I am creating a demo application with two controllers communicating through a service containing some data. It is a kind of contacts book. A user can edit selected person from the list.
The data is stored in array of objects and I use a custom directive to perform some manipulations with that objects' text properties.
The problem is that a text rendered in the list using the custom directive is not updated on model change (when typing something in name fields) while a text that is placed using {{}} changes while typing.
Here is a sample showing a problem:
js
var contacts = angular.module('contacts', []);
contacts.service('database', ['$rootScope', function ($rootScope) {
return {
db : [
{person:{fName:John, lName:Williams}, phone:11111111111},
{person: {fName:Sara, lName:Lewis}, phone:222222222},
{person: {fName:Lana, lName:Watson}, phone:33333333333},
{person: {fName:John, lName:Smith}, phone:4444444444}
],
selectedPerson : null,
setSelected : function (i) {
this.selectedPerson = i;
$rootScope.$broadcast('selected');
}
}
}]);
contacts.controller(listCtrl, function($scope, database) {
$scope.list = database.db;
$scope.getSelected = function() {
return database.selectedPerson;
};
$scope.setSelected = function(i) {
database.setSelected(i);
};
});
contacts.controller(editorCtrl, function($scope, database) {
$scope.editing = database.selectedPerson;
$scope.$on('selected', function(event) {
$scope.editing = database.selectedPerson;
});
});
contacts.directive('personName', function() {
return {
restrict: 'AEC',
scope:{
personName: '='
},
link: function(scope, elem, attrs) {
scope.$watch(function(){return scope.personName;}, function(obj) {
var fullName = obj.fName + + obj.lName;
elem.text(fullName);
});
}
};
});
html
<div ng-app=contacts>
<div class='list' ng-controller=listCtrl>
<div ng-repeat=i in list
ng-click=$parent.setSelected(i)
ng-class={'sel': ($parent.getSelected() === i)}>
<span person-name=i.person></span>, {{i.phone}}
</div>
</div>
<div class='edit' ng-controller=editorCtrl>
First name: <input type=text ng-model='editing.person.fName'> <br>
Last name: <input type=text ng-model='editing.person.lName'> <br>
Phone: <input type=text ng-model='editing.phone'> <br>
</div>
</div>

Maybe the problem is with $watch, but everything seems to be ok. Any suggestions?
P.S. In real app I need to use the directive to do more complex text manipulation than just concatenation.
