Can I listen on a change in service?

[Yonatan Kra]

Hi,

I have a service that keeps my data across views (a simple json).

Is there a way for me to watch on changes for this service from a directive?

You could bind to the service from your directive. 

mod.directive('myDirective', ['myService', function (myService) {

  return {

    restrict: 'A',

    ...

  };

});

This is usually not necessary, though, and probably means that the directive is doing too much if it's absolutely necessary.

ng-model could, for instance, depend on a Models service to pull its object, but it uses attributes instead. Generally, that's the right way to go.

Hi. Thanks. I'm an almost total newbie... could you explain please (or refer me to an example) how to use ng-model? I tried to use it in mt partial but it kept ignoring the service value.

<script>function MyCtrl($scope, myService) { $scope.service = myService; }</script>

<div ng-controller="MyCtrl">

   <input ng-model="service.value" />

</div>

If this doesn't help, please link to a plunkr that isn't working but you think should be, and we might be able to fix it for you.
