  • Artículo

 

Publicado: enero de 2017

Se aplica a: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online

Este ejemplo muestra cómo realizar operaciones básicas CRUD (crear, recuperar, actualizar y eliminar) y de asociación y disociación en instancias de la entidad mediante JavaScript del lado del cliente.

Nota

Este ejemplo implementa las operaciones detalladas en el Ejemplo de operaciones básicas de la API web y usa construcciones JavaScript comunes descritas en Ejemplos de la API web (JavaScript del lado del cliente).

En este tema

  • Requisitos previos

  • Ejecute este ejemplo

  • Ejemplo de código

Requisitos previos

Para ejecutar este ejemplo, se requiere lo siguiente:

  • Obtenga acceso a Dynamics 365 o la versión local 8.0 o superior.

  • Una cuenta de usuario con privilegios para importar soluciones y realizar operaciones CRUD, normalmente un rol de seguridad de administrador o personalizador del sistema.

Ejecute este ejemplo

Para ejecutar este ejemplo, descargue el paquete de solución aquí Microsoft CRM Web API Basic Operations Sample (Client-side JavaScript). Descargue el archivo Microsoft CRM Web API Basic Operations Sample (Client-side JavaScript).zip y extraiga el contenido. Busque la solución WebAPIBasicOperations_1_0_0_1_managed.zip y impórtela en la organización de Dynamics 365 y ejecute el ejemplo. Para obtener instrucciones sobre cómo importar la solución de ejemplo, veaEjemplos de la API web (JavaScript del lado del cliente).

    <p>This page demonstrates the CRM Web API's basic operations using JavaScript.</p>

    <h2>Instructions</h2>
    <p>
        Choose your preferences and run the JavaScript code. 
    Use your browser's developer tools to view the output written to the console (e.g.: in IE11 or Edge, 
    press F12 to load the Developer Tools).
    </p>
    <p>
        Remove sample data (Choose whether you want to delete sample data created during this execution):
            <br />
        <input name="removesampledata" type="radio" value="yes" checked />
        Yes
            <input name="removesampledata" type="radio" value="no" />
