Input Mask #AAA##

[endoflux]

This may be more of an HTML question, but it's for a database function, and I hve a feeling I'll find my answer more quickly here:

I want to limit entry on this code to an entry of #AAA## where # is Numeric and A is Alpha, and either notify the user real-time that the format is wrong, or just have invalid characters not register. What would be the easiest way to accomplish this?

<input type="text" name="RecNum" size=6 maxlength="6">

Thanks!

use regular expressions

-DNG

try this:

^[0-9][A-Z][A-Z][A-Z][0-9][0-9]$

-DNG

ok as i have some free time now...here is the complete function...

Function InputMask(input)
  Dim re
  Set re = new RegExp

  re.IgnoreCase = false
  re.global = false
  re.Pattern = "^[0-9][A-Z][A-Z][A-Z][0-9][0-9]$"

  InputMask = re.Test(input)
End Function

just call the function with the input as the text of your input text box...
