Question

我正在使用ngmap和angular js在地图中显示一组标记而没有问题。我需要画一条连接这些标记的线。

我的代码：

在视图中：

 <map center="{{markers[0].lat}},{{markers[0].lng}}" zoom="12">
   <marker ng-repeat="pos in markers" position="{{pos.lat}}, {{pos.lng}}"></marker>
</map>

在我的控制器中：

var app = angular.module('Items', ['ngMap'])

app.controller('CICtrl', function($scope){
    $scope.markers = [{id:1, lat:37.772323, lng: -122.214897}, {id:2, lat:21.291982, lng: -157.821856}, {id:3, lat:-27.46758, lng: 153.027892}];
});

为此，您可以使用shape指令，例如：

<shape name="polyline" path="{{path}}" geodesic="true" stroke-color="#FF0000" stroke-opacity="1.0" stroke-weight="2"></shape>

其中path属性是从markers初始化的，如下所示：

$scope.path = $scope.markers.map(function(marker){
    return [marker.lat,marker.lng];
});

工作示例

var app = angular.module('appMaps', ['ngMap']);
app.controller('mainCtrl', function ($scope) {
    $scope.markers = [{ id: 1, lat: 37.772323, lng: -122.214897 }, { id: 2, lat: 21.291982, lng: -157.821856 }, { id: 3, lat: -27.46758, lng: 153.027892 }];
    $scope.path = $scope.markers.map(function(marker){
        return [marker.lat,marker.lng];
    });
});

            <shape name="polyline" path="{{path}}" geodesic="true" stroke-color="#FF0000" stroke-opacity="1.0" stroke-weight="2">
            </shape>
        </map>
</div>

对于那些希望在标记之间显示行车路线并自定义每个标记之间线条外观的人：

工作范例：

在您的控制器中：

$scope.directions = [
  {
    origin:"Salt Lake City, Utah", 
    destination:"West Valley City, Utah", 
    panelName:"p1",
    renderingOptions: {
      polylineOptions: {
        strokeColor: 'red'
      }      
    },
    wayPoints: [
      {
        location: {lat:40.6812675, lng: -111.9622787},
        stopover: true
      },
      {
        location: {lat:40.6812675, lng: -110.9622787},
        stopover: true
      },
    ]
  },
  {
    origin:"West Valley City, Utah", 
    destination:"West Jordan, Utah", 
    panelName:"p1",
    renderingOptions: {
      polylineOptions: {
        strokeColor: 'blue'
      }      
    },
    wayPoints: [
      {
        location: {lat:40.6812675, lng: -111.9622787},
        stopover: true
      },
      {
        location: {lat:40.6812675, lng: -109.9622787},
        stopover: true
      },
    ]
  },
  {
    origin:"West Jordan, Utah", 
    destination:"Salt Lake City, Utah", 
    panelName:"p2",
    renderingOptions: {
      polylineOptions: {
        strokeColor: 'green'
      }      
    },
    wayPoints: [
      {
        location: {lat:40.6812675, lng: -111.9622787},
        stopover: true
      },
      {
        location: {lat:40.6812675, lng: -108.9622787},
        stopover: true
      },
    ]
  }
];

HTML：传递表格的对象：

renderingOptions: {polylineOptions: {strokeColor: 'red'}}

进入<directions>元素的选项属性

          <div style="width: 100%; float:left; height:70%" >     
            <ng-map zoom="3" center="current-location" default-style="false" style="height: 450px; display:block; ">
                <directions ng-repeat="dir in directions"
                  draggable="true"
                  options="{{dir.renderingOptions}}"
                  travel-mode="DRIVING"
                  waypoints="{{dir.wayPoints}}"
                  panel="{{dir.panelName}}"
                  origin="{{dir.origin}}"
                  destination="{{dir.destination}}">
                </directions>            
            </ng-map>
          </div>

使用ngmap
