Issue With Infowindows With Multiple Markers And Directionsdisplay Variables In Google Maps Api V3

I'm trying to display how distance and how minutes are between two markers in Google Maps API v3 and use these information to override the default infoWindow text that appears when

Solution 1:

You want to open the infowindow in the DirectionsService callback function where the data is available.

(you may also want to suppress the existing markers from the directions service)

InfoWindow click listener:

    google.maps.event.addListener(marker, 'click', (function(marker, i) {
        returnfunction() {
            calcRoute(locations[i][1], locations[i][2]);
            infowindow.open(map, marker);
        }
    })(marker, i));

Updated calcRoute function:

functioncalcRoute(latdest, lngdest) {
    var start = new google.maps.LatLng(-23.571064, -46.645424);
    var end = new google.maps.LatLng(latdest, lngdest)
    var request = {
        origin: start,
        destination: end,
        travelMode: google.maps.TravelMode.DRIVING
    };
    directionsService.route(request, function (result, status) {
        if (status == google.maps.DirectionsStatus.OK) {
            directionsDisplay.setDirections(result);
            infowindow.setContent(directionsDisplay.directions.routes[0].legs[0].distance.text + " - " + directionsDisplay.directions.routes[0].legs[0].duration.text);
        }
    });
}

code snippet:

var directionsDisplay = new google.maps.DirectionsRenderer({
  map: map,
  suppressMarkers: true
});
var directionsService = new google.maps.DirectionsService();
var map;
var infowindow = new google.maps.InfoWindow();

functioninitMap(locations) {
  functioncalcRoute(latdest, lngdest) {
    var start = new google.maps.LatLng(-23.571064, -46.645424);
    var end = new google.maps.LatLng(latdest, lngdest)
    var request = {
      origin: start,
      destination: end,
      travelMode: google.maps.TravelMode.DRIVING
    };
    directionsService.route(request, function(result, status) {
      if (status == google.maps.DirectionsStatus.OK) {
        directionsDisplay.setDirections(result);
        infowindow.setContent(directionsDisplay.directions.routes[0].legs[0].distance.text + " - " + directionsDisplay.directions.routes[0].legs[0].duration.text);
      }
    });
  }
  map = new google.maps.Map(document.getElementById('mapcanvas'), {
    zoom: 10,
    center: new google.maps.LatLng(-23.571064, -46.645424),
    mapTypeId: google.maps.MapTypeId.ROADMAP
  });
  directionsDisplay.setMap(map);

  var marker, i;
  var image = null;
  for (i = 0; i < locations.length; i++) {
    marker = new google.maps.Marker({
      position: new google.maps.LatLng(locations[i][1], locations[i][2]),
      map: map
    });

    google.maps.event.addListener(marker, 'click', (function(marker, i) {
      returnfunction() {
        calcRoute(locations[i][1], locations[i][2]);
        infowindow.open(map, marker);
      }
    })(marker, i));
  }
}
google.maps.event.addDomListener(window, 'load', function() {
  initMap([
    ["Vila Noemia", -23.670237, -46.467286],
    ["Osasco", -23.535465, -46.794234],
    ["Guarulhos", -23.458911, -46.526912]
  ]);
});
