问题描述
我无法单击此按钮在我的机器人上创建结帐.我想点击图片获取另一个页面.
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
在我的机器人上创建结帐的按钮 似乎是一个 信用卡 相关领域,并且在历史上信用卡相关字段位于<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讨论:
You can find a couple of relevant discussions in:
- 无法定位使用 selenium python 的信用卡号元素
- org.openqa.selenium.NoSuchElementException:尝试通过 CssSelector 定位 card-fields-iframe 时返回的节点(null)不是 DOM 元素
因此,如果所需的元素在 <iframe>
内,那么您必须:
So if the the desired element is within an <iframe>
so you have to:
- 诱导 WebDriverWait 使所需的框架可用并切换到它.
- 诱导 WebDriverWait 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
