Troubleshooting issues with data parsing in an Angular typeahead module

Utilizing the AngularJS Bootstrap typeahead module, I am attempting to showcase data from an array of objects. Despite receiving data from my API call, I keep encountering the following error:

TypeError: Cannot read property 'length' of undefined

This is the current state of the controller:

$scope.companySearch = function(val) {
    LeadsService.getCompany(val)
        .then(function(resp) {
            return resp.resp;
        });
};

And here is the directive:

<input typeahead="company as item.company_name for item in companySearch($viewValue)" id="companyName" name="company_name" type="text" class="form-control input-md" ng-model="companyDetails.company_name" typeahead-wait-ms="200" required>

Lastly, this is the data I am trying to retrieve:

[{"id":2,"company_name":"Test Company","address1":"abc","address2":"def","po_box":"1234","city_id":2,"email":"example@example.com","phone":"9898","fax_no":9798,"website":"www.example.com","corporate_code":null,"contact_person_first_name":"First","contact_person_last_name":"Last","contact_person_phone":"98989","contact_person_email":"example@example.com"}]

If it provides any insight, the error occurs before my promise is fulfilled.

Answer №1

If you're looking to asynchronously load data for Typeahead, give this code a try:

$scope.companySearch = function(val) {
    return LeadsService.getCompany(val)
        .then(function(response) {
            return response.data;
        });
};

Answer №2

Give this a shot:

$scope.searchCompany = function(value) {
    return LeadsService.fetchCompany(value)
        .then(function(response) {
            return response.data;
    });
};

This function sends the promise directly to the typeahead directive. The typeahead will patiently wait for the data to be retrieved.
