WatiN处理确认对话框在Firefox

我在SO上发现这段代码可以自动取消确认对话框，但它在Firefox中不起作用。

问题是，var windowButton = new WindowsEnumerator().GetChildWindows(window.Hwnd, w => w.ClassName == "Button" && new WinButton(w.Hwnd).Title == "OK").FirstOrDefault();

总是返回null。是否有其他方法可以在firefox中获得对话框按钮的句柄?

public class OKDialogHandler : BaseDialogHandler {
public override bool HandleDialog(Window window) {
    var button = GetOKButton(window);
    if (button != null) {
        button.Click();
        return true;
    } else {
        return false;
    }
}
public override bool CanHandleDialog(Window window) {
    return GetOKButton(window) != null;
}
private WinButton GetOKButton(Window window) {
    var windowButton = new WindowsEnumerator().GetChildWindows(window.Hwnd, w => w.ClassName == "Button" 
        && new WinButton(w.Hwnd).Title == "OK").FirstOrDefault();

    if (windowButton == null)
        return null;
    else
        return new WinButton(windowButton.Hwnd);
 }
}

WatiN处理确认对话框在Firefox

Firefox alert()对话框中的控件是不可枚举的。也就是说，它们不像IE那样作为单独的窗口存在。最好的方法是创建一个新的DialogHandler类来实现IDialogHandler。在构造函数中，可以传入出现对话框的Firefox实例，并且可以使用以下代码将JavaScript发送到Firefox以操纵对话框:

FFDocument nativeDoc = firefox.NativeDocument as FFDocument;
// ClientPort has several WriteAndRead... functions, 
// and takes a variable list of arguments for the script 
// to be executed.
nativeDoc.ClientPort.WriteAndRead(script);

您可以使用下面的JavaScript来单击警报()或确认()对话框中的OK和Cancel按钮。

private const string DialogIsConfirmScript = "typeof getWindows()[{0}].document.documentElement.getButton('accept') !== 'undefined' && typeof getWindows()[{0}].document.documentElement.getButton('cancel') !== 'undefined';";
private const string DialogIsAlertScript = "typeof getWindows()[{0}].document.documentElement.getButton('accept') !== 'undefined' && typeof getWindows()[{0}].document.documentElement.getButton('cancel') !== 'undefined' && getWindows()[{0}].document.documentElement.getButton('cancel').hidden;";
private const string ClickCancelButtonScript = "getWindows()[{0}].document.documentElement.getButton('cancel').click()";
private const string ClickOKButtonScript = "getWindows()[{0}].document.documentElement.getButton('accept').click()";
private const string WindowClassName = "MozillaDialogClass";

一个更完整的实现，将本地IE alert()和confirm()处理封装在一个公共接口中，并添加Firefox处理，可以在http://pastebin.com/ZapXr9Yf
