs a highly complex
validation scheme
if ThisComplexValidator (k, (the target)) then put true into
LetItPass
break
default
put true into LetItPass
# if you want to be fussy about input validation,
# *don't* put true into LetItPass by default; rather,
# leave LetItPass alone
end switch
if LetItPass then pass keyDown
end keyDown
Hope this helps...
