Updating the model property has no effect on the view when updating the model in event callback, any ideas to fix this?
This is my service:
angular.service('Channel', function() {
var channel = null;
return {
init: function(channelId, clientId) {
var that = this;
channel = new goog.appengine.Channel(channelId);
var socket = channel.open();
socket.onmessage = function(msg) {
var args = eval(msg.data);
that.publish(args[0], args[1]);
};
}
};
});
publish() function was added dynamically in the controller.
Controller:
App.Controllers.ParticipantsController = function($xhr, $channel) {
var self = this;
self.participants = [];
// here publish function is added to service
mediator.installTo($channel);
// subscribe was also added with publish
$channel.subscribe('+p', function(name) {
self.add(name);
});
self.add = function(name) {
self.participants.push({ name: name });
}
};
App.Controllers.ParticipantsController.$inject = ['$xhr', 'Channel'];
View:
<div ng:controller="App.Controllers.ParticipantsController">
<ul>
<li ng:repeat="participant in participants"><label ng:bind="participant.name"></label></li>
</ul>
<button ng:click="add('test')">add</button>
</div>
So the problem is that clicking the button updates the view properly, but when I get the message from the Channel nothings happens, even the add() function is called
You are missing $scope.$apply().
Whenever you touch anything from outside of the Angular world, you need to call $apply, to notify Angular. That might be from:
In your case, do something like this:
// inject $rootScope and do $apply on it
angular.service('Channel', function($rootScope) {
// ...
return {
init: function(channelId, clientId) {
// ...
socket.onmessage = function(msg) {
$rootScope.$apply(function() {
that.publish(args[0], args[1]);
});
};
}
};
});
