Question

如何从iframe中查找所有链接？我在Selenium和C＃中尝试过的以下代码以及其他一些变体，但是错误消息指出未找到此类元素：

var detailFrame = Driver.driver.FindElement(By.Id("twitter - widget - 0"));
Driver.driver.SwitchTo().Frame(detailFrame);
var linksTweetContents = Driver.driver.FindElements(By.XPath("/ol[@class='timeline-TweetList']//a"));
Driver.driver.SwitchTo().DefaultContent();

这是我使用过的SO链接：Selenium: Unable to access iframe and data inside it

我已经给出了html结构的尽可能多的细节，以显示所涉及的复杂性。希望得到您的反馈。

Answer 1

根据您共享的 HTML 来查找所需的 WebElements ，您必须：

诱导 WebDriverWait 使所需的框架可用并切换到该框架。

诱导 WebDriverWait 以使所需的元素可见，并且您可以使用以下任一解决方案：

使用FrameToBeAvailableAndSwitchToIt(By.CssSelector())：

new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(By.CssSelector("iframe#twitter-widget-0")));
var linksTweetContents = new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.VisibilityOfAllElementsLocatedBy(By.CssSelector("ol.timeline-TweetList a")));

使用FrameToBeAvailableAndSwitchToIt(By.XPath())：

new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(By.XPath("//iframe[@id='twitter-widget-0']")));
var linksTweetContents = new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.VisibilityOfAllElementsLocatedBy(By.XPath("//ol[@class='timeline-TweetList']//a")));
