我正在尝试编写一个 Python 脚本来自动从我的路由器站点 (10.0.0.2) 更改我的 Wi-Fi 密码。我正在使用 Selenium，但由于找不到某些元素而一直碰壁。非常感谢您的帮助。我将在下面提供所有必要的调试资源:
我通过 XPath 查找元素成功登录到我的路由器。
找到提交/登录按钮并单击它:
browser.find_element_by_xpath('//input[@type="submit"]').send_keys(Keys.ENTER)`
另外，我尝试了几种方法来查找该元素，但我暂时将它们注释掉了。
#Locate Advanced Tab --1
browser.find_element_by_name("Advanced").click()
#Locate Advanced Tab --2
#tt1 = browser.find_element_by_xpath("//td[@id='topnav1']")
#tt1.click()
[1]#Locates the the advance tab on the page -- 3
#adv = browser.find_element_by_id('topnav1')
#adv.send_keys(Keys.RETURN)
这是我路由器中“高级”选项卡的代码:
<td id="topnav1" class="topnavoff" width="140"><a href="javascript:ontopnav('1')">Advanced</a></td>
已编辑:分别是代码和错误。

最佳答案
点击link文本为 Advanced 您可以使用以下任何一行代码:
css_selector:browser.find_element_by_css_selector("table#topnav_container2 tr td.topnavoff#topnav1 > a").click()xpath:browser.find_element_by_xpath("//table[@id='topnav_container2']//tr//td[@class='topnavoff' and @id='topnav1']/[contains(.,'Advanced')]").click()
Note : The
linkwith text asAdvancedis within an<a>tag. Hence you must try to invoke the powerful click() method instead ofsend_keys(Keys.RETURN)orsend_keys(Keys.ENTER)as follows :
browser.find_element_by_link_text("Advanced").click()
