範例
複製下列 HTML 並將它儲存到名為 orderForm.htm 的表單中：
<HTML>
<BODY>
<FORM name="NewOrderForm">
Select Part Type:
<SELECT name="PartType">
<OPTION>AZ-3700
<OPTION>AZ-3701
<OPTION>AZ-3702
</SELECT><br/>
Quantity: <INPUT type="text" name="PartQty" size="2" maxsize="2" /><br/>
Building/Desk:
<INPUT type="text" name="PartBuilding" size="2" maxsize="2"/> /
<INPUT type="text" name="PartDesk" size="2" maxsize="2"/><p/>
<INPUT type="submit" value="Transmit Order"/>
</FORM>
</BODY>
</HTML>
下列範例會在使用者提交 NewOrderForm 時顯示 Confirm 對話方塊。
HtmlWindow orderWindow;
HtmlElement formElement;
private void LoadOrderForm()
{
if (!(webBrowser1.Document == null))
{
HtmlDocument doc = webBrowser1.Document;
orderWindow = doc.Window.OpenNew(new Uri("file://C:\\orderForm.htm"), "");
//!TODO: Perform this in the load event handler!
// Get order form.
HtmlElementCollection elemCollection = doc.All.GetElementsByName("NewOrderForm");
if (elemCollection.Count == 1)
{
formElement = elemCollection[0];
//!TODO: Awaiting DCR
//formElement.AttachEventHandler("onsubmit", new HtmlElementEventHandler(Form_Submit));
}
}
}
private void Form_Submit(object sender, HtmlElementEventArgs e)
{
bool doOrder = orderWindow.Confirm("Once you transmit this order, you cannot cancel it. Submit?");
if (!doOrder)
{
//Cancel the submit.
e.ReturnValue = false;
orderWindow.Alert("Submit cancelled.");
}
}
Dim OrderWindow As HtmlWindow
Dim FormElement As HtmlElement
Private Sub NewOrderButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NewOrderButton.Click
LoadOrderForm()
End Sub
Private Sub LoadOrderForm()
If (WebBrowser1.Document IsNot Nothing) Then
With WebBrowser1.Document
OrderWindow = .Window.OpenNew(New Uri("file://C:\\orderForm.htm"), "")
' !TODO: Perform this in the load event handler!
' Get order form.
Dim ElemCollection As System.Windows.Forms.HtmlElementCollection = .All.GetElementsByName("NewOrderForm")
If (ElemCollection.Count = 1) Then
FormElement = ElemCollection(0)
' TODO: Resolve this.
'FormElement.AttachEventHandler("onsubmit", New HtmlElementEventHandler(AddressOf Form_Submit))
End If
End With
End If
End Sub
Private Sub Form_Submit(ByVal sender As Object, ByVal e As HtmlElementEventArgs)
Dim DoOrder As Boolean = OrderWindow.Confirm("Once you transmit this order, you cannot cancel it. Submit?")
If (Not DoOrder) Then
' Cancel the submit.
e.ReturnValue = False
OrderWindow.Alert("Submit cancelled.")
End If
End Sub
備註
Confirm 會顯示強制回應對話方塊;使用者無法存取基礎 HTML 頁面，而不需要先關閉此對話方塊。
