The functionality of scope.$apply in Angular Js appears to be ineffective

I recently started learning angular js and decided to test an example from . However, I am experiencing some difficulty as it does not seem to be functioning correctly.

Below is the HTML code I am using:

<!DOCTYPE html>
 <html lang="en">
    <head>
    <meta charset="utf-8" />
    <title></title>
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
    <script src="js/twitterApp.js"></script>
</head>
<body>
    <div ng-app="twitterApp">
        <div app-controller="AppCtrl">
            <div enter="loadMoreTweets()">Roll over to load tweets.</div>
        </div>
    </div>
</body>
</html>

Here are the specified app, controller, and directive:

var tApp= angular.module("twitterApp",[])

tApp.controller("AppCtrl", function ($scope) {
   $scope.loadMoreTweets = function () {
      alert('Loading tweets.');
   }
})

 tApp.directive("enter", function () {
     return function (scope, element, attrs) {
        element.bind("mouseenter", function () {
            scope.$apply(attrs.enter);    
        })
     }
 })

The issue lies with the following statement which seems to be failing, although I have followed the demo instructions accurately:

scope.$apply(attrs.enter)

Even after attempting the alternative method mentioned below, the error console still indicates that "loadMoreTweets" is not found. Any assistance on this matter would be greatly appreciated.

scope.loadMoreTweets()

Answer №1

<div app-controller="AppCtrl">
