我在 angularjs 应用程序中使用ngMap
。
我正在显示带有多个标记的谷歌地图，onclick of Open map! button并且地址数组中存在第一个地址，我将其作为地图中心。
这是Plunk
例子.js：
angular.module('plunker', ['ui.bootstrap', 'ngMap']);
var ModalDemoCtrl = function ($scope, $modal, $log) {
$scope.displayMap = function () {
$scope.addresses = [{ "address": "Hyderabad" },
{ "address": "Chennai" },
{ "address": "Bangalore" },
{ "address": "Kolkata" },];
$scope.latlng = [];
$scope.loop(0, $scope.addresses)
}
$scope.loop = function (id, addressesresult) {
if (id < addressesresult.length) {
var address = addressesresult[id].address;
geocoder = new google.maps.Geocoder();
geocoder.geocode({
'address': address
}, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
$scope.latlng.push({
"lat": results[0].geometry.location.lat(),
"lng": results[0].geometry.location.lng(),
"title": results[0].formatted_address
});
if (id == ((addressesresult.length) - 1)) {
$scope.openPopup();
}
} else {
console.log('Geocode was not successful for the following reason:' + status);
}
id = id + 1;
$scope.loop(id, addressesresult);
});
}
}
$scope.openPopup = function () {
var modalInstance = $modal.open({
templateUrl: 'modal1',
controller: ModalInstanceCtrl,
scope: $scope,
resolve: {
lat: function () {
return $scope.latlng[0].lat;
},
lng: function () {
return $scope.latlng[0].lng;
},
latlng: function () {
return $scope.latlng;
}
}
});
};
};
// Please note that $modalInstance represents a modal window (instance) dependency.
// It is not the same as the $modal service used above.
var ModalInstanceCtrl = function ($scope, $modalInstance, lat, lng) {
$scope.lat = lat;
$scope.lng = lng;
$scope.render = true;
$scope.close = function () {
$modalInstance.close();
};
};

所有与地址相关的标记都显示正常。
但是如何为地址数组自动设置最佳缩放，这里这些地址是我从数据库中获取的，所以这些地址会根据某些条件针对每个请求进行更改。
