Selenium点击但不选择

Question

我正在制作一个在Khan Academy上运行的自动网络刮刀，使用selenium和python scraper进行离线备份（稍后会发布）。我正在努力让它回答问题（对错是无关紧要的）继续练习。不幸的是，selenium的.click（）函数实际上并没有选择答案。我认为这与指向错误的对象有关但我无法分辨。它目前突出显示该选项，但不选择它。

HTML for a single option (out of 4)

我制作了一些代码来重现错误，并将其连接到测试帐户以满足您的所有调试需求。感谢。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()

# gets us to the SAT Math Exercise page
driver.get('https://www.khanacademy.org/mission/sat/tasks/5505307403747328')

# these next lines just automate logging in. Nothing special.
login = driver.find_element_by_name('identifier')
login.send_keys('stackflowtest') # look, I made a new account just for you guys
passw = driver.find_element_by_name('password')
passw.send_keys('stackoverflow')
button = driver.find_elements_by_xpath("//*[contains(text(), 'Sign in')]")
button[1].click()

driver.implicitly_wait(5) # wait for things to become visible
radio = driver.find_element_by_class_name('perseus-radio-option')
radio.click()
check = driver.find_element_by_xpath("//*[contains(text(), 'Check answer')]")
check.click()

Answer 1

经过反复试验，我发现实际的点击选择可以通过指向带有类＆＃34;描述＆＃34;

的元素来完成。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()

# gets us to the SAT Math Exercise page
driver.get('https://www.khanacademy.org/mission/sat/tasks/5505307403747328')

# these next lines just automate logging in. Nothing special.
login = driver.find_element_by_name('identifier')
login.send_keys('stackflowtest') # look, I made a new account just for you guys
passw = driver.find_element_by_name('password')
passw.send_keys('stackoverflow')
button = driver.find_elements_by_xpath("//*[contains(text(), 'Sign in')]")
button[1].click()

driver.implicitly_wait(5) # wait for things to become visible
radio = driver.find_element_by_class_name('description')
radio.click()
check = driver.find_element_by_xpath("//*[contains(text(), 'Check answer')]")
check.click()

对于处理类似问题的人，我建议点击空间的边缘，让您选择并检查那里的元素。这可以防止您意外使用其中一个最里面的标签。
