我正在尝试在同一窗口中生成的弹出窗口中选择无线按钮。它不会生成任何iFrame，也无法在此Wifi-Connect窗口中找到任何元素。
有人有任何想法吗？
我试过了
driver.find_element_by_xpath(".//*[@id='ext-gen1481']/div/li[2]/div/a"
我也尝试过CSS。
代码我试图选择：
<img class="x-tree-node-icon nsm-wifi-icon-wireless" unselectable="on" src="/scripts/ext-3/resources/images/default/s.gif" alt=""/>
<a class="x-tree-node-anchor" tabindex="1" href="" hidefocus="on">
<span unselectable="on">Wireless</span>

由于文本为无线的元素是JavaScript生成的元素，您需要为element_to_be_clickable()引入WebDriverWait，您可以使用以下Locator Strategy：
XPATH：
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//img[@class='x-tree-node-icon nsm-wifi-icon-wireless']//following::a[1]/span[text()='Wireless']"))).click()
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
在给定的XPath中，您使用id作为第一个参考点。我假设你也用cssSelector做了同样的事情。
由于这些ID是随机生成的，因此每次都不同。例如，您给定的代码和XPath具有不同的ID。
请尝试使用以下CSS选择器，
CSS：
driver.find_elements_by_css_selector("div[ext:tree-node-id='SYNO.SDS.NSMWifi.Wireless.Main'] > a");
XPath的：
driver.find_elements_by_xpath("//div[@ext:tree-node-id='SYNO.SDS.NSMWifi.Wireless.Main']/a");
如果弹出元素不可选，则可能需要切换到活动元素。
如果它没有显示任何定位器，并且它是否在同一个窗口中生成，则可能是一个警报。如果是警报，则只需尝试driver.switchTo（）。alert（）。accept（）或（您想要执行的任何其他操作）。希望有帮助......
