如何使用 Selenium 从网站上的日期选择器中处理和选择元素？

Question

我在 Selenium 中遇到问题，无法通过从网站上的日期选择器中选择特定日期来抓取我想要的数据。但是，我尝试的以下代码（例如，我选择 2019 年 4 月 11 日）只能生成最新日期（2019 年 4 月 24 日）的数据。如何才能访问我想要的日期？

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
from selenium.common.exceptions import NoSuchElementException
from selenium.common.exceptions import WebDriverException
from selenium.webdriver.common.action_chains import ActionChains

options = Options()
options.add_argument("--headless")
driver = webdriver.Chrome('chromedriver.exe', options=options)
driver.set_window_size(1024, 768)
actions = ActionChains(driver)
ticker = '00001'

y = '2019'
m = '4'
d = '11'

year_list = {'2018':'//*[@id="date-picker"]/div[1]/b[1]/ul/li[1]/button', '2019':'//*[@id="date-picker"]/div[1]/b[1]/ul/li[2]/button'}
month_list = {'1':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[1]/button', '2':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[2]/button', '3':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[3]/button', '4':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[4]/button', '5':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[5]/button', '6':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[6]/button', '7':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[7]/button', '8':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[8]/button', '9':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[9]/button', '10':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[10]/button', '11':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[11]/button', '12':'//*[@id="date-picker"]/div[1]/b[2]/ul/li[12]/button'}

Answer 1

您可以使用 javascript 设置值。

试试这个：

driver.execute_script("document.getElementById('txtShareholdingDate').value='2019/4/11'")
