以前我问过如何点击页面上的按钮。它第一次工作，但我意识到，有时它有时它不起作用。问题是我有多个页面，有时我得到一些页面的数字，但对于一些我什么也得不到。有没有办法获得我需要的所有数据？ Project是我在Python的这个初学者课程的期末考试。
需要单击的按钮位于页面的右上方，并显示文本“Prikažibloj”。这是我的尝试，但它不能按我的意愿工作：
condos = [

condo_agency_home_phones = []
condo_agency_cell_phones = []
options = Options()
options.headless = False
driver = webdriver.Chrome('/Users/Nenad/chromedriver', options=options)
for condo in condos:
driver.get(condo)
try:
element = driver.find_element_by_css_selector('body > div:nth-child(14) > div.row.pt-4 > div.col-lg-4.mb-5 > div.border-box.pt-3.pl-3.pr-3.pb-0.d-none.d-lg-block > div > div.row > div.col-12.col-sm-6.contact-footer > div > div > form:nth-child(2) > button').click()
sleep(randint(3, 5))
element2 = driver.find_element_by_css_selector('body > div:nth-child(14) > div.row.pt-4 > div.col-lg-4.mb-5 > div.border-box.pt-3.pl-3.pr-3.pb-0.d-none.d-lg-block > div > div.row > div.col-12.col-sm-6.contact-footer > div > div > form:nth-child(4) > button').click()

condo_agency_home_phones.append(home_phone.text)
condo_agency_cell_phones.append(cell_phone.text)
except:
condo_agency_home_phones.append('NaN')
condo_agency_cell_phones.append('NaN')
我得到的解决方案是：
element = driver.find_element_by_css_selector('button[type="button"]').click()
有时这点击按钮，我仍然不知道如何在点击后提取数字。如果有人知道该怎么做，请告诉我。
使用WebDriverWait来处理动态元素。但是你需要给它一些时间。单击按钮后得到整个电话号码。睡眠（1）。
condo_agency_home_phones = []
condo_agency_cell_phones = []
for condo in condos:
driver.get(condo)
try:
wait=WebDriverWait(driver,10)
element =wait.until(expected_conditions.element_to_be_clickable((By.XPATH,"//button[contains(text(),'broj')]")))
element.click()
time.sleep(1)
home_phone=wait.until(expected_conditions.element_to_be_clickable((By.XPATH,"(//span[@class='cell-number'])[1]")))
condo_agency_home_phones.append(home_phone.text)
wait1 = WebDriverWait(driver, 10)
element2 =wait1.until(expected_conditions.element_to_be_clickable((By.XPATH,"//button[contains(text(),'broj')]")))
element2.click()
time.sleep(1)
wait2 = WebDriverWait(driver, 10)
cell_phone=wait2.until(expected_conditions.element_to_be_clickable((By.XPATH,"(//span[@class='cell-number'])[2]")))
condo_agency_cell_phones.append(cell_phone.text)
except:
condo_agency_home_phones.append('NaN')
condo_agency_cell_phones.append('NaN')
print(condo_agency_home_phones,condo_agency_cell_phones)
请注意，您需要使用以下导入。
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions
from selenium import webdriver
import time
欢迎来到SO。以下是选项。
选项1：使用预期条件（通过这种方式，您确保在单击之前找到元素）
wait = WebDriverWait(self.driver, 10)
ele = wait.until(EC.presence_of_element_located((By.XPATH, "//button[.='Prikaži broj']")))
ele.click
选项2：使用Javascript。 （这就像在按钮上发送点击事件一样）
ele = driver.find_element_by_xpath("//button[.='Prikaži broj']")
driver.execute_script("arguments[0].click();",ele);
您也可以考虑尝试等待可点击
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "form button[type=button]"))).click()
额外进口：
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
以下代码涉及Adblock，随之而来的是大部分时间所有数字：
path_to_extension = r'C:\Users\Nenad\Desktop\3.42.0_0'
options = Options()
options.add_argument('load-extension=' + path_to_extension)
options.headless = False
driver = webdriver.Chrome('/Users/Nenad/chromedriver', options=options)
driver.create_options()
扩展路径从以下位置复制：
C：\ Users \ Nenad \ AppData \ Local \ Google \ Chrome \ User Data \ Default \ Extensions \ gighmmpiobklfepjocnamgkkbiglidom
我认为这是有效的解决方案。
