如何处理StaleElementReferenceException (Selenium )？
提问于 2022-04-10 06:58:30
我正在使用python中的selenium为https://etherscan.io/编写一个刮板。在我的代码中，当StaleElementReferenceException单击一个按钮而没有找到任何解决此错误的好源时，它就会在代码中得到它。
这是密码
url = "https://etherscan.io/login?"
driver.implicitly_wait(30)
driver.get(url)
username = driver.find_element_by_xpath('//*[@id="ContentPlaceHolder1_txtUserName"]')
username.send_keys('user')
password = driver.find_element_by_xpath('//*[@id="ContentPlaceHolder1_txtPassword"]')
password.send_keys('pass')
login = driver.find_element_by_xpath('//*[@id="ContentPlaceHolder1_btnLogin"]')
login.click()
more = driver.find_element_by_xpath('//*[@id="moreMegaMenu"]')
more.click()
word_cloud = driver.find_element_by_xpath('//*[@id="LI41"]/a').click()
soup = BeautifulSoup(driver.page_source, 'html.parser')
wait = WebDriverWait(driver, 10)
dropdown = driver.find_elements_by_css_selector('.dropdown-toggle')
for ele in dropdown:
ele.click()
time.sleep(1)
account = wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR,'.d-block')))
driver.execute_script("arguments[0].click();", account)
time.sleep(1)
driver.execute_script("window.history.go(-1)")错误信息：

@cruisepandey解决方案是可以的，但我认为我的解决方案更简单一些。而且，在我的例子中，他的解决方案重定向到错误的页面(到主页)。
url = "https://etherscan.io/login?"
driver.implicitly_wait(30)
driver.get(url)
username = driver.find_element_by_xpath('//*[@id="ContentPlaceHolder1_txtUserName"]')
username.send_keys('user')
password = driver.find_element_by_xpath('//*[@id="ContentPlaceHolder1_txtPassword"]')
password.send_keys('pass')
login = driver.find_element_by_xpath('//*[@id="ContentPlaceHolder1_btnLogin"]')
login.click()
more = driver.find_element_by_xpath('//*[@id="moreMegaMenu"]')
more.click()
word_cloud = driver.find_element_by_xpath('//*[@id="LI41"]/a').click()
soup = BeautifulSoup(driver.page_source, 'html.parser')
wait = WebDriverWait(driver, 10)
num_elements = len(driver.find_elements_by_css_selector('.dropdown-toggle'))
for i in range(num_elements):
ele = driver.find_elements_by_css_selector('.dropdown-toggle')[i]
ele.click()
time.sleep(1)
account = wait.until(EC.element_to_be_clickable((By.XPATH, f'//*[@id="content"]/div[3]/div/div/div[3]/div[{i+1}]/div/div/a[1]')))
driver.execute_script("arguments[0].click();", account)
time.sleep(1)
driver.execute_script("window.history.go(-1)")
