問題描述

我無法單擊此按鈕在我的機(jī)器人上創(chuàng)建結(jié)帳.我想點(diǎn)擊圖片獲取另一個(gè)頁面.

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>

這是我的代碼:

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

我收到此錯(cuò)誤:

推薦答案

在我的機(jī)器人上創(chuàng)建結(jié)帳的按鈕 似乎是一個(gè) 信用卡 相關(guān)領(lǐng)域，并且在歷史上信用卡相關(guān)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關(guān)討論:

You can find a couple of relevant discussions in:

• 無法定位使用 selenium python 的信用卡號元素
• org.openqa.selenium.NoSuchElementException:嘗試通過 CssSelector 定位 card-fields-iframe 時(shí)返回的節(jié)點(diǎn)(null)不是 DOM 元素

因此，如果所需的元素在 <iframe> 內(nèi)，那么您必須:

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

• 誘導(dǎo) WebDriverWait 使所需的框架可用并切換到它.
• 誘導(dǎo) WebDriverWait 使所需的元素可點(diǎn)擊.

• 您可以使用以下任一解決方案:

• 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()

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

注意:您必須添加以下導(dǎo)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
