如何通过 Python 使用 Selenium 将日期作为文本直接发送到具有只读属性的日历控件? [英] How to send a date directly as text to a calendar control with readonly attribute using Selenium through Python?

问题描述

我正在尝试使用 python 和 selenium 从日历中选择一个日期，但我需要一些帮助，我在 VBA 中执行此操作，但我想在 python 中执行此操作.提前致谢.

I'm trying to select a date form a calendar with python and selenium but I need some help, I did this in VBA but I want to do this in python. Thanks in advance.

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

driver=webdriver.Firefox(executable_path=r'..geckodriver.exe')
driver.get('https://burghquayregistrationoffice.inis.gov.ie/Website/AMSREG/AMSRegWeb.nsf/AppSelect?OpenForm')    

# this is the problem
driver.find_element_by_id('GNIBExDT').send_keys(10/08/2019)

推荐答案

这是一个只读输入 - 如果你查看 HTML src，它有 readonly 属性.这意味着 send_keys 正在尝试 键入你的价值，但不能，因为它是只读的.但是，您仍然可以手动设置 - 尝试:

It's a read-only input - if you look in the HTML src, it's got the readonly attribute. This means that send_keys, which works by emulating key presses as if it were a real user (to also trigger any eventlisteners listening for change in the input), is trying to type your value, but can't, since it's read-only. However, you can still set it manually - try:

driver.execute_script("document.getElementById('GNIBExDT').value = '10/08/2019'")

这会执行以下JS代码:

This executes the following JS code:

document.getElementById('GNIBExDT') // Equivalent of driver.find_element_by_id('GNIBExDT') in pure JS
    .value = // Used to set the 'value' of the input, which is what will be read on the backend when the form is submitted. This just sets the value directly, so it doesn't matter if it's read-only.
    '10/08/2019' // The date, in string form.

他们似乎只是在示例网站上使用基本字符串来表示日期，因为它是一个自定义日期选择器.因此，他们没有做任何特别的事情，例如使用实际的日期格式或 Date 对象.但是，由于根据标题，这是您想要的，我将举一个例子，让其他在谷歌上搜索过这个问题的人这样做:

It seems like they're just using basic strings on the example website to represent dates, since it's a custom datepicker. So, they're not doing anything special, such as using actual date formats or Date objects. However, since based on the title this is what you'd like, I'll give an example to do such for anyone else who's Googled this problem:

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

driver=webdriver.Firefox(executable_path=r'..geckodriver.exe')
driver.get('https://www.w3schools.com/html/tryit.asp?filename=tryhtml_input_date')

driver.execute_script("document.getElementsByTagName('input')[0]"  # Get the date picker from the DOM
                     +".valueAsDate"  # Set the value *as a date object* - this is only available in real date pickers (`<input type='date'>`)
                     +" = new Date('2020-03-11')"  # We therefore need to define it as a date object, which we do in 'yyyy-mm-dd hh:mm:ss GMT+hhmm' format
