javascript - 使用 ngmap 在标记之间创建一条线

Question

我正在使用 ngmap 和 Angular js 在 map 中显示一组标记，没有问题。我需要画一条连接这些标记的线。

我的代码:

查看中:

 <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 Controller 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}];
});

Answer 1

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];
    });
});
