Angular-UI typeahead results not showing in dropdown

Question

Im using Angular-ui typeahead component to hit an autocomplete API, and I'm parsing the data I get back into an array called resp. However, Im not seeing the data getting passed to the autocomplete dropdown in the UI. BTW, the controller has a console.log that displays the data correctly, so i know its returning from the api call.

Here is my controller function:

$scope.getLocationForSearch = function(locationString){

    $scope.locationString = locationString;
    var url = '/autoComplete/' + locationString ;
    $http({
        method: 'GET',
        url: url            
    }).then(function successCallback(response) {
        console.clear();
        var resp = response.data.RESULTS.map(function(item){
            console.log(item.name);
            return item.name;
        });

        return resp;

      }, function errorCallback(response) {
        console.log(response); 
    });     
}

and in my HTML:

    <div class="input-group">
        <input 
            type="text" class="form-control" ng-model="asyncSelected" placeholder="Search city or zip code"
            uib-typeahead="item for item in getLocationForSearch($viewValue)"/>
        <i ng-show="loadingLocations" class="glyphicon glyphicon-refresh"></i>
        <div ng-show="noResults">
          <i class="glyphicon glyphicon-remove"></i> No Results Found
        </div>
        <span class="input-group-btn">
            <button class="btn btn-default" name="search" ng-model="asyncSelected" type="submit" ng-click="getWeather(asyncSelected)">
                <span class="glyphicon glyphicon-search" aria-hidden="true"></span>
            </button>
        </span>
    </div><!-- /input-group -->

There are several posts on here for this same issue but none really answer my specific problem. Any help is appreciated.

Answer 1

Your function getLocationForSearch() is not good: it has to return a promise to uib-typeahead directive. So working code is:

  $scope.getLocationForSearch = function(locationString) {

    $scope.locationString = locationString;
    var url = '/autoComplete/' + locationString ;

    return $http({
      method: 'GET',
      url: url
    }).then(function successCallback(response) {
      console.clear();
      return response.data.results.map(function(item) {
        console.log(item.name);
        return item.name;
      });
    }, function errorCallback(response) {
      console.log(response);
    });
  }
