Question

我正在尝试从网址获取纬度和经度变量，并将它们分配给＆＃39;中心＆＃39; Google地图的属性。我没有收到任何错误，但我提醒我的中心对象到屏幕，并且两者都是“拉”。和＆＃39; lon＆＃39;来了。

以下是网页：http://alainwebdesign.ca/pl4#/49.2/-122.6

Javascript：

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



  .config(function ($stateProvider) {
      $stateProvider.state('location', {
          url: '/:lat/:lon',
          templateUrl: 'searchRadius.html',
          controller: 'MapsCtrl',

          resolve: {
              resolveMap: function (MapService, $stateParams) {
                  return MapService.getData($stateParams.lat, $stateParams.lon);
              }
          }
      });

  })

  .config(['uiGmapGoogleMapApiProvider', function (GoogleMapApi) {
      GoogleMapApi.configure({

          v: '3',

Answer 1

您的问题是您没有使用<ui-view>并且使用ng-controller在页面中拥有该路线的模板。

然后使用index.html作为路径的模板。

实际上，您有2个控制器实例，并且根本没有正确设置应用程序

在index.html中运行的主要ng-controller实例将运行，无论路由如何，以及它为什么不等待$ stateParams或路由更改

根据路由器文档使用自己的模板设置页面，并在index.html中仅设置<ui-view>

$ stateParams返回null对象
