Google Maps API V3在信息窗口中显示持续时间和距离

标签: javascript google-maps google-maps-api-3

我已经构建了一个自定义地图,用于构建从单个点到点击标记的路线,但是我无法确定如何在信息窗口中显示总距离和行程持续时间。

function initMap() {
    var directionsService = new google.maps.DirectionsService;
    var directionsDisplay;

    directionsDisplay = new google.maps.DirectionsRenderer({
        polylineOptions: {
            strokeColor: "red"
        }
    });

    var map = new google.maps.Map(document.getElementById('map'), {
        zoom: 13,
        center: new google.maps.LatLng(25.03086141, -77.39945412),
        mapTypeId: google.maps.MapTypeId.ROADMAP
    });

    directionsDisplay.setMap(map);

    var locations = [

您需要根据路线响应中的数据计算总距离和时间。相关问题:Distance from point A to B using Google Maps, PHP and MySQL(我的答案,不是接受的答案,那样做。)

计算总距离和时间:

function computeTotals(result, infowindow) {
  var totalDist = 0;
  var totalTime = 0;
  var myroute = result.routes[0];
  for (i = 0; i < myroute.legs.length; i++) {
    totalDist += myroute.legs[i].distance.value;
    totalTime += myroute.legs[i].duration.value;
  }
  totalDist = totalDist / 1000.
  infowindow.setContent(infowindow.getContent()+"<br>total distance=" + totalDist.toFixed(2) + " km (" + (totalDist * 0.621371).toFixed(2) + " miles)<br>total time=" + (totalTime/60).toFixed(2) + " minutes");
}

调用它并将总距离和时间放在infowindow中:

function calculateAndDisplayRoute(directionsService, directionsDisplay, distinationOrigin, destinationMarker, infowindow) {
  directionsService.route({
    origin: distinationOrigin,
    destination: destinationMarker,
    travelMode: google.maps.TravelMode.DRIVING
  }, function(response, status) {
    if (status === google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response);
      computeTotals(response, infowindow);
    } else {
      window.alert('Directions request failed due to ' + status);
    }
  });
}
