将从一个日期选择器中选择的日期存储到下一个日期选择器中

Question

由于找不到current_date = calendar.find_element_by_class_name("ui-datepicker-days-cell-over") 的元素，我在尝试选择返回日期时遇到问题。对于出发日期，它可以工作，但不能返回日期。这是因为当您打开返回日期的日期选择器时，它会自动为您突出显示日期（这是元素），但对于返回日期，打开日期选择器时它没有突出显示日期（仅在您选择日期）。

所以我的问题是有人知道如何修复下面的代码，以便它能够检索从出发日期选择器中选择的日期（选择的日期是 next_available_date）并以某种方式将其存储在返回日期选择器中以便它成为返回日期选择器中的选定日期？

目前下面的代码能够从出发日期选择器检索下一个可用日期没有问题，问题只是返回日期选择器。 （两个代码块几乎是相互镜像的）

# select depart date
datepicker = driver.find_element_by_id("ctl00_centralDynamicContent_OutDateTextBox")
actions.move_to_element(datepicker).click().perform()

# find the calendar, month and year picker and the current date
calendar = driver.find_element_by_id("ui-datepicker-div")
month_picker = Select(calendar.find_element_by_class_name("ui-datepicker-month"))
year_picker = Select(calendar.find_element_by_class_name("ui-datepicker-year"))
current_date = calendar.find_element_by_class_name("ui-datepicker-days-cell-over")

# printing out current date
month = month_picker.first_selected_option.text
year = year_picker.first_selected_option.text
print("Current departure date: {day} {month} {year}".format(day=current_date.text, month=month, year=year))

# see if we have an available date in this month
try:
    next_available_date = current_date.find_element_by_xpath("following::td[@title='Click to see flights on this date' and ancestor::div/@id='ui-datepicker-div']")
    print("Found an available departure date: {day} {month} {year}".format(day=next_available_date.text, month=month, year=year))
    next_available_date.click()

因为我记得您正在使用的目标网站，所以这里有一个想法（未经测试）。

日期选择器将初始日期设置为“只读”日期输入中的内容。让我们移除 readonly 属性并将返回日期输入值设置为之前选择的出发日期：

from datetime import datetime

# get depart date
depart_date = datetime.strptime(" ".join([next_available_date.text, month, year]), "%d %b %Y")
initial_return_date = depart_date.strftime("%d-%m-%Y")

return_date_input = driver.find_element_by_id("ctl00_centralDynamicContent_OutDateTextBox")
# remove readonly attribute
driver.execute_script("arguments[0].removeAttribute('readonly','readonly');", return_date_input)
return_date_input.send_keys(initial_return_date)

# open datepicker

这是一个简单的示例（使用 jet2.com），其中返回日期输入值设置为选择的出发日期：
