HtmlElementEventHandler

範例

下列程式碼範例示範此成員的使用。 在此範例中，事件處理常式會報告事件發生次數 MouseUp 。 此報告可協助您瞭解事件發生的時間，並可協助您進行偵錯。 若要報告多個事件或經常發生的事件，請考慮將 取代 MessageBox.ShowConsole.WriteLine 為 或將訊息附加至多行 TextBox 。

若要執行範例程式碼，請將它貼到包含名為 HtmlElement1 之型 HtmlElement 別實例的專案。 然後，確定事件處理常式與事件相關聯 MouseUp 。

private void HtmlElement1_MouseUp(Object sender, HtmlElementEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "MouseButtonsPressed", e.MouseButtonsPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ClientMousePosition", e.ClientMousePosition );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "OffsetMousePosition", e.OffsetMousePosition );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "MousePosition", e.MousePosition );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "BubbleEvent", e.BubbleEvent );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "KeyPressedCode", e.KeyPressedCode );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "AltKeyPressed", e.AltKeyPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "CtrlKeyPressed", e.CtrlKeyPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ShiftKeyPressed", e.ShiftKeyPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "EventType", e.EventType );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ReturnValue", e.ReturnValue );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "FromElement", e.FromElement );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ToElement", e.ToElement );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "MouseUp Event" );
}

Private Sub HtmlElement1_MouseUp(sender as Object, e as HtmlElementEventArgs) _ 
     Handles HtmlElement1.MouseUp

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "MouseButtonsPressed", e.MouseButtonsPressed)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ClientMousePosition", e.ClientMousePosition)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "OffsetMousePosition", e.OffsetMousePosition)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "MousePosition", e.MousePosition)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "BubbleEvent", e.BubbleEvent)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "KeyPressedCode", e.KeyPressedCode)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "AltKeyPressed", e.AltKeyPressed)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "CtrlKeyPressed", e.CtrlKeyPressed)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ShiftKeyPressed", e.ShiftKeyPressed)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "EventType", e.EventType)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ReturnValue", e.ReturnValue)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "FromElement", e.FromElement)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ToElement", e.ToElement)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"MouseUp Event")

End Sub

備註

您可以將 類別的 HtmlElementEventArgs 屬性設定 ReturnValue 為 true ，以取消專案上事件的預設動作 MouseUp 。

MouseUp除非您將 類別的 HtmlElementEventArgs 屬性設定 BubbleEvent 為 true ，否則元素上的事件也會發生在該專案的父元素和 HtmlDocument 類別本身上。
