I'm using the angular ui-bootstrap typeahead and I would want to use it as a way to pick up many choices, so I'd need to get the selected value when selectMatch method is launched but I can't find how to do that in my controller
<div class='container-fluid' ng-controller="TypeaheadCtrl"> <pre>Model: {{selected| json}}</pre> <input type="text" ng-model="selected" typeahead="state for state in states | filter:$viewValue">
If I watch the selected value, I got the change every time a key is pressed...
scope.$watch('selected', function(newValue, oldValue) {... });
I got that the method selectMatch is the one which is called when the user press enter or click on the list but I don't know how to have a callback on that...
Thanks !
There is better way of doing this now. A new callback method has been added
In controller file add the following:
$scope.onSelect = function ($item, $model, $label) { $scope.$item = $item; $scope.$model = $model; $scope.$label = $label; };
In view add the following:
<input type="text" ng-model="selected" typeahead="state for state in states | filter:$viewValue" typeahead-editable="false" typeahead-on-select="onSelect($item, $model, $label)"/>
See the typeahead spec for more information (search for onSelect).

Edit: this method is not the best one now. It's better to use onSelect callback like explained in the answer above this one.
I found how how do to do what I wanted. I did see that there is a typeahead-editable attribute and if it's set to false then the selected value change only when a value from the model is selected. And so the $watch is working fine to check when a new value is selected.
<input type="text" ng-model="selected" typeahead="state for state in states | filter:$viewValue" typeahead-editable="false"> link: function(scope, elm, attrs){ scope.$watch('selected', function(newValue, oldValue) { if (newValue) console.log(oldValue+"->"+newValue); }); }
