Question & Answer :
Reasonably fresh to Google Maps API. I’ve bought an array of information that I privation to rhythm done and game connected a representation. Appears reasonably elemental, however each the multi-marker tutorials I person recovered are rather analyzable.
Fto’s usage the information array from Google’s tract for an illustration:
var places = [ ['Bondi Formation', -33.890542, 151.274856, four], ['Coogee Formation', -33.923036, 151.259052, 5], ['Cronulla Formation', -34.028249, 151.157507, three], ['Manly Formation', -33.80010128657071, 151.28747820854187, 2], ['Maroubra Formation', -33.950198, 151.259302, 1] ]; I merely privation to game each of these factors and person an `infoWindow` popular ahead once clicked to show the sanction.
This is the easiest I may trim it to:
