Article
07/06/2017

Date de publication : novembre 2016

S’applique à : Dynamics CRM 2015

Cet exemple de code est pour Mise à jour de Microsoft Dynamics CRM 2015 et de Microsoft Dynamics CRM Online 2015.Téléchargez le package Kit de développement logiciel (SDK) de Microsoft Dynamics CRM. Il se trouve à l'emplacement suivant dans le package de téléchargement :

SampleCode\\JS\\RESTEndpoint\\JQueryRESTDataOperations

Important

Nous vous déconseillons d’utiliser jQuery dans les commandes du ruban ou les scripts de formulaire. Voir Exemple : créer, extraire, mettre à jour et supprimer le point de terminaison OData avec JavaScript pour un exemple de bibliothèque qui a les mêmes fonctionnalités sans dépendance sur jQuery.

Pour plus d'informations :Utiliser jQuery.

Notes

Si vous souhaitez simplement voir comment cet exemple fonctionne, vous pouvez installer (importer) la solution gérée JQueryRESTDataOperations_1_0_1_2_managed.zip incluse dans les fichiers de téléchargement. Cela installe la solution Opérations de données JQuery REST. Si vous installez cette solution gérée et souhaitez créer des ressources Web en utilisant les noms ci-après, votre préfixe de personnalisation de l’éditeur de solutions ne pourra pas servir d’« exemple » sauf si vous désinstallez (supprimez) la solution gérée.

Configuration requise

Cet exemple utilise les ressources web suivantes :

Notes

Le préfixe de personnalisation “sample_” n’est pas utilisé dans le code. Ces exemples fonctionnent avec le préfixe de personnalisation de n’importe quel éditeur. Toutefois, le chemin d’accès relatif du dossier Scripts simulé doit être inclus dans le nom des ressources Web.

Démontre

Cet exemple :

Effectue les opérations de création, de récupération, de mise à jour et de suppression à l’aide du point de terminaison REST avec JScript et jQuery.
Utilise jQuery, une bibliothèque populaire qui comprend des fonctionnalités pour réaliser des opérations sur les données en utilisant la méthode $.ajax.
Exécute séquentiellement les opérations sur un nouvel enregistrement de compte.

Lorsque vous exécutez l’exemple, vous avez la possibilité de supprimer l’enregistrement créé.
Présente les résultats d’une façon similaire à ce qui suit lorsque vous affichez un aperçu de la ressource Web :sample_/JQueryRESTDataOperations.htm :
1. Définition du contact principal à :<nom complet du premier enregistrement de contact de votre système>.
2. Définition du Mode de communication préféré sur Courrier électronique.
3. Définition du Revenu annuel sur Deux millions.
4. Définition du Téléphone de Mode de communication sur « Ne pas autoriser ».
5. Le compte nommé « Nom du compte de test » a été créé avec l’ID de compte : « 7780cef2-fdf4-e011-9d26-00155dba3819 ».
6. Récupération du compte avec l’ID de compte : « 7780cef2-fdf4-e011-9d26-00155dba3819 ».
7. Récupération du compte nommé « Nom du compte de test ». Ce compte a été créé le : « Mer 12 oct 11:13:56 PDT 2011 ».
8. Modification du nom du compte en « Nom du compte mis à jour ».
9. Ajout des informations concernant l’adresse.
10. Définition de l’adresse de messagerie.
11. Les modifications de l’enregistrement de compte ont été enregistrées
12. Vous avez choisi de supprimer l’enregistrement de compte.
13. Le compte a été supprimé.

Si vous choisissez de ne pas supprimer le compte, vous obtiendrez un lien pour ouvrir l’enregistrement que vous avez créé.
