How to use selenium to handle and select elements from the date picker on the website?

Question

I have a problem in selenium to scrap the data that i want by selecting the specific date from the date picker on the website. However, the code below I tried (eg i pick 11 April 2019) could only generate the data on the latest date (24 April 2019). Is there any way to make it work to access the date that i want?

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

You could set the value using javascript.

Try this:

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