Sample: Create, retrieve, update, and delete using the OData endpoint with JavaScript and jQuery

  • Artículo

 

Applies To: Dynamics CRM 2013

This sample code is for Microsoft Dynamics CRM 2013 and Microsoft Dynamics CRM Online. Download the Microsoft Dynamics CRM SDK package. It can be found in the following location in the download package:

SampleCode\JS\RESTEndpoint\JQueryRESTDataOperations

Important

We don’t recommend using jQuery in form scripts or ribbon commands. See Sample: Create, retrieve, update, and delete using the OData endpoint with JavaScript for a sample library that has the same capabilities without a dependency on jQuery.

More information:  Use of jQuery.

Note

If you just want to see how this sample works you can install (import) the JQueryRESTDataOperations_1_0_1_2_managed.zip managed solution included in the download files. This installs the JQuery REST Data Operations solution. If you install this managed solution and want to create the web resources using the names below, your solution publisher customization prefix can’t be “sample” unless you uninstall (delete) the managed solution.

Requirements

This sample uses the following web resources:

  • sample_/JQueryRESTDataOperations.htm
    Use this HTML page to start the sample and view the progress of the actions. This page is the configuration page for the JQuery REST Data Operations solution.

  • sample_/Scripts/jquery1.9.1.min.js
    The minimized version of jQuery included with Microsoft Visual Studio 2010 web application projects. The content of this library is not included here.

  • sample_/Scripts/JQueryRESTDataOperationsSample.js
    A JScript web resource that performs the operations. This library depends on the SDK.JQuery.js library.

  • sample_/Scripts/SDK.JQuery.js
    A JScript web resource that contains a reusable library to perform actions with the REST endpoint using JQuery.

    Note

    A similar library without the dependency on JQuery is available in the Sample: Create, retrieve, update, and delete using the OData endpoint with JavaScript.

Note

The customization prefix “sample_” is not used in code. These samples will work using the customization prefix from any publisher. However, the relative path of the simulated Scripts folder must be included in the name of the web resources.

Demonstrates

This sample:

  • Performs create, retrieve, update and delete operations using the REST endpoint with JScript and jQuery.

  • Uses jQuery, a popular library that includes capabilities to perform data operations using the $.ajax method.

  • Sequentially executes the operations on a new account record.

    When you run the sample you will have the choice to delete the record created.

  • Displays results similar to the following when you preview the web resource: sample_/JQueryRESTDataOperations.htm

    1. Setting the primary contact to: <the full name of the first Contact record in your system>.

    2. Setting Preferred Contact Method to Email.

    3. Setting Annual Revenue to Two Million.

    4. Setting Contact Method Phone to "Do Not Allow".

    5. The account named "Test Account Name" was created with the AccountId: "7780cef2-fdf4-e011-9d26-00155dba3819".

    6. Retrieving account with the AccountId: "7780cef2-fdf4-e011-9d26-00155dba3819".

    7. Retrieved the account named "Test Account Name". This account was created on: "Wed Oct 12 11:13:56 PDT 2011".

    8. Changing the account Name to "Updated Account Name".

    9. Adding Address information.

    10. Setting Email address.

    11. The account record changes were saved

    12. You chose to delete the account record.

    13. The account was deleted.

If you choose not to delete the account you’ll see a link to open the record you created.

sample_/Scripts/SDK.JQuery.js

This library contains public methods for the following operations:

  • createRecord

  • retrieveRecord

  • updateRecord

  • deleteRecord

  • retrieveMultipleRecords

Each of these methods includes a successCallback and errorCallback parameter. These parameters accept a reference to a function that is called when the data operation succeeds or fails.
