Question

我正在使用 Selenium 包来单击网站的按钮。当我尝试时，出现错误:

selenium.common.exceptions.TimeoutException: Message:

这是尝试运行的代码。

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

点击按钮之前需要切换到 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()
