如何使用Selenium和Python在网页中单击按钮A到Zhttp://architects-register.org.uk/list/regions

所以我有这个网站，我想让代码点击按钮A，然后B和C等等。我该怎么做呢。我尝试了这段代码，它试图获取元素子元素的值，然后相应地单击按钮，但它不起作用。除了下面的错误之外，我怀疑还有其他一些问题

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()

---

name错误：名称“alphabets”未定义

字母表

未导入或定义在给定代码块中的任何位置，因此尝试访问其索引将以所示方式失败。它看起来像是

字母表

可能是调用

按标签名查找元素

或

按类名查找元素

的结果，这将返回一个按钮列表，然后您可以重复并单击该列表。

所有元素的可见性

（）然后单击每个链接

from selenium.webdriver.common.by import By

from selenium.webdriver.support import expected_conditions as EC
from selenium import webdriver

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

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()

导入位于的所有元素的

WebDriverWait

和

可见性（），然后单击每个链接

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()

要单击按钮A，然后单击按钮B和C等等，您必须使
元素的WebDriverWait可单击（）
，并且您可以使用以下任一选项：


使用
CSS\u选择器
：

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：您必须添加以下导入：

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


要单击按钮A，然后单击按钮B和C，依此类推，您必须引导WebDriverWait使

：

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"))))):
