angular ui-bootstrap typeahead callback on selectM

Question

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 !

Answer 1

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).

try the following before validation

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

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);
     });
}

Following should be your HTML

 <input id="title" type="text"  ng-model="title"  typeahead="data.enquiry_title for data in titleData | filter:$viewValue | limitTo:8" 
typeahead-on-select='onSelect($item, $model, $label)' />

just add typeahead-on-select in input tag with the callback function.

Following would go inside controller

$scope.onSelect = function ($item, $model, $label) {
            console.log($item);
            if($item.tid)
                $scope.activeTitleId = $item.tid
        };

inside $item you'll get the whole object which you have passed in the main array of suggestion list
