javascript - Trouble accessing scope attribute in directive -


i trying access values in $scope.photores in directive of right console.log(scope.photores) in directive shows empty object. output console:

object {filename: "db372ec33603208781eb6fbf9789c816a4ab27d2.jpg", filepath: "c:\wamp\www\skittlize\photo_assets\uploads\db372ec33603208781eb6fbf9789c816a4ab27d2.jpg"} skittlesctrl.js:17 object {} skittlesctrl.js:37  'use strict';  angular.module('skittlesapp')   .controller('skittlesctrl', function ($scope, $location){     $scope.photores = {};     $scope.dropzoneconfig = {       'options': { // passed dropzone constructor         'url': 'photo_assets/save2.php'       },       'eventhandlers': {         'sending': function (file, xhr, formdata) {         },         'success': function (file, response) {           $scope.$apply(function () {             $scope.photores = json.parse(file.xhr.getresponseheader("photoinfo"));             $location.path('/uploader')             console.log($scope.photores);           });         }       }     };   })   .directive('dropzone', function () {     return function (scope, element, attrs) {       var config, dropzone;          config = scope[attrs.dropzone];          dropzone = new dropzone(element[0], config.options);          _.each(config.eventhandlers, function (handler, event) {         dropzone.on(event, handler);       });     };   })   .directive('imgswitch', ['photoserv', function (photoserv) {     function link(scope, element, attrs) {       scope.$watch('photores', function (newval) {         if (newval) {           console.log(scope.photores);           var cropper = new crop();           cropper.init('.selfie-container');           cropper.loadimg('/uploads/'+scope.photores.filename);           $('.cropbutton').on('click', function () {             photoserv.skittlize('/uploads/'+scope.photores.filename);           });         }       });     };     return {       link: link     }   }]);

is happening because change in parent scope isn't registering?

i doubt scope[attrs.dropzone] valid. don't see anywhere you're assigning scope within directive.

there 2 different ways solve this. 1 pass attribute (which may doing, don't know html looks like).

<div dropzone photores="{{photores}}"> </div>

then can call attrs.photores value.

the other option assign scope within directive. you'd use @, =, or & @ acceptable you. if remember correctly, @ takes value attribute. you'd still need pass in $scope attribute.

= on other hand bind $scope object, , create 2-way data binding. don't need here.

.directive('dropzone', function() {     return {         restrict: "a",         scope: {             photores: "@",          },         link: function(scope, element, attrs ) {             console.log(attrs.photores);             console.log(scope.photores);      }; })
