完全披露:我是JS的新手,也是AngularJs的新手。随着那说......
我正在尝试创建一个使用AngularJs的Web应用程序。路由提供商功能。我想使用其中一个templateURL来包含一个Google Map对象,我可以动态地添加标记等,因为后端服务器可以提供数据。
我的工作:
ui-gmap-google-map
元素的模板网址,并在控制器内部为模板网址添加了一个回调,我通过uiGmapGoogleMapApi.then
添加了一个被调用的回调(地图可见)。缺少什么:
control
作为HTML标记的一部分(请参阅下面的map.html
文件)并看到this promising answer似乎解决我的确切问题。但是,我的$scope.map.control
对象永远不会被填写(有关详细信息,请参见下文)。我的设置如下:
webapp
--css
--style.css // contains ".angular-google-map-container {height: 400px;}"
--js
--angular-google-maps.min.js
--angular-simple-logger.js
--lodash.min.js
--pages
--about.html // from tutorial
--contact.html // from tutorial
--home.html // from tutorial
--map.html // my map is in here (see below)
--WEB-INF
--web.xml
--index.html // modified from the tutorial (see below)
--script.js // modified from the tutorial (see below)
我的新/更改文件如下:
页/ map.html
<div>
<ui-gmap-google-map center='map.center' zoom='map.zoom' control='map.control'></ui-gmap-google-map>
</div>
index.html(主要是教程代码)
<!DOCTYPE html>
<html ng-app="scotchApp">

</html>
最后是script.js
// create the module and name it scotchApp
var scotchApp = angular.module('scotchApp', ['ngRoute', 'uiGmapgoogle-maps']);
scotchApp.config(function($routeProvider) {
$routeProvider
// ...
// Skipping unrelated routing code from the tutorial
// ...
// route for the map page (THIS IS NEW)
.when('/map', {
templateUrl : 'pages/map.html',
controller : 'mapController'
});
}).config(function (uiGmapGoogleMapApiProvider) {
uiGmapGoogleMapApiProvider.configure({
key: '{KEY IS HERE}',
v: '3.20',
libraries: 'weather,geometry,visualization'
});
});
// ...
// Skipping unrelated controller code from the tutorial
// ...
scotchApp.controller('mapController', function($scope, uiGmapGoogleMapApi) {
// Here is my empty "control" as specified by the documentation
$scope.map = { control: {}, center: { latitude: 45, longitude: -73 }, zoom: 8 };
uiGmapGoogleMapApi.then(function(maps) {
console.log("Maps are ready");
// Here $scope.map.control is still empty. What gives?
if ($scope) {
console.log("Scope is defined");
}
else {
console.log("Scope is not defined");
}
});
});
那么为了让我获得控制权以便我可以调用$scope.map.control.getGMap()
来获取地图(根据文档)会缺少什么?
答案 0 :(得分:1)
似乎当uiGmapGoogleMapApi
承诺得到解决时,并不意味着地图已准备就绪。请尝试使用uiGmapIsReady.promise()
(有关详情,请查看this SO answer)。工作代码:
scotchApp.controller('mapController', function($scope, uiGmapGoogleMapApi, uiGmapIsReady) {
// Here is my empty "control" as specified by the documentation
$scope.map = { control: {}, center: { latitude: 45, longitude: -73 }, zoom: 8 };
uiGmapIsReady.promise().then(function(instances) {
console.log($scope.map.control.getGMap); //is set now
});
});
