我曾与一家集成了谷歌地图自动完成和承诺的工厂合作过,我希望你能服务。

您只需要在工厂之前使用 $ http incuida 替换此请求的 autocompleteService 即可。
app.factory('Autocomplete', function($q, $http) {
和 $ http 请求
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;
});
});
});
问题本身将针对:
deferred.resolve(varResult);
当你做得很好并且请求:
deferred.reject(error);
当出现错误时,然后:
return deferred.promise;
