Question

更新：这是我无法切换到的帧的屏幕截图： frame that cannot be located

我尝试了多种选择此元素的方法，但始终会收到“无法定位”错误。

我可以轻松地在大多数页面上找到元素，但是我怀疑此html需要额外的一两个步骤才能获得链接。

这是html，链接位于第三行：

<div class="menu_bg">
    <ul class="menu">
        <li id="retrieve"><a href="https://s1.ebridge.com/ebridge/3.0/retrieve/search.aspx?search=new&amp;guid=4ae139ed-287a-4087-8fe0-56ff3683e160" id="aView" onclick="clickme(this,'retrieve')" target="main">Retrieve</a></li>
        <li id="help"><a id="aSupport" onclick="clickme(this,'reports')" target="main" href="Support/support_main.aspx?guid=4ae139ed-287a-4087-8fe0-56ff3683e160">Support</a></li>
        <li style="float: right;">
            <span id="cabnm" class="cabinet_box">PinCHD</span>
        </li>
    </ul>
</div>

此元素位于login page here后面的页面上，使用以下代码登录时我没有问题：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from bs4 import BeautifulSoup
import re
import pandas as pd
import os
from selenium.webdriver.common.by import By
url = "https://s1.ebridge.com/ebridge/3.0/default.aspx?1"
driver = webdriver.Firefox(executable_path="/Applications/Postgres.app/Contents/Versions/11/bin/geckodriver")
driver.implicitly_wait(30)
driver.get(url)
username = driver.find_element_by_name("tbUserName")
username.clear()
username.send_keys("public")
password = driver.find_element_by_name("tbPassword")
password.clear()
password.send_keys("public")
file_cabinet = driver.find_element_by_name("tbFileCabinet")
file_cabinet.clear()
file_cabinet.send_keys("PINCHD")
file_cabinet.send_keys(Keys.RETURN)

运行此命令后，包含链接的页面难以定位负载。我尝试通过id，xpath，css选择器，链接文本和部分链接文本查找失败。

我希望有人可以查看我问题顶部的html，并告诉我他们如何在第三行中找到链接，以便我可以点击（）。

Answer 1

您要查找的元素在框架内，因此首先需要切换到该框架，然后搜索这样的元素。

driver.switch_to.frame('header')  #Match by name of the frame
my_element = driver.find_element_by_xpath('//*[@id="aView"]')
my_element.click()

在这里回答我自己的问题：

问题出在Firefox（geckodriver）网络驱动程序上。使用Chrome驱动程序时没有遇到任何问题。
