Problem with applying ng-class directive in AngularJS

I am currently developing an application using AngularJs and Bootstrap. My goal is to display the title of a 'scenario' with different styling based on its status, along with a specific icon.

Initially, I attempted the following approach:

<span class="text-success" data-ng-if="scenario.status=='success'"><i class="fa fa-check-circle"></i>Scenario {{scenario.title}}</span>
<span class="text-danger" data-ng-if="scenario.status=='fail'"><i class="fa fa-exclamation-circle"></i>Scenario {{scenario.title}}</span>
<span data-ng-if="scenario.status=='none'">Scenario {{scenario.title}}</span>

This method has been effective so far. However, I would like to enhance it by utilizing ng-class to avoid code duplication. I have made the following modifications:

 <span ng-class="{text-success:scenario.status=='success' || text-danger:scenario.status=='fail'}">Scenario {{scenario.title}}
                        <i ng-class="{fa fa-check-circle:scenario.status=='success' || fa fa-exclamation-circle:scenario.status=='fail'}"></i>
                        </span>

Unfortunately, this new approach does not seem to work as expected, and I am having trouble identifying the issue. Any assistance would be greatly appreciated.

Thank you!

Answer №1

Here is the accurate resolution:

<span ng-class="{'text-success': scenario.status === 'success', 'text-danger': scenario.status === 'fail'}">
    Scenario {{scenario.title}}
    <i class="fa" ng-class="{'fa-check-circle': scenario.status === 'success', 'fa-exclamation-circle': scenario.status === 'fail'}"></i>
</span>

The ngClass directive empowers you to dynamically assign CSS classes to an HTML element by binding an expression that represents all the classes to be included.

Answer №2

$scope.setClassName = function() {
     return "style-" + situation.condition;      
}

Next, apply:

ng-style="setClassName()"
