Answer 1

This is another list of values angularjs directive that is using twitter's typeahead: https://github.com/mihaigiurgeanu/lov-typeahead. You can use it with bootstrap, but also without bootstrap.

If you are using bower, you can install it doing:

bower install lov-typeahead --save

Just wanted to add on to the answer provided by @pkozlowski.opensource - the behavior displayed in jsfiddle.net/jLupa no longer works with version 0.10.0 of the Angular's UI-Bootstrap. See here: jsfiddle.net/jLupa/87/ . The only change I made was updating to version 0.10.0, and you can see that both input boxes resolve to the postal code.

I has a similar problem,

<input type="text" ng-model="select" typeahead="a as a.Value for a in countries | filter:{{ Value:$viewValue }} "class="form-control" typeahead-editable="false" >

{ Code: AL,ParentCode: null,Value: Albania,Id: 1206,Name: countries }

but dindt work, with the use of a service in this way

$scope.countries = []; _services.getcountries(function(result) { $scope.countries = result; });

and was solved with

$scope.countries = []; _services.getcountries(function(result) { $.each(result, function(i, o) { $scope.countries.push(o); }); });

I hope help somebody

try the following before saving / validating 

modelCtrl.$setValidity('editable', true);

The typeahead directive from http://angular-ui.github.io/bootstrap/ is very, very flexible and there are many ways of achieving the desired functionality. I'm presenting 2 of them here.

Firstly, the typeahead directive uses syntax very similar to the AngularJS select directive. This gives you full control over a displayed label and the data bound as model value. So what you could do is to simply display address as a label and bind postcode to the selPcode directly:

<input type="text" ng-model="selPcode" typeahead="state.postcode as state.address for state in states | filter:$viewValue" typeahead-editable="false" />

The key here is the as part is in the typeahead expression: typeahead="state.postcode as state.address for state in states

Also, please note that I'm using the typeahead-editable="false" attribute to bind model only when a selection is made. A working jsFiddle here: http://jsfiddle.net/jLupa/

Another solution, if you really need to use a callback function is to use the typeahead-on-select attribute:

<input type="text"  typeahead-on-select="setPcode($item)" ng-model="selected" typeahead="state.address for state in states | filter:$viewValue" />

It allows you to specify a callback when a match is selected. A working fiddle here: http://jsfiddle.net/t8BV2/

As the last note: ng-change won't work here since it would react on any change in the input while you want to capture selection only. ng-click is not of much use either as it reacts on clicking on the input field and not the matches popup. On top of this it wouldn't react on selections made by using keayboard.

@pkozlowski-opensource 's great solution has one drawback: you can't initialise the typeahead from the ng-model property in this way, at least if you want it to display the item's description and not its code.

I found a way to solve this by configuring the typeahead like this:

<input type="text" ng-model="selected" typeahead="state as state.address for state in states | filter:$viewValue" />

This returns a state object to the model property which can be initialised by setting the value to the appropriate object:

    $scope.selected = {postcode:'M1',address:'Manchester'};

Working fiddle here: https://jsfiddle.net/0y3ntj4x/3/

I think this scenario is missing from the angular-bootstrap documentation for the typeahead.
