Python 找不到要单击的元素-selenium

我正在尝试在收到电子邮件后自动更新服务台票据。我已经找到了“倾听”电子邮件并启动网站/登录的方法，但是对于我来说，我认为最简单的部分之一就是最困难的部分。基本上，我需要单击下图中的下拉列表，然后键入或单击“确认”选项

带有下拉选项的服务台照片：

下面是下拉列表的代码片段，注意：代码中ID中的数字根据票证的不同而变化。在本例中，数字是298

但我总是会收到错误，说明找不到元素。有什么想法吗？

您可能想与select元素交互。它们的工作方式不同于所有其他元素，并且有一个特定的Selenium库来处理它们。这里可能是完成你想做的事情最简单的方法。不过要注意，我不知道为什么在网页上找不到该元素——这是您首先要得到的答案。为此，如果页面呈现时默认不可见，我会确保它已滚动到视图中。您可能有超时问题等

from selenium.webdriver.support.select import Select
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

timeout = 15
try:
    status_select = WebDriverWait(self.thread.driver, timeout).until(
        EC.visibility_of_element_located(("id", "status"))
    )
    Select(status_select).select_by_value("Acknowledged")
except:
    print("Element was not visible on page after", timeout, "seconds.")

根据您共享的HTML，您需要单击下图中的下拉列表，然后单击“确认”选项，您可以使用以下代码块：

driver.find_element_by_xpath("//div[@class='newListSelected status_CustomSelect']/input[@class='autoSuggestInput' and @type='text']").click()
driver.find_element_by_xpath("//div[@class='newListSelected status_CustomSelect']/input[@class='autoSuggestInput' and @type='text']//following::ul[@class='newList']/li[@class='option_39_option']").click()

从您的HTML代码中，我可以知道您想要操作的不是HTML的原生select use标记，实际上它是一个模拟的select，它的UI和行为看起来像原生select

要操作模拟选择，您需要执行以下步骤：

确定单击哪个元素将显示所有选项 找出所有选项的HTML代码，这样您就可以编写定位器来查找您想要选择的选项。 从您的HTML代码中，我无法确切地知道上面步骤1中所述元素的HTML代码。但是从截图上看，我想除了“请选择状态”之外的向下箭头应该是我们想要的

从您的HTML代码中，我可以找到所有选项的HTML代码，它们如下所示：

请选择一个状态 刚出现的 关闭 提交错误 悬而未决的 删除 请求被拒绝 正在进行的工作 断然的 承认

from selenium.webdriver.support.select import Select
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

timeout = 15
try:
    status_select = WebDriverWait(self.thread.driver, timeout).until(
        EC.visibility_of_element_located(("id", "status"))
    )
    Select(status_select).select_by_value("Acknowledged")
except:
    print("Element was not visible on page after", timeout, "seconds.")

driver.find_element_by_xpath("//div[@class='newListSelected status_CustomSelect']/input[@class='autoSuggestInput' and @type='text']").click()
driver.find_element_by_xpath("//div[@class='newListSelected status_CustomSelect']/input[@class='autoSuggestInput' and @type='text']//following::ul[@class='newList']/li[@class='option_39_option']").click()
