AngularJS Keypress Keycode Directive

Question

I'm trying to write an AngularJS directive to run a function when the Escape key is pressed:

HTML

<input type="text" custom-keypress="consoleLog()">

JS

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

app.controller('appCtrl', function($scope) {
  $scope.consoleLog = function () {
    console.log('works')
  }
});

app.directive('customKeypress', function () {
    return function (scope, element, attrs) {
        element.bind("keydown keypress", function (event) {
            if(event.which === 27) {
                scope.$apply(function (){
                    scope.$eval(attrs.ngEnter);
                });

                event.preventDefault();
            }
        });
    };
});

Unfortunately when I press the Escape key nothing happens.

Here's my Plunker.

Any idea what I'm doing wrong?

Answer 1

you are targeting the wrong attribute value on your $eval call. Forked and fixed - http://plnkr.co/edit/0fsKoHAAgTvl4l2z8SfJ?p=preview

should be: scope.$eval(attrs.customKeypress);
