使用型別和資源名稱,向 Page 物件註冊用戶端指令碼資源。
public:
void RegisterClientScriptResource(Type ^ type, System::String ^ resourceName);
public void RegisterClientScriptResource (Type type, string resourceName);
member this.RegisterClientScriptResource : Type * string -> unit
Public Sub RegisterClientScriptResource (type As Type, resourceName As String)
參數
- type
- Type
要註冊的用戶端指令碼資源類別。
- resourceName
- String
要註冊的用戶端指令碼資源名稱。

下列程式碼範例示範如何以程式設計方式套用 WebResourceAttribute 中繼資料屬性,以標記要提供之資源的元件。
using System;
using System.Web;
using System.Web.UI;
using System.Security.Permissions;
[assembly: WebResource("Samples.AspNet.CS.Controls.script_include.js", "application/x-javascript")]
namespace Samples.AspNet.CS.Controls
{
[AspNetHostingPermission(SecurityAction.Demand, Level = AspNetHostingPermissionLevel.Minimal)]
public class ClientScriptResourceLabel
{
// Class code goes here.
}
}
Imports System.Web
Imports System.Web.UI
Imports System.Security.Permissions
<Assembly: WebResource("Samples.AspNet.VB.Controls.script_include.js", "application/x-javascript")>
Namespace Samples.AspNet.VB.Controls
<AspNetHostingPermission(SecurityAction.Demand, Level:=AspNetHostingPermissionLevel.Minimal)> _
Public Class ClientScriptResourceLabel
' Class code goes here.
End Class
End Namespace
此範例需要名為 的 Script_include.js
JavaScript 檔案,其中包含下列內容:
function DoClick() {Form1.Message.value='Text from resource script.'}
將 Script_include.js
檔案編譯為包含 ClientScriptResourceLabel
類別之 Samples.AspNet.CS.Controls
元件中的資源。
備註
RegisterClientScriptResource透過 WebResource.axd HTTP 處理常式從元件存取已編譯的資源時,會使用 方法。 方法 RegisterClientScriptResource 會向 Page 物件註冊腳本,並防止重複的腳本。 這個方法會將資源 URL 的內容與 <script>
專案區塊包裝。
