在 Safari 浏览器上，我需要从下拉列表中选择一个选项，但有趣的是它适用于除 Mac OS 上的 Safari 之外的所有浏览器。我正在使用 Safari 10.0.3 和 selenium webdriver 版本 3.3.0

我已经用 C# 编写了代码。请参阅下面的代码 -

    IWebDriver driver;
    driver = new SafariDriver();
    List<string> handles = driver.WindowHandles.ToList<string>();
    driver.SwitchTo().Window(handles.First());
    driver.Navigate().GoToUrl("https://myip/MyPage.aspx");
    SelectElement element = new SelectElement(driver.FindElement(By.Id("securityQuestion")));
    int totalOptions = element.Options.Count;
    Random rnd = new Random();
    int rndValue = rnd.Next(1, totalOptions);
    element.SelectByIndex(rndValue); // This is not working for Safari browser      
    driver.FindElement(By.Id("securityAnswer")).SendKeys("test");
    driver.FindElement(By.Id("ctl00_Content_btnNext")).Click();
    driver.Close();

没有错误只是因为它没有从下拉列表中选择任何值。

这是一个 safaridriver 错误。修复在 WebKit 中，并在此处进行跟踪： https ://bugs.webkit.org/show_bug.cgi?id=174710

作为一种解决方法，您可以使用 JavaScript 和 DOM API 修改选择的哪些选项。

在此处尝试此示例以获取 JS 解决方法 - 作为 C# 扩展实现。此代码适用于 Safari（在 10.1+ 版本上测试）。

这不是完整的代码，只是一个使其简单的片段。您可以扩展它以支持您喜欢的任何功能。
