使用VisualStudio和Selenium,我试图将鼠标悬停在下拉菜单中的某个元素上,以便单击其中的“隐藏”元素。这是不可能的只是点击,我必须悬停

我尝试了几种不同的方法,但没有成功:

首先,我尝试将鼠标悬停在第一个元素上,如下所示:

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
Actions builder = new Actions(driver);
IWebElement hoverElement = wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("xpath adress here')]")));
builder.MoveToElement(hoverElement).Build().Perform();

这个方法使第一个下拉列表元素被“标记”,但由于某种原因,下拉列表没有打开,所以我无法单击第二个元素

然后我尝试将鼠标悬停在第一个元素上,并在同一命令中单击第二个元素:

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
Actions builder = new Actions(driver);
IWebElement hoverElement = wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("xpath adress here')]")));
builder.MoveToElement(hoverElement).MoveToElement(wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("second xpath adress")))).Click().Build().Perform();
这根本不起作用。第一个元素甚至没有被“标记”。测试在10秒后超时

因此,现在我尝试使用定位器:

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
Actions builder = new Actions(driver);
IWebElement hoverElement = wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("xpath adress for first element')]")));
builder.MoveToElement(hoverElement).Perform();
By locator = By.XPath("2nd element xpath");
driver.click(locator);
但我无法执行此测试,因为IWebDriver不包含单击的定义。当我尝试写入以下内容时,会出现此错误:

driver.click
有什么建议吗

第一个要素:

By.XPath("//span[contains(@class,'item-text')][contains(text(),'Change')]"
By.XPath("//span[contains(@class,'item-text')][contains(text(),'Create Change Order')]"
第二个要素:

By.XPath("//span[contains(@class,'item-text')][contains(text(),'Change')]"
By.XPath("//span[contains(@class,'item-text')][contains(text(),'Create Change Order')]"
更新:

悬停下拉菜单部分的HTML结构如下所示:

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
Actions builder = new Actions(driver);
IWebElement hoverElement = wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("xpath adress here')]")));
builder.MoveToElement(hoverElement).Build().Perform();

  • 改变 ::之前
  • ...
    • 改变
    • 创建变更单
    • ...
我添加的“…”表示代码中不相关的其他部分

当我将鼠标悬停在“更改”上时,会显示“创建更改单”,我可以单击它。

我通常使用定制的C#Selenium点击功能

public async Task<bool> TryClick(By by, int mode = 0)
{
   try
   {
       if (mode == 0)
       {
           Driver.ExecuteScript("arguments[0].click('');", ((RemoteWebDriver)Driver).FindElement(by));
       }
       else if (mode == 1)
       {
           Driver.FindElement(by).Click();
       }
       else if (mode == 2)
       {
           Actions action = new Actions(Driver);
           action.MoveToElement(Driver.FindElement(by)).Perform();
           action.Click(Driver.FindElement(by)).Perform();
       }

       return true;
   }
   catch (Exception ex) { }
   return false;
}
我不确定这是否有帮助。 但是正如@Somber所提到的,如果您共享URL并解释要实现什么,那么获得帮助会更好。

仅使用悬停(
MoveToElement
)不足以激活和扩展下拉菜单。我还需要使用
MoveByOffset
稍微移动鼠标

菜单展开后,单击第二个元素没有问题

//1. Hover mouse over "Change" and move it slightly to the left to open up the menu
var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
var DropDown1 = wait.Until(ExpectedConditions.ElementIsVisible(By.XPath("//span[contains(@class,'item-text')][contains(text(),'Change')]")));
Actions action = new Actions(driver);
action.MoveToElement(DropDown1).Perform();
action.MoveByOffset(-10, -10).Perform();

//2. Click on "Create Change Order"
wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath("//span[contains(@class,'item-text')][contains(text(),'Create Change Order')]"))).Click();


显示您的元素代码显示您的元素HTML代码无法理解其结构。为什么您必须将鼠标悬停在某个位置,而不是单击某个下拉菜单,然后再单击某个菜单项?@Somber单击无法打开下拉菜单中的不同列表项,单击时不会发生任何情况,您必须将鼠标光标悬停在要展开的列表项上。我在问题中添加了HTML结构。我尝试按照您的建议使用操作,但出现了一个错误:“Message:OpenQA.Selenium.WebDriverException:javascript错误:无法读取未定义”的“left”属性,不确定这意味着什么。我还试着按照您的建议使用“Driver.ExecuteScript”,但我的驱动程序不包含“ExcecuteScript”。如果你想看一看,我已经用部分HTML代码更新了这个问题。你能分享这个链接吗?我想先在我这边测试一下。不幸的是不可能。该页面只能通过我工作的公司访问。
