selenium.common.exceptions.TimeoutException：当我尝试使用 python 单击按钮时会出现此错误

Question

我正在使用 Selenium 包来点击网站按钮。当我尝试时出现错误：

selenium.common.exceptions.TimeoutException: Message:

这是试图运行的代码。

import time 
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 
from bs4 import BeautifulSoup as BSoup
from datetime import date, timedelta
import pyodbc 
import datetime

browser =  webdriver.Firefox()
browser.get("https://www.cbsl.gov.lk/rates-and-indicators/exchange-rates/daily-buy-and-sell-exchange-rates")
#time.sleep(10)

#browser.find_element_by_xpath('//*[@id="dailyexchange"]/div[2]/div/button[1]').click()

wait = WebDriverWait(browser, 20)
element = wait.until(EC.element_to_be_clickable((By.XPATH, '//*[@id="dailyexchange"]/div[2]/div/button[1]')))
element.click()

Answer 1

您需要在点击按钮之前切换到 iframe：

browser.get("https://www.cbsl.gov.lk/rates-and-indicators/exchange-rates/daily-buy-and-sell-exchange-rates")
wait = WebDriverWait(browser, 20)
wait.until(EC.frame_to_be_available_and_switch_to_it('iFrameResizer2'))
element = wait.until(EC.element_to_be_clickable((By.NAME, 'select_button')))
element.location_once_scrolled_into_view
element.click()

Answer 2

所需元素在 <iframe> 中，因此您必须：

诱导 WebDriverWait 以获得所需的 框架并切换到它。
诱导 WebDriverWait 使所需的 元素可点击。

您可以使用以下任一解决方案：

使用CSS_SELECTOR:

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

options = Options()
options.add_argument("start-maximized")
browser = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
browser.get("https://www.cbsl.gov.lk/rates-and-indicators/exchange-rates/daily-buy-and-sell-exchange-rates")
WebDriverWait(browser, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe#iFrameResizer2[src='/cbsl_custom/exratestt/exratestt.php']")))
WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.btn.btn-default[name='select_button']"))).click()
