I'm currently working on a project in which I need to fetch street/city details from a DB using a zipcode. Dutch zipcodes use a "1111 AA" format, I would like to have this entered in a single input field while forcing the first four characters to be numeric and the last two to be alphabetical.I've been googling this quite a bit, have found ways to force either one, but none to combine it into a single input field and I don't seem to be crafty enough to combine them myself.Thank you.
Force different characters at different positions
