Angular Noob hier. Ich erstelle eine Direktive, um rekursiv einen Baum von Fragen und Unterfragen anzuzeigen. Ich benutze einen Link in der Vorlage, der eine Funktion innerhalb des Gültigkeitsbereichs aufruft. Aus irgendeinem Grund nennt es das nichteditQuestion() Methode.

Hier ist der Code und die Geigehttp://jsfiddle.net/madhums/n9KNv/

HTML:

<div ng-controller="FormCtrl">
  <questions value="survey.questions"></questions>
</div>

Javascript:

var app = angular.module('myApp', []);

function FormCtrl ($scope) {
  $scope.editQuestion = function (question) {
    alert('abc');
  };
  $scope.survey = {
    // ...
  }
}


app.directive('questions', function($compile) {
  var tpl = '<ol ui-sortable' +
    ' ng-model="value"' +
    ' class="list">' +
    '  <li ng-repeat="question in value | filter:search"' +
    '     <a href="" class="question">' +
    '       {{ question.name }}' +
    '     </a>' +
    '     <span class="muted">({{ question.type }})</span>' +
    '     <a href="" class="danger" ng-click="removeQuestion(question)">remove</a>' +
    '     <a href="" class="blue" ng-click="editQuestion(question)">edit</a>' +
    '     <choices value="question.choices"></choices>' +
    '  </li>' +
    '</ol>';

  return {
    restrict: 'E',
    terminal: true,
    scope: { value: '=' },
    template: tpl,
    link: function(scope, element, attrs) {
        $compile(element.contents())(scope.$new());
    }
  };
});

app.directive('choices', function($compile) {
  var tpl = '<ul class="abc" ng-repeat="choice in value">'+
    '  <li>' +
    '    {{ choice.name }}' +
    '    <span class="muted">' +
    '      ({{ choice.questions.length }} questions)' +
    '    </span>' +
    '' +
    '    <a href=""' +
    '      ng-click="addQuestions(choice.questions)"' +
    '      tooltip="add sub questions">' +
    '      +' +
    '    </a>' +
    '' +
    '    <questions value="choice.questions"></questions>'
    '  </li>' +
    '</ul>';

  return {
    restrict: 'E',
    terminal: true,
    scope: { value: '=' },
    template: tpl,
    link: function(scope, element, attrs) {
        $compile(element.contents())(scope.$new());
    }
  };
});

Jede Hilfe zum Verständnis wäre willkommen.
