的编码但是我得到的是一个空白的屏幕不知道我错了。请帮助
Im trying to implement a map using google maps with Ionic. I followed the coding in this Link But all i get is a blank screen dont know where i went wrong. Please help
这是控制器
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);
});
};
$scope.clickTest = function() {
alert('Example of infowindow with ng-click')
};
});
这是html文件
<script src="//maps.googleapis.com/maps/api/js?key=AIzaSyB16sGmIekuGIvYOfNoW9T44377IU2d2Es&sensor=true"></script>
<body ng-controller="MapCtrl">
<ion-header-bar class="bar-dark" >
<h1 class="title">Map</h1>
</ion-header-bar>
<ion-content>
<div id="map" data-tap-disabled="true"></div>
</ion-content>
<ion-footer-bar class="bar-dark">
<a ng-click="centerOnMe()" class="button button-icon icon ion-navigate">Find Me</a>
</ion-footer-bar>
</body>
请帮助。
推荐答案
我改变了一些东西让这个工作：
I changed a few things to get this to work:
你不需要一个api键谷歌地图了，脚本src（请参阅 Google是什么Maps API Key ）：
You don't need an api key for google maps anymore, this is enough for the script src (see Whats the Google Maps API Key):
<script src="//maps.googleapis.com/maps/api/js?sensor=false"></script>
用$ scope.init（）替换function initialize（）并注释掉行
Replace "function initialize()" with "$scope.init()" and comment out the line where it sais:
//google.maps.event.addDomListener(window, 'load', initialize);
同样将ng-init =init（）添加到您的html中：
Also add ng-init="init()" to your html like this:
<ion-header-bar class="bar-dark" ng-init="init()">
<h1 class="title">Map</h1>
</ion-header-bar>
我不知道为什么它不使用domListener，但是数据需要先被初始化显示它们（请参阅 Google MAP API Uncaught TypeError：无法读取属性offsetWidth为null ）。使用ng-init可以实现这一点。
I don't know why it's not working with the domListener, but the data need to be initialized before displaying them (see Google MAP API Uncaught TypeError: Cannot read property 'offsetWidth' of null). With ng-init you can achieve this.
最终控制器应如下所示：
Final controller should look like this:
.controller('MapCtrl', function($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')
};
});
