Validate textbox with mask

P: 1
I need to validate a packslip using a mask. In the past I have validated that all characters are numbers and that the first one is not zero. Now they want to be able to set a mask, such as 9XX99999XX where the X is either a letter or integer, 9 would be integer only.

This mask would be different for different suppliers.

Thank you in advance!

the best bet would probably be something around a Regular Expression.

using 9XX99999XX it should be something like
Expand|Select|Wrap|Line Numbers
  1. RE = /\d[a-z0-9]{2}\d{5}[a-z0-9]{2}/i;
  2. // sometimes [:alnum:] can be used for [a-z0-9]
an (more or less technical) explanation to the RegExp object can be found here.
