Question

我正在尝试使用$ stateParams（纬度和经度）在URL中获取两个浮点变量，并将它们分配给Google Map＆＃39; center＆＃39;宾语。纬度和经度最终都是空值，我认为它与这一行有关：

var center = { latitude: parseFloat($stateParams.lat), longitude: parseFloat($stateParams.lon) };

这是页面，因此您可以看到警告，其中显示JSON.stringify（center）：http://alainwebdesign.ca/pl4/#/49.2/-122.6

这是我的JS文件：

(function (window, ng) {
    ng.module('app', ['uiGmapgoogle-maps', 'ui.router'])



  .config(function ($stateProvider) {
      $stateProvider.state('location', {
          url: '/:lat/:lon',
          templateUrl: 'index.html',
          controller: 'MapsCtrl',
          params: { //set default values (not sure if it does anything)
              lat: '80', 
              lon: '-122'
          },
          resolve: {
              resolveMap: function (MapService, $stateParams) {
                  return MapService.getData($stateParams.lat, $stateParams.lon);
              }
          }
      });

  })

  .config(['uiGmapGoogleMapApiProvider', function (GoogleMapApi) {
      GoogleMapApi.configure({
          key: 'AIzaSyCbRPhVlxgVwBC0bBOgyB-Dn_K8ONrxb_g',
          v: '3',
          libraries: 'weather,geometry,visualization'
      });
  } ])


    .controller('MapsCtrl', ['$scope', "uiGmapLogger", "uiGmapGoogleMapApi", "$interval", "$state", "$stateParams",
      function ($scope, $log, GoogleMapApi, $interval, $state, $stateParams) {
          $log.currentLevel = $log.LEVELS.debug;

//Is this center variable using $stateParams correctly?
          var center = { latitude: parseFloat($stateParams.lat), longitude: parseFloat($stateParams.lon) };
          alert(JSON.stringify(center));
          //Object.freeze(center); caused TypeError: Cannot assign to read only property ('latitude') ...

          $scope.map = {
              center: center,
              pan: false,
              zoom: 16,
              refresh: false,
              events: {},
              bounds: {}
          };

          $scope.map.circle = {
              id: 1,
              center: center,
              radius: 500, //(current time - date lost)*km/hour
              stroke: {
                  color: '#08B21F',
                  weight: 2,
                  opacity: 1
              },

              fill: {
                  color: '#08B21F',
                  opacity: 0.5
              },
              geodesic: false, // optional: defaults to false
              draggable: false, // optional: defaults to false
              clickable: true, // optional: defaults to true
              editable: false, // optional: defaults to false
              visible: true, // optional: defaults to true
              events: {
                  dblclick: function () {
                      $log.debug("circle dblclick");
                  },
                  radius_changed: function (gObject) {
                      var radius = gObject.getRadius();
                      $log.debug("circle radius radius_changed " + radius);
                  }
              }
          }





          //Increase Radius:
          $interval(function () {
              $scope.map.circle.radius += 30; //dynamic var
              $state.transitionTo('location', { //location is the state name
                  center: $stateParams.center,
                  radius: $scope.map.circle.radius
              },
    {
        notify: false
    });
          }, 1000); //end of interval function


      } ]); //end of controller

})(window, angular);
