javascript - Unable to access AngularJS attribute in directive -

i'm trying implement simple directive in angularjs. in end, want able use directive this:

<share-buttons url="google.com"></share-buttons> 

my directive looks (coffee script):

module.directive 'sharebuttons', () ->       controller = ['$scope', ($scope) ->          $scope.share = () ->             console.log $scope.url      ]      return {         restrict: 'ea'         scope: {             url: '=url'         }         templateurl: viewpath_common('/directives/share-buttons')         controller: controller     } 

and here's template (jade):

.social-icons     button.btn.btn-li(ng-click="share()")         i.fa.fa-linkedin.fa-fw 

when click button, correct function called ($scope.share), thing logged undefined.

can me?

its because url attribute 2 way data bound "="

so it's looking scope variable this:

$scope.google.com =  // should value. 

to passed controller directive.

if want string passed, use "@" 1 way binding

scope: {         url: '@' } 

note: can access via attributes in link function of directive (which don't have above)

// restrict: 'ea' scope: {     url: '@' } templateurl: "someurl", link: function(scope, elem, attrs) {     console.log(attrs.url); }
