# Servicios

Acceda a los servicios de JavaScript, mensajes, notificaciones y navegación en los widgets del portal de PowerShell Universal para crear interfaces de usuario interactivas.

## 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. Está basado en `IMessageService`.

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

## Notificaciones

El servicio de notificaciones muestra notificaciones que incluyen más información que el servicio de mensajes. Puede personalizar el título, el mensaje y el icono.

```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")
}
```

## 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.
