Input text field w/ autocomplete via array

Greetings!

I’ve parsed a tnsnames.ora file and have a large array of variables (name.world). Regardless of where the data is coming from, though, have any of you happened across a reliable way to listen to input text (onChange) and autocomplete the field against the array of string variables?

Thank you so much for any help. I’m close to getting this done but my autocomplete is more like auto-frustrate the programmer right now.

Curious to see your result Dunlavy!
