Navigating within an ng-if or ng-show in AngularJS

Currently, I am developing a web application using AngularJS and there are times when I need to verify if the element inside the ng-if or ng-show directive belongs to a specific list. The approach I am using right now is shown below:

<div ng-if="object.element=='A' || object.element=='B' || object.element=='C'">
    <p>Hello World!</p>
</div>

However, I am curious to know if there is a more concise way to achieve the same result like this:

<div ng-if="object.element in ['A','B','C']">
    <p>Hello World!</p>
</div>

Answer №1

If you want to achieve this, you can try the following:

<div ng-if="['X','Y','Z'].indexOf(object.element)>-1">
    <p>Greetings Earthlings!</p>
</div>

Alternatively, you can also use this code snippet:

<div ng-if="['X','Y','Z'].indexOf(object.element)+1">
    <p>Greetings Earthlings!</p>
</div>

Answer №2

Give this a try

HTML

<div ng-show="toggleContent()">
    <p>Hey there!</p>
</div>

JS

    $scope.data = {
        item: 'X'
    };

   $scope.toggleContent = function () {
        return $scope.data.item == 'X' || $scope.data.item == 'Y' || $scope.data.item == 'Z'
    }
