    • Learn how alert messages help you communicate feedback and status updates using both default and scripted approaches.

    Alerts are components that display standardized notifications, such as feedback, warnings, and confirmations. They’re easy to configure without scripting, but you can add a script for more advanced functionality.

    Figure 1. Alert message types
    A series of different types of alerts.

    UI Builder supports several types of alert messages. To see how each one behaves, open the Alert component documentation and try out different settings in the interactive preview.

    Customize alert messages with a client script in UI Builder

    Use a client script to create dynamic, context-sensitive alert messages.

    Role required: admin

    Pourquoi et quand exécuter cette tâche

    Scripted alerts provide notifications that respond to events or external data. They are highly flexible and can react to complex conditions, but require scripting knowledge and more effort to maintain. In this example, a button triggers a client script that generates multiple alerts with custom messages.
