Using a factory to pass data from one controller to another controller in AngularJS
Question
I'm trying to take in the longitude and latitude values (using the google maps API) from one controller, and sending it to another controller. To do this, I'm using a factory. However, there seems to be a problem with either sending the information into the factory, or reading from it.
.factory('loc', function(){
var location = {};
return {
setProperty: function(latitude, longitude){
location.lat = latitude;
location.lng = longitude;
},
getProperty: function(){
return location;
}
};
});
The first controller (google maps)
.controller('MapCtrl', function($scope, $ionicLoading,loc) {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(pos) {
loc.setProperty(pos.coords.latitude, pos.coords.longitude)
...
In the second controller, I have:
.controller('callCtrl', function($scope,$state,loc) {
$scope.updateTask = function(data) {
task.location_lng = loc.getProperty().lng;
task.location_lat = loc.getProperty().lat;
...

}
$scope.getLocation = function() {
alert(JSON.stringify(loc.getProperty()));

$scope.clearLocation = function() {
loc.setProperty( "", "")

app.factory('loc', function() {

This Works:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,loc) {
loc.setProperty(10,20);
});
app.controller('SubCtrl', function($scope,loc) {
$scope.updateData = function(){
//this is the change
$scope.lat = loc.getProperty().lat;
$scope.lng = loc.getProperty().lng;
}
});
app.factory('loc', function() {
var location = {};
return {
setProperty: function(latitude, longitude) {
location.lat = latitude;
location.lng = longitude;
},
getProperty: function() {
return location;
}
};
});
