Using Angular.js, apply the "visible" class conditionally based on a variable

My Cordova application is built with angular.js and consists of the following 2 files:

app.html

<div ng-controller="MyAppCtrl as myApp" ng-class="myApp.isWindows() ? 'windows' : ''">

and app.controller

MyAppCtrl.$inject = ['$scope'];
function MyAppCtrl($scope) {
    var vm = this;
    vm.isWindows = isWindows;    
}

function isWindows() {
    return true;
}

I need to perform a check within the isWindows function, and if the condition is met - returning true to apply the windows class in the HTML. However, this functionality is currently not working for me. I came across a tutorial that had a similar example, but it's not functioning as expected. Can anyone provide assistance?

Answer №1

The correct syntax for ng-class is important in AngularJS. To implement it correctly, make sure to use the following code snippet:

<div ng-controller="MyAppCtrl as myApp" ng-class="{windows: myApp.isWindows()}">...</div>
