Ejemplo de funciones y acciones de la API web (JavaScript del lado del cliente)
Este ejemplo demuestra cómo realizar funciones y acciones enlazadas y sin enlazar, incluidas acciones personalizadas, mediante la API web de Microsoft Dataverse utilizando JavaScript del lado del cliente.
Nota
Este ejemplo implementa las operaciones detalladas en el Ejemplo de funciones y acciones de la API web y utiliza las construcciones comunes de JavaScript del lado cliente que se describen en Ejemplos de API web (JavaScript del lado cliente)
En esta sección
Requisitos previos
Para ejecutar este ejemplo, se requiere lo siguiente:
- Acceder a un entorno de Dataverse.
