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
