如何在網頁 http://architects-register.org.uk/list/regions 中使用 Selenium 和 Python 點擊按鈕 A 到 Z

Question

http://architects-register.org.uk/list/regions

所以我有這個網站，我希望能夠讓代碼點擊按鈕 A，然后是 B 和 C 等等。 我該怎么做。 我嘗試了這段代碼，它試圖獲取元素子元素的值，然后相應地單擊按鈕，但它不起作用。 我懷疑除了下面的錯誤之外還有其他一些問題。

from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Firefox()

url = 'http://architects-register.org.uk/'
driver.get(url)

find_uk = driver.find_element_by_id('ctl00_hlCountiesT').click()

elements = alphabets[0].find_element_by_tag_name('li')

def getChild(el):
   return el.children[0].children[0]

for element in elements:
    element = element[elements]
    (getChild(element)).click()

NameError: name 'alphabets' is not defined

Answer 1

沒有在給定代碼塊中的任何地方導入或定義alphabets ，因此嘗試訪問其上的索引將按所示方式失敗。 看起來alphabets應該可能是調用find_elements_by_tag_name或find_elements_by_class_name的結果，這將返回您的按鈕列表，然后您可以遍歷並單擊該列表。

Answer 2

誘導WebDriverWait和visibility_of_all_elements_located () 然后點擊每個鏈接。

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium import webdriver

driver = webdriver.Firefox()
url = 'http://architects-register.org.uk/'
driver.get(url)
WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.ID,"ctl00_hlCountiesT"))).click()
elements =WebDriverWait(driver,10).until(EC.visibility_of_all_elements_located((By.XPATH,"//div[@class='alphabet_list_content']//li//input")))
for ele in range(len(elements)):
    elements = WebDriverWait(driver,10).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='alphabet_list_content']//li//input")))
    elements[ele].click()

Answer 3

要單擊按鈕A ，然后單擊B和C等等，您必須為element_to_be_clickable()誘導WebDriverWait並且您可以使用以下任一定位器策略：

• 使用CSS_SELECTOR ：

   driver.get("http://architects-register.org.uk/list/regions") for i in range(1, len(WebDriverWait(driver, 5).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div.alphabet_list_content>ul li"))))): WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.alphabet_list_content>ul li:nth-of-type({})>a>input".format(i)))).click() driver.quit()

• 使用XPATH ：

   driver.get("http://architects-register.org.uk/list/regions") for i in range(1, len(WebDriverWait(driver, 5).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='alphabet_list_content']/ul//li"))))): WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='alphabet_list_content']/ul//following-sibling::li[{}]/a/input".format(i)))).click() driver.quit()

• 注意：您必須添加以下導入：

   from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC
