python - 使用 Firefox WebDriver 单击与同名标签耦合的单选按钮

Question

我在 Fedora 29 上使用 Selenium 3.12.0、Python 3.7.2 和 Firefox 66.0.1。我在单击单选按钮时遇到问题。单选按钮位于标签内，并且单选按钮和标签使用相同的名称。页面位于https://complaints.donotcall.gov/complaint/complaintcheck.aspx .

<label for="PrerecordMessageYESRadioButton">
    <input id="PrerecordMessageYESRadioButton" type="radio" name="PrerecMsg" value="PrerecordMessageYESRadioButton" tabindex="7">
    <label for="PrerecordMessageYESRadioButton">Yes</label>
</label>

当我在页面完成后检查屏幕截图时，我发现单选按钮未被单击。页面上的其他元素都已完成。

我尝试过 driver.find_element_by_id("PrerecordMessageYESRadioButton")、driver.find_element_by_name("PrerecMsg") 和 driver.find_element_by_css_selector("input#PrerecordMessageYESRadioButton “)。选择后，我还尝试了 radio.click()、radio.send_keys(Keys.ENTER) 和 radio.send_keys(Keys.SPACE) 没有喜悦。最后，driver.execute_script("arguments[0].click();", radio) 也没有帮助。

在这种情况下，如何单击与标签耦合的单选按钮？

单选按钮似乎会造成相当多的麻烦。这里有一些相关的问题，但它们对解决这个问题没有帮助。第一个引用文献和 @yong 的回答似乎与这个问题非常相关。

这是测试脚本:

$ cat test-driver.py
#!/usr/bin/env python3

import time
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.options import Options

def main():

    opts = Options()
    opts.headless = True
    driver = webdriver.Firefox(options=opts)   

    #################################################

    print("Fetching page 1")    
    driver.get("https://complaints.donotcall.gov/complaint/complaintcheck.aspx")

    print("Clicking Continue")
    button_continue = driver.find_element_by_id("ContinueButton")
    button_continue.click()

    #################################################

    print("Fetching page 2")    
    time.sleep(2) 

    text_phone = driver.find_element_by_id("PhoneTextBox")
    for ch in "8005551212":
        text_phone.send_keys(ch)

    text_calendar = driver.find_element_by_id("DateOfCallTextBox")
    for ch in "03/30/2019":
        text_calendar.send_keys(ch)

    dropdown_hour = driver.find_element_by_id("TimeOfCallDropDownList")
    dropdown_hour.send_keys("10")

    dropdown_minute = driver.find_element_by_id("ddlMinutes")
    dropdown_minute.send_keys("30")

    # PrerecordMessageYESRadioButton
    radio_robocall = driver.find_element_by_name("PrerecMsg")
    # radio_robocall = driver.find_element_by_css_selector("input#PrerecordMessageYESRadioButton")
    radio_robocall.send_keys(Keys.ENTER)
    radio_robocall.send_keys(Keys.SPACE)
    ...

    driver.quit()


if __name__ == "__main__":
    main()

通过id枚举页面上的元素:

ids = driver.find_elements_by_xpath('//*[@id]')
for val in ids:
    print(val.get_attribute('id'))

返回以下内容:

Head1
_fed_an_ua_tag

topnav
navbtn
mobileChangeLang

__EVENTARGUMENT
__VIEWSTATE

这是我在获取屏幕截图后看到的内容。

请使用is_selected检查 radio 状态:

radio_robocall = driver.find_element_by_name("PrerecMsg")
# is_selected should return False
print(f"radio_robocall status: {str(radio_robocall.is_selected())}")

radio_robocall.click()
# is_selected should return True
print(f"radio_robocall status: {str(radio_robocall.is_selected())}")
