ng-class not acting as the main class, as initially anticipated

I have a set of icons that can be either "active" or "inactive" based on boolean values in the $scope. To visually differentiate between them, I've created two CSS classes called activeIcon and inactiveIcon that simply change the color. Currently, all icons are assigned the inactiveIcon class using class="", and I am attempting to dynamically switch to the activeIcon class using ng-class="" if the boolean condition is met.

After conducting some research, I believe this approach should work as intended. Here is a link to a demonstration.

CSS FILE:

.activeIcon { color: #333333; }
.inactiveIcon { color: #DDDDDD; }

JS FILE:

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

app.controller('MainCtrl', function($scope) {
  $scope.attachments = 1;
});

HTML:

<body ng-controller="MainCtrl">
    <span class="inactiveIcon" 
          tooltip="Attachments" 
          ng-class="{ 'activeIcon' : app.attachments }">
          TEST
    </span>
  </body>

Answer №1

Initially, the

ng-class="{ 'clrOn' : app.attachments }"
directive is not recognizing the attachments variable as it's defined directly on scope and not on scope.app. Therefore, it should be modified to
ng-class="{ 'clrOn' : attachments }"
.

Furthermore, the ng-class directive does not replace any existing class attributes, but simply adds to them. Consequently, your span element will retain both classes unless you specify otherwise using ng-class.
