使用 SeleniumBasic for vba 选择隐藏菜单项时遇到问题

Question

我在使用SeleniumBasic for vba 在工作网页上选择隐藏菜单项时遇到了一些问题。我尝试使用WebDriver.Mouse.MouseTo 将鼠标悬停在每个菜单选项上，以便我可以选择嵌套在它“下方”的对象，但在第一次悬停后找不到该对象。

在下图中我打算这样导航：

Pricing Admin
    System Admin
        Multi-PAG Upload

为此，我必须将鼠标悬停在 Pricing Admin 上，然后将鼠标悬停在 System Admin 上，这样菜单才会出现点击Multi-PAG Upload强>。我已成功让驱动程序将鼠标悬停在 Pricing Admin 上，这会显示第一个菜单列表，其中包含以 System Admin 结尾的三个项目。但是，为 System Admin 尝试 FindElement() 以便我可以将鼠标悬停在它上面已被证明非常困难。

根据我尝试的方法，我倾向于收到object required 错误或XPath selector invalid。我在Set systemAdmin = 开始遇到问题。

欢迎任何建议！

Public Sub SeleniumTest()

    Dim driver As New WebDriver

    'open chrome to site
    driver.start "chrome"
    driver.Get "http://www.website.net"

    'login
    driver.FindElementByName("j_username").SendKeys ("user")
    driver.FindElementByName("j_password").SendKeys ("pass")
    driver.FindElementById("submit_button").Click


    'hover over Pricing Admin
    Dim pricingAdmin As WebElement
    Set pricingAdmin = driver.FindElementById("prcngAdmMnuFrm:prcngAdmMnu")

    driver.Mouse.MoveTo pricingAdmin


    Dim systemAdmin As WebElement
    'neither selection method below works properly
'   Set systemAdmin = driver.FindElementByXPath("//*[contains(text(),'System Admin')]")
'   Set systemAdmin = driver.FindElementByXPath("//div[@id='prcngAdmMnuFrm:prcngAdmMnu']/div/div/ul/li/ul/li[3]/ul/li[4]/a/span/span")

    driver.Mouse.MoveTo systemAdmin


    Dim multiPagUpload As WebElement
'   Set multiPagUpload = driver.FindElement("??")

    multiPagUpload.Click


    'closes browser window
    driver.Quit

End Sub

这里是网站的（删节的）HTML。为简单起见，我删除了一些列表，但如果确实有必要（使用 javascript 等），请告诉我，我可以添加更多内容。

如果我遗漏了您需要解决的任何问题，请告诉我！

Answer 1

代码中使用的 xpath 不正确。我建议找到锚元素并将鼠标移到上方。

#系统管理员菜单

'Hover over Pricing Admin
Dim systemAdmin As WebElement
Set systemAdmin = driver.FindElementByXPath("//a[.//span[contains(.,'System Admin')]]")

driver.Mouse.MoveTo pricingAdmin

如果鼠标悬停不起作用，我们仍然可以尝试通过点击锚元素然后发送keys（keys.Arrow_Right）来处理菜单

#Multi-PAG 上传

Dim multiPagUpload As WebElement
Set multiPagUpload = driver.FindElementByXPath("//a[.//span[contains(.,'Multi-PAG Upload')]]")

multiPagUpload.Click
