Ho lavorato con una fabbrica integrata con il completamento automatico di Google Maps e le promesse fatte, spero che tu serva.
http://jsfiddle.net/the_pianist2/vL9nkfe3/1/
devi solo sostituire il servizio di completamento automatico con questa richiesta con $ http incuida prima della fabbrica.
app.factory('Autocomplete', function($q, $http) {
e $ http richiesta con
var deferred = $q.defer();
$http.get('urlExample').
success(function(data, status, headers, config) {
deferred.resolve(data);
}).
error(function(data, status, headers, config) {
deferred.reject(status);
});
return deferred.promise;
<div ng-app="myApp">
<div ng-controller="myController">
<input type="text" ng-model="search"></input>
<div class="bs-example">
<table class="table" >
<thead>
<tr>
<th>#</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="direction in directions">
<td>{{$index}}</td>
<td>{{direction.description}}</td>
</tr>
</tbody>
</table>
</div>
'use strict';
var app = angular.module('myApp', []);
app.factory('Autocomplete', function($q) {
var get = function(search) {
var deferred = $q.defer();
var autocompleteService = new google.maps.places.AutocompleteService();
autocompleteService.getPlacePredictions({
input: search,
types: ['geocode'],
componentRestrictions: {
country: 'ES'
}
}, function(predictions, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
deferred.resolve(predictions);
} else {
deferred.reject(status);
}
});
return deferred.promise;
};
return {
get: get
};
});
app.controller('myController', function($scope, Autocomplete) {
$scope.$watch('search', function(newValue, oldValue) {
var promesa = Autocomplete.get(newValue);
promesa.then(function(value) {
$scope.directions = value;
}, function(reason) {
$scope.error = reason;
});
});
});
la domanda stessa deve essere fatta su:
deferred.resolve(varResult);
quando hai fatto bene e la richiesta:
deferred.reject(error);
quando si verifica un errore, quindi:
return deferred.promise;
