如何通过Selenium和Python在Gas Day输入框中输入日期

我正在使用python和selenium读取此URL: http://ips.alliance-pipeline.com/Ips/MainPage.aspx?siteId=4

我用硒打开它,点击加号(左手边),然后点击“每日吞吐量”。打开一个带有“加油日”输入框的页面,我想在其中输入一个日期。如果这些步骤是在常规的Chrome浏览器中手动完成的,那么它可以正常工作,我可以输入日期,然后单击“检索”并获取数据表。但出于某种原因,Selenium使输入框为只读。我已经尝试删除“只读”属性(请参见注释掉的行),在这种情况下,该属性似乎被删除,但日期仍不在框中输入,数据也不被检索。

为什么硒使这个元素成为只读的,我怎样才能防止这种情况发生?

代码如下:

url = 'http://ips.alliance-pipeline.com/Ips/MainPage.aspx?siteId=4'
browser = webdriver.Chrome()
browser.get(url)
browser.find_element_by_id('treeviewn0').click() # click on "Capacity" heading
browser.find_element_by_id('treeviewt1').click() # click on "Daily Throughput" heading
time.sleep(2)
# browser.execute_script('document.getElementsByClassName("igte_EditInContainer")[0].removeAttribute("readonly")')
d = datetime.date.today() - datetime.timedelta(days=5)
d_str = d.strftime('%m/%d/%Y')
date_box = browser.find_element_by_xpath('//*[@id="MainContent_dtJobSchedForGrid"]/tbody/tr/td[1]/input')
# print(date_box.get_attribute('readonly'))
date_box.send_keys(d_str + '\n')
time.sleep(5)
browser.find_element_by_id('MainContent_btnRetrieveJobSchedForGrid').click() # click the Retrieve button
time.sleep(5)
