Extjs Form Validtion

Question

I am using Extjs Ext.form.FormPanel to create a form that will contain some fields like name, company,...,etc. Among the fields will be zip code and phone number, let's take the zip code problem, the zip code could be 5 numbers or 5 numbers plus 4 characters, I don't want to create two separate fields for the zip code, is there a way that I could create one field and prevent users from entering the zip code wrongly, just as the following jQuery plugin does:

ExtJS has vtypes, that let you write validation code.

Simpler: TextFields have a regex configuration option that forces match on validation. Your regex can be (assuming space separator then a-z only, case-insensitive):

/^\d{5}(? [a-z]{4})?$/i
