Can directives reference service information?

Question

I have the following service:

 myapp.service('myService', function () {

      var familyList = this;
      familyList.people = [
        { name: 'Jax', dob: '01/01/1974', cell: '3035551212', carrier: 'ATT', email: 'jax@soa.com', active: true },
        { name: 'Tara', dob: '03/01/1974', cell: '3035551313', carrier: 'SPRINT', email: 'tara@soa.com', active: false }];

 });

I have the following directive:

  myapp.directive('applyplugin', function () {
      return {
          link: function ($scope, myService) {
              $scope.myService = myService;
              alert(myService.people.length);
              $("select[id^='ms']").each(function () {
                  $(option).remove();
              });
          }
      }
  });

Can I reference the familyList array from the directive?

Sure, but the service (dependencies) injection does not take place in the link function, but in the one definig the directive.

The code becomes:

myapp.directive('applyplugin', function (myService) {
    return {
        link: function ($scope) {
            $scope.myService = myService;
            alert(myService.people.length);
            $("select[id^='ms']").each(function () {
                $(option).remove();
            });
        }
    }
});

You cannot inject anything in the link function, its signature is fixed and is link(scope, element, attributes, ...requiredDirectives) {... } (you won't use the last parameter most of the times, it is for when you directive requires the use of another using ^someDir syntax)

NOTE: You probably want to use this element parameter in your link function to only affect elements that are within the directive: element.find("select[id^='ms']").each( ... )

thanks for this answer. Could you take a look at my other question to see if you can answer it? http://stackoverflow.com/questions/29382602/reloading-my-drop-down-when-using-a-custom-directive — webdad3, Apr 03 '15 at 20:53
