Question

我一直在寻找这个问题的解决方案。我无法获得用户电子邮件字段的元素。我试过等待元素，页面工厂和其他解决方案，但没有任何对我有用，Selenium仍然抛出两个错误：

 the element is not visible OR stable element problem.

如果有人可以帮助我，我认为更容易直接尝试original page

非常感谢你。

处理完成，退出代码为255

Answer 1

这可能是各种各样的事情。

元素不在您的视口中

你可以这样解决：

driver.maximize_window()

尝试通过xpath搜索

有时，您尝试搜索同一属性下的多个元素，而您只是使用了错误的元素。您可以通过谷歌浏览器或任何其他网络浏览器上的检查元素获取xpath。

很可能元素尚未加载

您可以使用隐式等待来确保元素已加载：

Driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);

隐式等待是告诉WebDriver在尝试查找一个或多个元素（如果它们不是立即可用）时轮询DOM一段时间。默认设置为0.设置后，将为WebDriver对象实例的生命周期设置隐式等待。

Answer 2

以下是您的问题的答案：

在LoginPageWithFactory班级中，要识别Email字段，您提供的xpath即//input[@type='email']不是唯一的。您可以考虑以下代码行来标识Email字段：

@FindBy(xpath= "//form[@id='log-in-form']/input[@type='email']")

如果这回答你的问题，请告诉我。

在Selenium Java上找到一个元素
