Troubleshooting a perplexing problem with an unresponsive AngularJS directive

Here is the code from my app.js file (main JavaScript file)

var currentUserId;
window.myApp = angular.module('myApp', ['ajoslin.mobile-navigate', 'ngMobile',
    'myApp.Registermdl',
    'ngProgress', 'myApp.login', 'ngCookies', 'myApp.CreateUsermdl', 'myApp.viewMap', 'myApp.createMap', 'ui.bootstrap',
'myApp.logout', 'myApp.viewCollege']);

myApp.config(['$routeProvider', function ($routeProvider) {
    $routeProvider.when('/login', { templateUrl: 'app/Login/login.html', controller: 'LoginCtrl' });
    $routeProvider.when('/home', { templateUrl: 'app/Home/home.htm', controller: 'HomeCtrl' });
    $routeProvider.when('/createuser', { templateUrl: 'app/CreateUser/createUser.html', controller: 'CreateUserCtrl' });
    $routeProvider.when('/signup', { templateUrl: 'app/Register/register.html', controller: 'RegisterCtrl' });
    $routeProvider.when('/logout', { templateUrl: 'app/Login/login.html', controller: 'LogoutCtrl' });
    $routeProvider.when('/view-map', { templateUrl: 'app/ViewMap/viewmap.html', controller: 'ViewMapCtrl' });
    $routeProvider.when('/create-map', { templateUrl: 'app/CreateMapAddress/create-mapaddress.html', controller: 'CreateMapAddressCtrl' });
    $routeProvider.when('/view-college', { templateUrl: 'app/ViewColleges/viewcolleges.html', controller: 'ViewCollegeCtrl' });
    $routeProvider.otherwise({ redirectTo: '/login' });
}]).directive("collegeAppMain", function ($location) {
    return {
        restrict: "A",
        link: function (scope) {
            scope.getClass = function (path) {
                if ($location.path() == path) {
                    return "active"
                } else {
                    return ""
                }
            }
        }
    };
});

This is the directive code I have implemented

directive("collegeAppMain", function ($location) {
        return {
            restrict: "A",
            link: function (scope) {
                scope.getClass = function (path) {
                    if ($location.path() == path) {
                        return "active"
                    } else {
                        return ""
                    }
                }
            }
        };
    });

I included the collegeAppMain directive in my main HTML index page

<body>
    <nav class="navbar navbar-default nav-custom" **collegeAppMain** role="navigation"></nav>
.
.
.
.
.</body>

However, it seems to not be functioning correctly. Interestingly, when I change the directive name from collegeAppMain to "dfhsfksksdf", it works as expected.

I want to use the collegeAppMain name for my directive and I am unsure why it's causing issues. Can you offer any insight into this problem?

Why does the directive work when named 'dfhsfksksdf' but not when named 'collegeAppMain'?

Answer №1

When creating a directive using camelCase, remember to reference it in HTML like this: camel-case.

In your scenario, the HTML should appear as follows:

<nav college-app-main class="navbar navbar-default nav-custom"  role="navigation></nav>

Another aspect to keep in mind is code formatting. $routeProvider utilizes 'method chaining', allowing you to structure your code like so:

myApp.config(['$routeProvider', function ($routeProvider) {
   $routeProvider
     .when('/login', { 
         templateUrl: 'app/Login/login.html', 
         controller: 'LoginCtrl' })
      .when('/home', { 
         templateUrl: 'app/Home/home.htm', 
         controller: 'HomeCtrl' })
      .otherwise({
         templateUrl: 'some.html', 
         controller: 'Home2Ctrl'
      })
});

This format is much more visually appealing.
