Access controller scope from directive of nested directive

angularjs

Solution

Use the '&' syntax to allow your isolated scope to call a method defined on the parent scope. Also, you don't need any transclusion for these directives.

HTML:

<choice-tree ng-model="myTree" my-alert="myAlert()"></choice-tree>

Directives:

app.directive('choiceTree', function () {
    return {
        template: '<ul><choice ng-repeat="choice in tree"></choice></ul>',
        replace: true,
        //transclude: true,
        restrict: 'E',
        scope: {
            tree: '=ngModel',
            myAlert: '&'
        },
    };
});

app.directive('choice', function ($compile) {
    return {
        restrict: 'E',
        //transclude: true,
        template: '<li>' +
            '<span ng-click="myAlert()">' +
            '<input type="checkbox" ng-checked="choice.checked"> {{choice.name}} - {{name}}' +
            '</span>' +
            '</li>',
        link: function (scope, elm, attrs) {
            //Add children by $compiling and doing a new choice directive
            if (scope.choice.children.length > 0) {
                var childChoice = $compile('<choice-tree ng-model="choice.children" my-alert="myAlert()"></choice-tree>')(scope)
                elm.append(childChoice);
            }
        }
    };
});

Fiddle.

Problem

please see my fiddle and help me find a way to access function myAlert from nested directive "choice". A found some solutions where was shared some properties of scope like this: http://jsfiddle.net/zbD95/6/ but I need use functions and properties from scope together. Thanks!!! Here is duplicate of my fiddle: HTML part of fiddle: ``` <!doctype html> <html ng-app="plunker" > <head> <meta charset="utf-8"> <title>AngularJS Plunker</title> <link rel="stylesheet" href="style.css"> </head> <body ng-controller="MainCtrl"> <choice-tree ng-model="myTree"></choice-tree> <hr /> <!--$scope.myTree = {{myTree | json}}--> </body> </html> ``` JS part of fiddle: ``` var app = angular.module('plunker', []); function Choice(name, children) { this.name = name; this.checked = false; this.children = children || []; } var apparel = new Choice('Apparel', [ new Choice('Mens Shirts', [ new Choice('Mens Special Shirts'), ]), new Choice('Womens Shirts'), new Choice('Pants') ]); var boats = new Choice('Boats'); app.controller('MainCtrl', function($scope) { $scope.name = 'World'; $scope.myTree = [apparel, boats]; $scope.myAlert = function(ev){ alert('ad'); }; }); app.directive('choiceTree', function() { return { template: '<ul><choice ng-repeat="choice in tree"></choice></ul>', replace: true, transclude: true, restrict: 'E', scope: { tree: '=ngModel' } }; }); app.directive('choice', function($compile) { return { restrict: 'E', transclude: true, //In the template, we do the thing with the span so you can click the //text or the checkbox itself to toggle the check template: '<li>' + '<span ng-click="myAlert(choice)">' + '<input type="checkbox" ng-checked="choice.checked"> {{choice.name}} - {{name}}' + '</span>' + '</li>', link: function (scope, elm, attrs) { //Add children by $compiling and doing a new choice directive if (scope.choice.children.length > 0) { var childChoice = $compile('<choice-tree ng-model="choice.children"></choice-tree>')(scope) elm.append(childChoice); } } }; }); ```
