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\\JavaScriptRESTDataOperations

Si vous souhaitez simplement voir comment cet exemple fonctionne, vous pouvez installer (importer) la solution gérée JavaScriptRESTDataOperations_1_0_0_1_managed.zip incluse dans les fichiers de téléchargement. Après avoir installé cette solution gérée, consultez la page de configuration de la solution pour visualiser les actions exécutées.

Si vous installez cette solution gérée et que vous souhaitez créer des ressources Web en utilisant les noms de cette rubrique, votre préfixe de personnalisation de l’éditeur de solutions ne peut pas être « sample », sauf si vous désinstallez (supprimez) la solution gérée.

Configuration requise

Cet exemple utilise les ressources web suivantes :

sample_/JavaScriptRESTDataOperationsSample.htm
Une page HTML qui contient les éléments d'interface utilisateur de cet exemple.
sample_/Scripts/JavaScriptRESTDataOperationsSample
Une bibliothèque qui contient les fonctionnalités pour gérer les éléments d’interface utilisateur sur la page et inclut les actions exécutées par l’exemple.
sample_/Scripts/SDK.REST.js
Une bibliothèque réutilisable et générique qui simplifie les opérations sur les données asynchrones en utilisant le point de terminaison Rest des ressources Web.

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.

Cette bibliothèque contient les méthodes publiques pour les opérations suivantes :

SDK.REST.createRecord
SDK.REST.retrieveRecord
SDK.REST.updateRecord
SDK.REST.deleteRecord
SDK.REST.retrieveMultipleRecords
SDK.REST.associateRecords
SDK.REST.disassociateRecords

Chacune de ces méthodes inclut un paramètre successCallback et errorCallback. Ces paramètres acceptent une référence à une fonctionnalité appelée lorsque l’opération sur les données aboutit ou échoue.
