我正在尝试使用带有 Ionic 的谷歌地图来实现 map 。我遵循了这个 Link 中的编码
但我得到的只是一个空白屏幕，不知道我哪里出错了。请帮忙
这是 Controller
angular.module('starter', ['ionic'])
.controller('MapCtrl', function($scope, $ionicLoading, $compile) {
function initialize() {
var myLatlng = new google.maps.LatLng(43.07493,-89.381388);
var mapOptions = {
center: myLatlng,
zoom: 16,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
//Marker + infowindow + angularjs compiled ng-click
var contentString = "<div><a ng-click='clickTest()'>Click me!</a></div>";
var compiled = $compile(contentString)($scope);
var infowindow = new google.maps.InfoWindow({
content: compiled[0]
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Uluru (Ayers Rock)'
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
$scope.map = map;
}
google.maps.event.addDomListener(window, 'load', initialize);
$scope.centerOnMe = function() {
if(!$scope.map) {
return;
}
$scope.loading = $ionicLoading.show({
content: 'Getting current location...',
showBackdrop: false
});
navigator.geolocation.getCurrentPosition(function(pos) {
$scope.map.setCenter(new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude));
$scope.loading.hide();
}, function(error) {
alert('Unable to get location: ' + error.message);
});
};
$scope.clickTest = function() {
alert('Example of infowindow with ng-click')
};
});
这是html文件
<script src="//maps.googleapis.com/maps/api/js?key=AIzaSyB16sGmIekuGIvYOfNoW9T44377IU2d2Es&sensor=true"></script>
<body ng-controller="MapCtrl">
<ion-header-bar class="bar-dark" >
<h1 class="title">Map</h1>
</ion-header-bar>
<ion-content>
<div id="map" data-tap-disabled="true"></div>
</ion-content>
<ion-footer-bar class="bar-dark">
<a ng-click="centerOnMe()" class="button button-icon icon ion-navigate">Find Me</a>
</ion-footer-bar>
</body>
请帮忙。
最佳答案
我改变了一些事情来让它工作:
谷歌地图不再需要 api key ，这对于脚本 src 来说已经足够了(参见 Whats the Google Maps API Key):
<script src="//maps.googleapis.com/maps/api/js?sensor=false"></script>
将“function initialize()”替换为“$scope.init()”并注释掉它所在的行:
//google.maps.event.addDomListener(window, 'load', initialize);
还将 ng-init="init()"添加到您的 html 中，如下所示:
<ion-header-bar class="bar-dark" ng-init="init()">
<h1 class="title">Map</h1>
</ion-header-bar>
我不知道为什么它不能与 domListener 一起使用，但是在显示它们之前需要初始化数据(参见 Google MAP API Uncaught TypeError: Cannot read property 'offsetWidth' of null )。使用 ng-init 你可以实现这一点。
最终 Controller 应如下所示:
.controller('MapCtrl', function($scope, $ionicLoading, $compile) {
$scope.init = function() {
var myLatlng = new google.maps.LatLng(43.07493,-89.381388);
var mapOptions = {
center: myLatlng,
zoom: 16,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
//Marker + infowindow + angularjs compiled ng-click
var contentString = "<div><a ng-click='clickTest()'>Click me!</a></div>";
var compiled = $compile(contentString)($scope);
var infowindow = new google.maps.InfoWindow({
content: compiled[0]
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Uluru (Ayers Rock)'
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
$scope.map = map;
};
// google.maps.event.addDomListener(window, 'load', initialize);
$scope.centerOnMe = function() {
if(!$scope.map) {
return;
}
$scope.loading = $ionicLoading.show({
content: 'Getting current location...',
showBackdrop: false
});
navigator.geolocation.getCurrentPosition(function(pos) {
$scope.map.setCenter(new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude));
$scope.loading.hide();
}, function(error) {
alert('Unable to get location: ' + error.message);
});
};
$scope.clickTest = function() {
alert('Example of infowindow with ng-click')
};
});
希望这有帮助!
