Set active tab style with AngularJS

Question

I have routes set in AngularJS like this:

$routeProvider
    .when('/dashboard', {templateUrl:'partials/dashboard', controller:widgetsController})
    .when('/lab', {templateUrl:'partials/lab', controller:widgetsController})

I have some links on the topbar styled as tabs. How can I add 'active' class to a tab depending on current template or url?

Answer

A way to solve this without having to rely on URLs is to add a custom attribute to every partial during $routeProvider configuration, like this:

$routeProvider.
    when('/dashboard', {
        templateUrl: 'partials/dashboard.html',
        controller: widgetsController,
        activetab: 'dashboard'
    }).
    when('/lab', {
        templateUrl: 'partials/lab.html',
        controller: widgetsController,
        activetab: 'lab'
    });

Expose $route in your controller:

function widgetsController($scope, $route) {
    $scope.$route = $route;
}

Set the active class based on the current active tab:

<li ng-class="{active: $route.current.activetab == 'dashboard'}"></li>
<li ng-class="{active: $route.current.activetab == 'lab'}"></li>
