FirefoxProfile prof = new FirefoxProfile("D:\Documents and Settings\username\Application Data\Mozilla\Firefox\Profiles\myporfile");

try {
    ff.Navigate().GoToUrl("http://exemple.com");
    88:


    try {
        45:

        ff.SwitchTo().Frame("ifrm1");
        ff.SwitchTo().Frame("ifrm2");
    } catch (NoSuchFrameException exx) {
        goto 45;
    }

    try {
        66:
        IWebElement oo = ff.FindElement(By.TagName("a"));
        oo.Click();
        ff.Close();
    } catch (NoSuchElementException ex) {
        goto 66;
    }

} catch (WebDriverTimeoutException ex) {
    goto 88;
}

vb.net

 Dim prof As FirefoxProfile = New FirefoxProfile("D:\Documents and Settings\username\Application Data\Mozilla\Firefox\Profiles\myporfile")
        Dim ff = New FirefoxDriver(New FirefoxBinary("D:\Program Files\Mozilla Firefox\Firefox.exe"), prof, TimeSpan.FromMinutes(10))
        ff.Manage().Timeouts().SetPageLoadTimeout(TimeSpan.FromSeconds(10))



        Try
            ff.Navigate().GoToUrl("http://exemple.com")

88:         Try


45:             ff.SwitchTo().Frame("ifrm1")
                ff.SwitchTo().Frame("ifrm2")
   Catch exx As NoSuchFrameException
                GoTo 45
            End Try
            Try

66:             Dim oo As IWebElement = ff.FindElement(By.TagName("a"))
                oo.Click()
               ff.Close()
              Catch ex As NoSuchElementException
                GoTo 66
            End Try
        Catch ex As WebDriverTimeoutException

            GoTo 88
        End Try

所以我处理超时异常并处理 NoSuchElementException 以检查元素是否可用，但有时会触发，有时不会，

有没有更好的方法:

1-不等document.Ready

2- 监视直到第二个 iframe 内的锚点出现并触发它

感谢帮助！

Answer 1

切换到第二个iframe后，您应该等待带有explicit的元素。但是，您必须确保 Selenium 能够在秒内设置焦点 iframe

//Define the time you want to wait while selenium is looking for the element.
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
IWebElement oo  = wait.Until<IWebElement>((d) =>
{
    return d.FindElement(By.Id("ifrm2"));
});

//iframe found so use switchTo()
ff.SwitchTo().Frame("ifrm2")

Answer 2

好吧，诀窍是，在切换到第一个 iframe 时，第二个尚未加载，我应该切换回默认的主要内容..

ff.Manage().Timeouts().SetPageLoadTimeout(TimeSpan.FromSeconds(5))

//to start the job after 5 second , and skip waiting for all DOM document to be Ready !

   Try
            ff.Navigate().GoToUrl("http://exemple.com")

45         Try
           ff.SwitchTo().DefaultContent() // if ifrm1 is loaded and not iframe 2 , you should switch back to default !
           ff.SwitchTo().Frame("ifrm1")
           ff.SwitchTo().Frame("ifrm2")
           Dim oo As IWebElement = ff.FindElement(By.TagName("a"))
           oo.Click()
           ff.Close()
           Catch ex As Exception
                GoTo 45
            End Try
        Catch ex As WebDriverTimeoutException
//To Skip the wait of all document ...
            GoTo 45
End Try
