angular js autocomplete key value array

Question

I looked at the autocomplete example in: http://jsfiddle.net/sebmade/swfjT/ How can i make an auto complete to key value array? This is my array:

$countryCodesToCountryNames = array(
"AD" => "Andorra",
"AE" => "United Arab Emirates",
"AF" => "Afghanistan",
"AG" => "Antigua and Barbuda",
"AI" => "Anguilla",
"AL" => "Albania",
"AM" => "Armenia",
"AO" => "Angola",
"AQ" => "Antarctica",
"AR" => "Argentina",
"AS" => "American Samoa",
"AT" => "Austria",
"AU" => "Australia",
"AW" => "Aruba",
"AX" => "Åland Islands",
"AZ" => "Azerbaijan",
"BA" => "Bosnia and Herzegovina",
"BB" => "Barbados",
"BD" => "Bangladesh",
"BE" => "Belgium",
"BF" => "Burkina Faso",
"BG" => "Bulgaria",
"BH" => "Bahrain",
"BI" => "Burundi",
"BJ" => "Benin",
"BL" => "Saint Barth,élemy",
"BM" => "Bermuda",
"BN" => "Brunei Darussalam",
"BO" => "Bolivia, Plurinational State of",
"BQ" => "Bonaire, Sint Eustatius and Saba",
"BR" => "Brazil",
"BS" => "Bahamas",
"BT" => "Bhutan",
"BV" => "Bouvet Island",
"BW" => "Botswana",
"BY" => "Belarus",
"BZ" => "Belize",
"CA" => "Canada");

I need that the autocomplete input field will present the country name(array value), But when selected(on-click) i'll get the country code(array key) to the angular controller.

what is the code changes needed in the example above?

Answer 1

I did an example for this case using another kind of array.

I changed in this way the array

$scope.selectedCountry = '';
$scope.countryCodesToCountryNames = [
         {'code':'AD', 'name': 'Andorra'},
         {'code':'BZ', 'name': 'Belize'},
         {'code':'CA', 'name': 'Canada'}];

in your html you put this code

                 <blockquote>
                  CODE: {{selectedCountry.code}}<br/>                  
                  NAME: {{selectedCountry.name}}<br/>                  
                </blockquote>
                Select Country: <input type="text" ng-model="selectedCountry" typeahead="country as (country.name ) for country in countryCodesToCountryNames | filter:$viewValue" />

This are 3 examples of autocompleted: jsfiddle

HTML Code

<div class="container">
    <div ng-controller="mainCtrl" class="row-fluid">
        <form class="row-fluid">
            <div class="container-fluid"><br/>
                 <blockquote>
                  State: {{selectedState}}<br/>
                </blockquote>

                Select States: <input type="text" ng-model="selectedState" typeahead="state for state in states | filter:$viewValue" />
                <br/>

                <blockquote>
                  ID: {{selectedUser.id}}<br/>
                  Name: {{selectedUser.name + ' ' + selected.last}}<br/>
                  Age: {{selectedUser.age}}<br/>
                  Gender: {{selectedUser.gender}}
                </blockquote>

                Select User: <input type="text" ng-model="selectedUser" typeahead="user as (user.first + ' ' + user.last) for user in users | filter:$viewValue" />

                <br/>

                <blockquote>
                  CODE: {{selectedCountry.code}}<br/>                  
                  NAME: {{selectedCountry.name}}<br/>                  
                </blockquote>
                Select Country: <input type="text" ng-model="selectedCountry" typeahead="country as (country.name ) for country in countryCodesToCountryNames | filter:$viewValue" />
            </div>
        </form>
    </div>
</div>

angular.module('myApp', ['ui.bootstrap'])
    .controller("mainCtrl", function ($scope) {

    $scope.selectedUser = '';
    $scope.users = [
    {'id': 1, 'first': 'John', 'last': 'Depp', 'age':52, 'gender':'male'}, 
    {'id': 2, 'first': 'Sally', 'last': 'JoHanson', 'age':13, 'gender':'female'},

     $scope.selectedCountry = '';
     $scope.countryCodesToCountryNames = [
         {'code':'AD', 'name': 'Andorra'},
