Answer 1

如上所述，您需要关闭:

for (loc in locations){
  (function(loc){  
    var newLoc = locations[loc].split(", ")
    var uniquevar = new google.maps.Marker({
      position: new google.maps.LatLng(newLoc[0], newLoc[1]),
      map: map,
     title: loc
    });

    google.maps.event.addListener(loc, 'click', function() {
      console.log(loc);
    });
  })(loc);
};
