selenium——更改页面元素，让不能输入的框体变成可以输入

直接上代码吧

import unittest
import time
from selenium import webdriver


def addAttribute(driver, elementJSPath, attributeName, value):
    jsScript = "document.querySelector('{0}').{1} = '{2}'".format(
        elementJSPath, attributeName, value)
    driver.execute_script(jsScript)


def setAttribute(driver, elementJSPath, attributeName, value):
    jsScript = "document.querySelector('{0}').setAttribute('{1}', '{2}')".format(
        elementJSPath, attributeName, value)
    driver.execute_script(jsScript)


def removeAttribute(driver, elementJSPath, attributeName):
    jsScript = "document.querySelector('{0}').removeAttribute('{1}')".format(
        elementJSPath, attributeName)
    driver.execute_script(jsScript)


class TestDemo(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()

    def test_dateChange(self):
        url = "https://www.12306.cn/index/"
        self.driver.get(url)
        time.sleep(5)
        elementJS = '#train_date'
        removeAttribute(self.driver, elementJS, 'readonly')
        element = self.driver.find_element_by_xpath('//*[@id="train_date"]')
        element.clear()
        element.send_keys('fuck it')
        print(element.get_attribute('value'))

    def tearDown(self):
        time.sleep(3)
        self.driver.quit()


if __name__ == "__main__":
    unittest.main()
