Form autocomplete from a txt file

Hi! I am using this jQuery plugin to autocomplete certain form fields. However, I haven’t understood if it’s possible to use a txt file with it.

If it’s not possible, can you suggest me another plugin? The text file is like this:

cityName;zipCode

Is there a way to autocomplete the city field and the zip code field with the relative values or am I asking too much? :slight_smile:
