Unable to send date as text to datepicker field using send_keys when max attribute is set using ChromeDriver and Selenium

问题

I am trying to use chromedriver to download some files.

I have switched to chromedriver because in firefox the link I need to click opens a new window and the download dialog box appears even after all the required settings and I wasn't able to get around it.

chromedriver works fine for the download but I can't seem to send_keys() to the element below, it works on firefox but can't seem to get it to work on this.

<input name="" value="" id="was-returns-reconciliation-report-start-date" type="date" class="was-form-control was-input-date" data-defaultdate="" data-mindate="" data-maxdate="today" data-placeholder="Start Date" max="2020-02-12">

I have tried:

el = driver.find_element_by_id("was-returns-reconciliation-report-start-date")
el.clear()
el.send_keys("2020-02-01")
el.send_keys(Keys.ENTER)  # Separately

# Tried without clear as well
# no error but the date didn't change in the browser

driver.execute_script("document.getElementById('was-returns-reconciliation-report-start-date').value = '2020-01-05'")

# No error and no change in the page

To send a character sequence to an <input> field ideally you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies:

• Using ID:

  el = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.ID, "was-returns-reconciliation-report-start-date")))
  el.clear()
  el.send_keys("2020-02-12")
  

• Using CSS_SELECTOR:

  el = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "input.was-form-control.was-input-date#was-returns-reconciliation-report-start-date")))
  el.clear()
  el.send_keys("2020-02-12")
  

• Using XPATH:

  el = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//input[@class='was-form-control was-input-date' and @id='was-returns-reconciliation-report-start-date']")))
  el.clear()
  el.send_keys("2020-02-12")
  

• Note : You have to add the following imports :

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