Angular-UI typeahead: show label but bind to value only

I am using Angular-UI typeahead in the following way:

<input type="text" ng-model="myModel" typeahead="o.value as o.text for o in options | filter:$viewValue | limitTo:5" typeahead-editable="false" />

binded to a model like:

var options = [
    {"value": 1, "text": "value1"},
    {"value": 2, "text": "value2"},
    ...
];

It correctly shows options text, but when I select an item it shows inside the textbox the value. The model is correctly bounded to the value only (not the entire model object).

Is it possible to show inside the textbox the "text" (not the "value") after selection, still maintaining model binding to just the value (ie: when I select a certain "text" the model is updated with the "value")?

It's not ideal, but the typeahead-input-formatter attribute provides a work-around until a fix can be provided. (Plunker from github thread).

HTML:

<input type="text" 
       ng-model="myModel" 
       typeahead="o.value as o.text for o in options | filter:$viewValue | limitTo:5" 
       typeahead-editable="false" 
       typeahead-input-formatter="formatLabel($model)" 
/>

AngularJs controller function:

$scope.formatLabel = function(model) {
   for (var i=0; i< $scope.options.length; i++) {
     if (model === $scope.options[i].value) {
       return $scope.options[i].text;
     }
   }
};

Try changing your code from

typeahead="o.value as o.text for o in options | filter:$viewValue | limitTo:5"

to

typeahead="o as o.text for o in options | filter:$viewValue | limitTo:5"

You can try doing as suggested but with typeahead-on-select like so

<input type="text" 
       ng-model="myModel" 
       typeahead="o as o.text for o in options | filter:$viewValue | limitTo:5" 
       typeahead-editable="false" 
       typeahead-on-select="model=$item.value"
/>

This will ensure that the text or label is displayed but underlying value is changed.

Here a shorthand formatter for everybody who uses lodash or underscore:

function formatTypehead(array,id){
  var o = _.find(array,{id:id});
  return (o?o.displayName || id:id);
}

and html:

<input  type="text" 
  uib-typeahead="s.id as s.displayName for s in companies | filter:$viewValue | limitTo:8"
  typeahead-input-formatter="formatTypehead(companies, $model)"
  ng-model="model.company"
  >

Well, so far I found a possible solution through directives.

HTML

<div my-autocomplete my-autocomplete-source="element" my-autocomplete-model="obj[element.model]"></div>

DIRECTIVE

app.directive('myAutocomplete', function() {
    return {	
        restrict: 'A',
        replace: true,
        template: '<input type="text" name="{{myAutocompleteSource.model}}" placeholder="{{myAutocompleteSource.label}}" ng-model="selected" typeahead="o as o.text for o in myAutocompleteSource.options | filter:$viewValue | limitTo:5" typeahead-editable="false" />',
        scope: {
            myAutocompleteSource: '=',
            myAutocompleteModel: '='
        },
        controller: function($scope) {
            $scope.selected = null;
            $scope.$watch('selected', function() { 
                $scope.myAutocompleteModel = ($scope.selected && 'value' in $scope.selected) ? $scope.selected.value : null; 
            });
        }
    };	
});

Well... obviously this is only a trick... I would like to know if is there a cleaner, more natural way to do it... without modifying code or using directive...

for me this:

uib-typeahead="o as o.RagioneSociale for o in main.getLocation($viewValue)"

instead of:

typeahead="o as o.RagioneSociale for o in main.getLocation($viewValue)"

was really usefull

i had a json made like this:

[{"RagioneSociale":"Politi Real Estate sas","IDAnagrafica":"2516"},{"RagioneSociale":"COND METROPOLITAN","IDAnagrafica":"4325"}]


Model: {{asyncSelected | json}}
<input type="text" ng-model="asyncSelected" uib-typeahead="o as o.RagioneSociale for o in main.getLocation($viewValue)" typeahead-loading="loadingLocations" typeahead-no-results="noResults" class="form-control">

and it ended up in something like having the dropdown menu with just the RagioneSociale value and a model where i can see both the text and the id and print them with a normal {{asyncSelected}}
