We need to match ZIP codes to neighborhoods/towns for a survey in an urban area. We have a CSV file with ZIP codes and neighborhoods. In some cases a ZIP code intersects with several neighborhoods.
Thus, we need to ask a follow-up multiple choice question that asks respondents which of the matching neighborhoods they actually live in. Basically we need to pull the array of neighborhoods that match the ZIP code the respondent enters; then list them as multiple choice options.
I have some background with PHP and SQL, but am a total JS novice.
Thanks!
