使用Visual Studio和Selenium,我试图将鼠标悬停在下拉菜单中的某个元素上,以便可以单击其中的“隐藏”元素。不能仅单击,我必须将鼠标悬停。
我尝试了几种不同的方法但没有成功:
首先,我试图将鼠标悬停在这样的第一个元素上:
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();
此方法使第一个下拉菜单元素被“标记”,但由于某种原因该下拉菜单没有打开,因此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,并在同一命令中也单击第二个元素:
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。第一个元素甚至都没有被“标记”。测试仅在10秒后超时。
所以现在我正尝试使用定位器:
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);
但是我无法执行此测试,因为IWebDriver不包含单击的定义。尝试编写时出现此错误:
driver.click
有什么建议吗?
第一个元素:
By.XPath("//span[contains(@class,'item-text')][contains(text(),'Change')]"
第二个元素:
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:
<div class="topbar-menu-dd responsive-dropdown-menu add">
<div class="scrollable-dropdown-menu scrollable-dropdown-menu-root dropdown-
menu dropdown-menu-root dropdown-menu dropdown-menu-root dropdown
dropdown-root responsive-dropdown-menu-root active">

我通常为C#Selenium使用定制的单击功能。
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;
}
根据我的经验,以上3种方法中至少有一种适用于所有情况。 此外,我们可以通过检查函数的返回值来检查是否发生异常。 您可以按以下方式使用此功能。
By first = By.XPath("//span[contains(@class,'item-text')][contains(text(),'Change')]";
if(!await TryClick(first,0)) // If this does not work, try 1 and 2 for the second parameter
{
// Failed to click
}
By second = By.XPath("//span[contains(@class,'item-text')][contains(text(),'Create Change Order')]";
if(!await TryClick(second,0)) // If this does not work, try 1 and 2 for the second parameter
{
// Failed to click
}
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并说明要实现的目标,那么寻求帮助会更好。

仅使用悬停(MoveToElement
)不足以激活和展开下拉菜单。我还需要使用MoveByOffset
稍微移动鼠标。
展开菜单后,单击第二个元素就没有问题。
//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();
