# Servicios

## JavaScript

Se puede acceder al entorno de ejecución de JavaScript con el servicio de JavaScript. Permite ejecutar JavaScript en el cliente y, opcionalmente, devolver una respuesta.

```powershell
function OnClick {
    #Don't return a value    
    $JavaScript.InvokeVoid("alert('Hello!')")
    
    #Return a value
    $Value = $JavaScript.Invoke("'String'")
    $Message.Success($Value)
}
```

## Mensajes

El servicio de mensajes se utiliza para mostrar mensajes al usuario final. Se basa en `IMessageService`. Puede encontrar más información [aquí](https://antblazor.com/en-US/components/message#API).

```powershell
function OnClick {
   $Message.Success("Hello!")
}
```

## Notificaciones

El servicio de notificaciones se utiliza para mostrar mensajes que incluyen más información que el servicio de mensajes. Puede personalizar el título, el mensaje y el icono. Puede encontrar más información [aquí](https://antblazor.com/en-US/components/notification).

```powershell
function OnClick {
    $Config = [AntDesign.NotificationConfig]::new()
    $Config.Message = "Title" 
    $Config.Description = "This is the body of the notification"
    $Notification.Open($Config)
}
```

## Navegación

El servicio de navegación se puede utilizar para desplazarse entre páginas del portal, páginas de administración y páginas externas. El servicio de navegación es una instancia de [NavigationManager](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.components.navigationmanager?view=aspnetcore-8.0).

```powershell
function OnClick {
    $Navigation.NavigateTo("/portal/page/name")
}
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/powershell-universal/es/portal/portal-widgets/services.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
