Question

Currently I have implemented a Javascript Ajax search where if user types a city name I am populating the name in the search result. Problem is there are cities which have alternate names (for example Mumbai has Bombay as alternate name…..Bangalore has Bengaluru as alternate name). I want to map the alternate names of the city to the correct name using javascript. ALSO there might be multiple alternate names for the city not only one. so how can I map alternate cities name to correct one using javascript.

Answer 1

var alternates = {
    Bombay    : "Mumbai",
    Bengaluru : "Bangalore",
}

var userCity = obtainUserInputSomehow()
if (alternates.hasOwnProperty(userCity)) { userCity = alternates[userCity] }
// after this userCity will have "Mumbai" if user entered "Bombay" or "Mumbai".
// add as many aliases as you need.
