NoSuchElementException:消息:尝试通过Selenium和Python单击按钮VISA时无法找到元素 [英] NoSuchElementException: Message: Unable to locate element while trying to click on the button VISA through Selenium and Python

问题描述

我无法点击此按钮在我的漫游器上创建结帐. 我想单击该图像以获取另一个页面.

I can't click on this button to create a checkout on my bot. I want to click the image to get another page.

<label for="VISA" class="choiceLabel">
            
				<input type="radio" class="visuallyhidden" name="cardTypeRadio" id="VISA" value="VISA" title="VISA" onclick="validateAndSubmit('VISA');">
					<span class="imgElt xh-highlight" onclick="validateAndSubmit('VISA');">
              	<img src="/static/2.15.0.1/images/type-carte/visa.png" alt="VISA" title="Visa">
            	</span>
            <span class="txtElt">Visa</span>
          </label>

这是我的代码:

try:
             check = WebDriverWait(driver, delay).until(EC.presence_of_element_located((By.ID,"VISA" )))
            
             print ("Page is ready!")
             visa = driver.find_elements_by_xpath("label[@class='choiceLabel'][4]")
             visa.click()


        except TimeoutException:
             print ("Loading took too much time!")
             return check

我收到此错误:

推荐答案

在我的漫游器上创建结帐的按钮似乎是与信用卡相关的字段， 信用卡的相关字段位于<iframe>中.

The button to create a checkout on my bot seems to be a Credit Card related field and historically Credit Card related fields resides within <iframe>.

您可以在以下位置找到一些相关的讨论:

You can find a couple of relevant discussions in:

• 无法找到使用硒python的信用卡号的元素
• org .openqa.selenium.NoSuchElementException:尝试通过CssSelector定位card-fields-iframe时，返回的节点(空)不是DOM元素

• Unable to locate element of credit card number using selenium python
• org.openqa.selenium.NoSuchElementException: Returned node (null) was not a DOM element when trying to locate card-fields-iframe by CssSelector

因此，如果所需元素在<iframe>内，则必须:

So if the the desired element is within an <iframe> so you have to:

• 诱导 WebDriverWait 以使所需的框架可用并切换到.
• 诱导 WebDriverWait 以使所需的元素可点击.

• 您可以使用以下任一解决方案:

• Induce WebDriverWait for the desired frame to be available and switch to it.
• Induce WebDriverWait for the desired element to be clickable.

• You can use either of the following solutions:

• 使用CSS_SELECTOR:

WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe_css_selector")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "label[for='VISA']"))).click()

使用XPATH:

WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe_xpath")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//label[@for='VISA']"))).click()

注意:您必须添加以下导入:

Note : You have to add the following imports :

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