我正在尝试从URL获取纬度和经度变量,并将它们分配给Google Maps的'center'属性。我没有收到任何错误,但我向屏幕提醒了中心对象,并且“ lat”和“ lon”都为空。
这是网页: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, $stateParams.lon);
}
}
});
})
.config(['uiGmapGoogleMapApiProvider', function (GoogleMapApi) {
GoogleMapApi.configure({
key: 'AIzaSyCbRPhVlxgVwBC0bBOgyB-Dn_K8ONrxb_g',
v: '3',
libraries: 'weather,geometry,visualization'
});
} ])
.controller('MapsCtrl', ['$scope', "uiGmapLogger", "uiGmapGoogleMapApi", "$interval", "$state", "$stateParams",
function ($scope, $log, GoogleMapApi, $interval, $state, $stateParams) {
$log.currentLevel = $log.LEVELS.debug;
var center = { latitude: parseFloat($stateParams.lat), longitude: parseFloat($stateParams.lon) };
alert(JSON.stringify(center));
//Object.freeze(center); caused TypeError: Cannot assign to read only property ('latitude') ...
console.log($stateParams);
$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);

最佳答案
您的问题是您没有使用<ui-view>
,而是在页面中使用ng-controller
使用了该路由的模板。
然后,使用index.html作为路由的模板。
实际上,您有2个控制器实例,并且有关路由的应用程序设置不正确
在index.html中运行的主要ng-controller实例将与路由无关地运行,这就是为什么它不等待$ stateParams或路由更改的原因
使用路由器自己的模板,按照路由器文档设置页面,在index.html中仅<ui-view>
关于javascript - $ stateParams返回空对象,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/39883370/
