備註

如需 Deferral 類別的詳細資訊，請參閱 應用程式生命週期 中的延遲和 ExtendedExecution 範例一節。

完成 DeferralCompletedHandler之前，JAVAscript 應用程式不應該允許流覽。 這樣做可能會導致應用程式當機，而且應該被視為程式設計錯誤。

建構函式

Deferral(DeferralCompletedHandler)

初始化新的 Deferral 物件，並指定要在延遲完成時呼叫的 DeferralCompletedHandler 。

方法

Close()

如果尚未叫用 DeferralCompletedHandler ，這會呼叫它，並卸載委派的參考。
Complete()

如果尚未叫用 DeferralCompletedHandler ，這會呼叫它，並卸載委派的參考。
Dispose()

執行與釋放 (Free)、釋放 (Release) 或重設 Unmanaged 資源相關聯之應用程式定義的工作。
