發行項
07/06/2017

發行︰ 2016年11月

適用於： Dynamics CRM 2015

這個範例程式碼適用於 Microsoft Dynamics CRM 2015 和 Microsoft Dynamics CRM Online 2015 更新。下載 Microsoft Dynamics CRM SDK 套件。可以在下列位置的下載套件中找到：

SampleCode\JS\RESTEndpoint\JQueryRESTDataOperations

重要

不建議在表單指令碼或功能區命令中使用 jQuery。針對擁有相同的功能，但沒有 jQuery 相依性的範例程式庫，請參閱範例：使用 OData 端點和 JavaScript 建立、擷取、更新及刪除。

其他資訊：使用 jQuery。

注意

如果只是想要了解此範例運作方式，可以安裝 (匯入) JQueryRESTDataOperations_1_0_1_2_managed.zip 受管理解決方案 (包含在下載檔案中)。這會安裝 JQuery REST 資料作業解決方案。如果您安裝此受管理的解決方案且要使用下列名稱建立 Web 資源，您的解決方案發行者自訂的首碼不可以是「sample」，除非您解除安裝 (刪除) 受管理的解決方案。

需求

此範例使用下列 Web 資源：

sample_/JQueryRESTDataOperations.htm
使用此 HTML 頁面啟動範例和檢視動作的進度。此頁面為 JQuery REST 資料作業解決方案的組態頁面。
sample_/Scripts/jquery1.9.1.min.js
包括在 Microsoft Visual Studio Web 應用程式專案中最精簡的 jQuery 版本。此程式庫內容未包含於此處。
sample_/Scripts/JQueryRESTDataOperationsSample.js
執行作業的 JScript Web 資源。此程式庫依賴 SDK.JQuery.js 程式庫。
sample_/Scripts/SDK.JQuery.js
JScript Web 資源，包含可重複使用的程式庫，使用 REST 端點與 JQuery 執行動作。

注意

沒有 JQuery 相依性、類似程式庫可在範例：使用 OData 端點和 JavaScript 建立、擷取、更新及刪除中找到。

注意

自訂首碼 “sample_” 並未用於程式碼。利用任何發行者的自訂首碼，這些範例都會運作。不過已模擬 Scripts 資料夾的相對路徑必須包含在 Web 資源的名稱中。

示範

此範例：

使用 REST 端點和 JScript 及 jQuery，執行建立、擷取、更新及刪除作業。
使用 jQuery，這個常用的程式庫包括功能，可使用 $.ajax 方法執行資料作業。
在新客戶記錄上依序執行作業。

當您執行範例，可以選擇刪除已建立的記錄。
預覽 Web 資源時，顯示類似下列的結果：sample_/JQueryRESTDataOperations.htm
1. 將主要連絡人設定為：<系統中第一個連絡人記錄的全名>。
2. 將偏好的連絡方法設定為電子郵件。
3. 將年度營收設定為兩百萬。
4. 將連絡人方式電話設定為「不允許」。
5. 客戶名稱「Test Account Name」是以 AccountId：「7780cef2-fdf4-e011-9d26-00155dba3819」建立的。
6. 擷取具有 AccountId："7780cef2-fdf4-e011-9d26-00155dba3819" 的客戶。
7. 擷取名為 "Test Account Name" 的客戶。此客戶建立時間：「2011 年 10 月 12 日星期三 11:13:56 PDT」。
8. 變更客戶名稱為 "Updated Account Name"。
9. 新增地址資訊。
10. 設定電子郵件地址。
11. 客戶記錄變更已儲存
12. 您選擇刪除客戶記錄。
13. 客戶已刪除。

如果您選擇不刪除客戶，會看到連結開啟剛才建立的記錄。
