備註

管理文件物件模型 (DOM) 會公開僅選取的事件數目。The Managed Document Object Model (DOM) exposes only a select number of events. 其中大部分未公開的事件只會定義特定類型的項目;這類submit事件,這是只在有效FORM項目。Most of the unexposed events are only defined for specific types of elements; such as the submit event, which is valid only on FORM elements. 使用AttachEventHandler這些未公開的事件加入事件處理常式。Use AttachEventHandler to add an event handler to these unexposed events.

您不應該附加至文件或其中一個物件的事件,直到文件已完成載入。You should not attach an event to the document or one of its objects until the document has completed loading. 您應該呼叫這個方法最舊的處於DocumentCompleted事件的WebBrowser控制項。The earliest you should call this method is in the DocumentCompleted event of the WebBrowser control.
