Question

enter image description hereenter image description here我在尝试使用 selenium Python 自动化 Web-table 时遇到上述异常。下面是我的代码

import time
from selenium import webdriver
from selenium.common.exceptions import StaleElementReferenceException

driver = webdriver.Chrome("E:\pythonProject\Framefork1\BrowserDrivers\chromedriver.exe")
driver.maximize_window()
driver.get("https://admin-demo.nopcommerce.com/Admin/Customer/List")
driver.find_element_by_xpath("/html/body/div[6]/div/div/div/div/div[2]/div[1]/div/form/div[3]/input").click()

time.sleep(5)
table = driver.find_element_by_xpath("(//table[@class='table table-bordered table-hover table-striped dataTable no-footer'])[2]")
body = table.find_element_by_tag_name("tbody")
cells = body.find_elements_by_tag_name("td")
rows = body.find_elements_by_tag_name("tr")
links = driver.find_elements_by_xpath("//i[@class='fa fa-pencil']")
print(len(rows))

for i in range(len(rows)):
    col = rows[i].find_elements_by_tag_name("td")
    for j in range(len(col)):`enter code here`
        if col[j].text == "Registered":
            time.sleep(5)
            links[i].click()
            driver.find_element_by_link`_text("back to customer list").click()

业务场景我附上文档供参考

Answer 1

selenium 不会为您提供 python 的元素，而是对网络浏览器中当前页面上对象的引用。当您单击并加载新页面时，您将失去对这些对象的访问权。

首先，您必须将所有链接获取为文本，然后将它们与 driver.get()

一起使用

import time
from selenium import webdriver
from selenium.common.exceptions import StaleElementReferenceException

driver = webdriver.Chrome()#"E:\pythonProject\Framefork1\BrowserDrivers\chromedriver.exe")
driver.maximize_window()

driver.get("https://admin-demo.nopcommerce.com/Admin/Customer/List")
driver.find_element_by_xpath("//input[@type='submit']").click()

time.sleep(5)
table = driver.find_element_by_xpath("(//table[@class='table table-bordered table-hover table-striped dataTable no-footer'])[2]")
body = table.find_element_by_tag_name("tbody")
cells = body.find_elements_by_tag_name("td")
rows = body.find_elements_by_tag_name("tr")
#links = driver.find_elements_by_xpath("//i[@class='fa fa-pencil']")
links = driver.find_elements_by_xpath("//a[@class='btn btn-default']")

print(len(rows))

# -- first get all links ---

links_to_click = []

for i in range(len(rows)):
    col = rows[i].find_elements_by_tag_name("td")
    for j in range(len(col)):
        if col[j].text == "Registered":
            links_to_click.append(links[i].get_attribute('href'))

print(links_to_click)

# --- next visit all links ---

for link in links_to_click:
    driver.get(link)
    #driver.find_element_by_link_text("back to customer list").click()
