[javascript] Angularjs if-then-else construction in expression

Can I somehow use if-then-else construction (ternary-operator) in angularjs expression, for example I have function $scope.isExists(item) that has to return bool value. I want something like this,

<div ng-repeater="item in items">
    <div>{{item.description}}</div>
    <div>{{isExists(item) ? 'available' : 'oh no, you don't have it'}}</div>
</div>

I know that I can use function that returns string, I'm interesting in possibility of using if-then-else construction into expression. Thanks.

This can be done in one line.

{{corretor.isAdministrador && 'YES' || 'NÂO'}}

Usage in a td tag:

<td class="text-center">{{corretor.isAdministrador && 'Sim' || 'Não'}}</td>

I am trying to check if a key exist in an array in angular way and landed here on this question. In my Angularjs 1.4 ternary operator worked like below

{{ CONDITION ? TRUE : FALSE }}

hence for the array key exist i did a simple JS check

Solution 1 : {{ array['key'] !== undefined ? array['key'] : 'n/a' }}

Solution 2 : {{ "key" in array ? array['key'] : 'n/a' }}

You can easily use ng-show such as :

    <div ng-repeater="item in items">
        <div>{{item.description}}</div>
        <div ng-show="isExists(item)">available</div>
        <div ng-show="!isExists(item)">oh no, you don't have it</div>
    </div>

For more complex tests, you can use ng-switch statements :

    <div ng-repeater="item in items">
        <div>{{item.description}}</div>
        <div ng-switch on="isExists(item)">
            <span ng-switch-when="true">Available</span>
            <span ng-switch-default>oh no, you don't have it</span>
        </div>
    </div>

You can use ternary operator since version 1.1.5 and above like demonstrated in this little plunker (example in 1.1.5):

For history reasons (maybe plnkr.co get down for some reason in the future) here is the main code of my example:

{{true?true:false}}
