ngMessageExp
is a directive with the purpose to show and hide a particular message. For ngMessageExp
to operate, a parent ngMessages
directive on a parent DOM element must be situated since it determines which messages are visible based on the state of the provided key/value map that ngMessages
listens on.
<!-- using attribute directives --> <ANY ng-messages="expression"> <ANY ng-message-exp="expressionValue">...</ANY> </ANY> <!-- or by using element directives --> <ng-messages for="expression"> <ng-message when-exp="expressionValue">...</ng-message> </ng-messages>
