不能单击按钮或使用硒提交表单

我正在尝试使用带Python的Selenium,单击在补习站点上发布的问题的答案,以便我可以通过命令行进行测试。

我输入以下内容:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver.get('https://www.varsitytutors.com/sat_critical_reading_diagnostic_1-problem-10821')

(这时会出现一个烦人的弹出窗口-我们现在可以忽略它)

页面上的答案嵌入如下形式:

         <div class="question_row">    
            <form class="button_to" method="post" action="/problem_question_answers/save_answer?answer_id=539461&amp;problem_id=5065&amp;qotd=false&amp;question_id=10821">
            <input id="answer_539461" class="test_button" type="submit" value="select" /><input type="hidden" name="authenticity_token" value="LE4B973DghoAF6Ja2qJUPIajNXhPRjy6fCDeELqemIl5vEuvxhHUbkbWeDeLHvBMtEUVIr7okC8Njp4eMIuU3Q==" /></form>
            <div class="answer">
              <p>English dramatists refused to employ slang in their work.</p>
            </div>
            <div style="clear:both"></div>
          </div>

我的目标是单击这样的答案,以便使用Selenium进入下一个问题。

我认为这样做可能很容易:

answer_buttons=driver.find_elements_by_class_name('test_button')
answer_buttons[1].click()

但是我收到错误消息,提示该元素不在驱动程序框架之内。

我也尝试过提交表单,但不会产生错误消息:

answer_forms=driver.find_elements_by_class_name('button_to')
answer_forms[1].submit()

但是它重定向到另一个不加载的URL: http://www.varsitytutors.com/sat_critical_reading_diagnostic_1-problems-results-d9399f1a-4e00-42a0-8867-91b1c8c9057d

是否可以通过编程方式进行此操作,还是网站的代码可以阻止这种情况发生?

编辑:

在一些帮助下,我最初可以单击一次按钮。但是下一个问题的相同提交按钮(通过xpath)仍然不可单击。这是我目前使用的代码:

driver.get('https://www.varsitytutors.com/practice-tests')

# click subject
subject=driver.find_element_by_xpath('/html/body/div[3]/div[9]/div/div[2]/div[1]/div[1]')
WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'/html/body/div[3]/div[9]/div/div[2]/div[1]/div[1]')))
subject.click()
# select specialty
specialty=driver.find_element_by_xpath('/html/body/div[3]/div[9]/div/div[2]/div[2]/div[1]/div[2]/a[4]')
WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'/html/body/div[3]/div[9]/div/div[2]/div[2]/div[1]/div[2]/a[4]')))
specialty.click()
# select test 
taketest=WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,'/html/body/div[3]/div[8]/div[3]/div[1]/div[1]/a[1]')))
driver.execute_script("arguments[0].click();", taketest)    

# click away popup
button=WebDriverWait(driver,5).until(EC.element_to_be_clickable((By.XPATH,"//button[contains(.,'No Thanks')]")))
button.location_once_scrolled_into_view
button.click()

# select first choice
choice=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,'/html/body/div[3]/div[7]/div[1]/div[3]/div[1]/form/input[1]')))
driver.execute_script("arguments[0].click();", choice)    

我在接下来的几行中再次重复此代码。但是,它无效。驱动器停留在第二个问题上,接下来的几下单击不起作用...

choice=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,'/html/body/div[3]/div[7]/div[1]/div[3]/div[1]/form/input[1]')))
driver.execute_script("arguments[0].click();", choice)
choice=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,'/html/body/div[3]/div[7]/div[1]/div[3]/div[1]/form/input[1]')))

driver.execute_script(“ arguments [0] .click();”,选择)

答案 0 :(得分:1)

尝试以下代码。它将处理弹出窗口,然后单击选择按钮。

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium import webdriver
driver=webdriver.Chrome()
driver.get('https://www.varsitytutors.com/sat_critical_reading_diagnostic_1-problem-10821')
driver.maximize_window()
button=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,"//button[contains(.,'No Thanks, Start The Test')]")))
button.location_once_scrolled_into_view
button.click()
eleQuestions=WebDriverWait(driver,10).until(EC.presence_of_all_elements_located((By.CSS_SELECTOR,'input.test_button')))
driver.execute_script("arguments[0].click();", eleQuestions[2])

button=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,"//button[contains(.,'No Thanks')]")))
button.location_once_scrolled_into_view
button.click()

请注意:您可以将索引从2更改为6。

如果您要选择提到的任何特定问题,请尝试以下代码。

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium import webdriver
driver=webdriver.Chrome()
driver.get('https://www.varsitytutors.com/sat_critical_reading_diagnostic_1-problem-10821')
driver.maximize_window()
button=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,"//button[contains(.,'No Thanks, Start The Test')]")))
button.location_once_scrolled_into_view
button.click()
eleQuestions=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,"//div[./p[text()='English dramatists refused to employ slang in their work.']]/parent::div//input[1]")))
driver.execute_script("arguments[0].click();", eleQuestions)

button=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,"//button[contains(.,'No Thanks')]")))
button.location_once_scrolled_into_view
button.click()
