点击框项选择 Selenium Python 不保留

Question

自动收集天气报告的脚本。 网页允许点击框选择额外的列（请参阅添加列下拉框）。 我似乎无法保留我的点击框选择。 （手动运行网站确实保存了我的选择）我尝试手动设置我的选择并保存/加载 cookies。我尝试使用 Selenium 单击每个点击框但选择没有保留。 否则，脚本运行但只显示天气数据列的基本数量

Answer 1

您需要正确使用WebDriverWait并正确定位 web 个元素。
此外，您永远不应在同一代码中混用implicitly_wait和WebDriverWait 。
以下代码打开“添加列”对话框并选中“露点”复选框。

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

options = Options()
options.add_argument("start-maximized")

webdriver_service = Service('C:\webdrivers\chromedriver.exe')
driver = webdriver.Chrome(options=options, service=webdriver_service)
wait = WebDriverWait(driver, 10)

url = "https://www.xcweather.co.uk/forecast/"
driver.get(url)

wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a[onclick*='Layout']"))).click()
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='dew']"))).click()

结果是
