我有一个在$ scope.mapCreated上正常工作的标记。现在,我试图在用户单击$ scope.centerOnMe()时显示另一个标记,但仅显示当前位置而不显示标记。
我必须使用此示例还是有最简单的解决方案?
控制器
.controller('mapCtrl', ['$scope', '$state', '$ionicLoading', function($scope, $state, $ionicLoading){
$scope.mapCreated = function(map) {
var latlngPlace = new google.maps.LatLng(-27.4264356, -51.7838787);
var marker = new google.maps.Marker({
map: map,
position: latlngPlace
});
$scope.map = map;
};
$scope.centerOnMe = function () {
console.log("Centering");
if (!$scope.map) {
return;
}
$scope.loading = $ionicLoading.show({
content: 'Wait...',
showBackdrop: false
});
navigator.geolocation.getCurrentPosition(function (pos) {
console.log('Got pos', pos);
$scope.map.setCenter(new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude));
var myPlace = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
var marker2 = new google.maps.Marker({
position: myPlace
});
$ionicLoading.hide();
}, function (error) {
console.log('Error' + error.message)
});
};
}])
指令.js
angular.module('app.directives', [])
.directive('map', function(){
return {
restrict: 'E',
scope: {
onCreate: '&'
},
link: function ($scope, $element, $attr) {
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-27.426102, -51.784999),
zoom: 16,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map($element[0], mapOptions);
$scope.onCreate({map: map});
// Stop the side bar from dragging when mousedown/tapdown on the map
google.maps.event.addDomListener($element[0], 'mousedown', function (e) {
e.preventDefault();
return false;
});
}
if (document.readyState === "complete") {
initialize();
} else {
google.maps.event.addDomListener(window, 'load', initialize);
}
}
}
});
map.html
<ion-view title="Map" id="page9" style="background-color:#FFFFFF;">
<ion-content>
<map on-create="mapCreated(map)"></map>
</ion-content>
<ion-footer-bar class="bar-stable bar-calm">
<a ng-click="centerOnMe()" class="button button-icon icon ion-navigate">FindMe</a>
</ion-footer-bar>
</ion-view>
它只是缺少地图:$ scope.map
var myPlace = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
var marker2 = new google.maps.Marker({
map: $scope.map,
position: myPlace
});
