【问题标题】:Connect Multiple markers with polyline用折线连接多个标记
【发布时间】:2017-04-08 08:16:15
【问题描述】:

我尝试了这段代码,但折线没有运气,可能是因为小问题,我无法获得连接标记的折线。
我需要用折线连接多个标记,也欢迎使用任何替代代码。

var locations = [];
// call php array
var latitude = <?php echo json_encode($latitude); ?>;
var longitude = <?php echo json_encode($longitude); ?>;
for(var i=0;i<20;i++){
 locations.push(["current",latitude[i], longitude[i]]);
}

var marker;
          function initMap() {
           var map = new google.maps.Map(document.getElementById('map'), {
          zoom: 5,
          center: new google.maps.LatLng(12.289774217827633, 76.30976921188685)
          });

var flightPath = new google.maps.Polyline({
                                            path: locations,
                                            geodesic: true,
                                            strokeColor: '#000000',
                                            strokeOpacity: 1.0,
                                            strokeWeight: 3
  });


flightPath.setMap(map);
 var infowindow = new google.maps.InfoWindow();
 var marker, i;

    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) {
        return function() {
          infowindow.setContent(locations[i][0]);
          infowindow.open(map, marker);
        }
      })(marker, i));
    }
}

    【解决方案1】:

    flightPath 应该被称为数组。

    请试试这个更新的代码。

    var locations = [
    
       ];
    
    // call php array
     var latitude = <?php echo json_encode($latitude); ?>;
     var longitude = <?php echo json_encode($longitude); ?>;
    for(var i=0;i<20;i++){
     locations.push(["current",latitude[i], longitude[i]]);
    }
    var marker;
         function initMap() {
           var map = new google.maps.Map(document.getElementById('map'), {
             zoom: 5,
             center: new google.maps.LatLng(12.289774217827633, 76.30976921188685)
           });
    
    
    // locations.push(["current",test2, test3]);
     var infowindow = new google.maps.InfoWindow();
    
     var marker, i;
    var flightPlanCoordinates = [];
    
       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
         });
    flightPlanCoordinates.push(marker.getPosition());
         google.maps.event.addListener(marker, 'click', (function(marker, i) {
           return function() {
             infowindow.setContent(locations[i][0]);
             infowindow.open(map, marker);
           }
         })(marker, i));
       }
       var flightPath = new google.maps.Polyline({
         map: map,
         path: flightPlanCoordinates,
         strokeColor: "#ff0000",
    
         strokeOpacity: 1.0,
         strokeWeight: 2
       });
    }
