尝试登录具有 iframe 登录部分的网站？

Question

第一次遇到 iFrame 之类的。刚刚学习了 Python 的基础知识，并创建了一个类似的脚本来登录网站。但是，对于这个特定的网站，我无法通过 iframe？网站：https://www.trademe.co.nz我尝试过使用 ChatGPT，但目前还没有成功。

我进入登录页面并尝试了以下代码：

>     #importing modules.
from selenium import webdriver from selenium.webdriver.common.by import By
from selenium.common.exceptions
        > import NoSuchElementException import time from
        > selenium.webdriver.support.ui import WebDriverWait from
        > selenium.webdriver.support import expected_conditions as EC
        > 
        > #opening firefox and going to Google homepage. browser = webdriver.Firefox() browser.get('https://www.google.co.nz')
        > 
        > browser.get('https://www.google.co.nz')
        > 
        > #going to trademe.co.nz's website. search_elem = browser.find_element(By.CSS_SELECTOR, '#APjFqb') search_elem.click()
        > time.sleep(3) search_elem.send_keys('trademe.co.nz')
        > search_elem.submit() time.sleep(5) seek_elem =
        > browser.find_element(By.CSS_SELECTOR, 'h3.LC20lb.MBeuO.DKV0Md')
        > seek_elem.click()
        > #congratulations, you have gained access to seeks homepage website.
        > 
        > #signing into trademe.co.nz website. searchx_elem = browser.find_element(By.CSS_SELECTOR, '.tm-shell-main-nav__mtm-link')
        > searchx_elem.click()
        > ##iframe = browser.find_element(By.ID, 'tm-graffiti-iframe')
        > ##time.sleep(3)
        > ##browser.switch_to.frame(iframe)
        > ##time.sleep(3)
        > ##queryElement = browser.find_element(By.ID, 'Email')
        > ##time.sleep(3)
        > ##queryElement.send_keys('[email protected]')
        > ## try:
        >     # Wait up to 10 seconds for the element to load
        >     email_input = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.ID, 'Email')))
        >     email_input.send_keys("[email protected]") except:
        >     print("Couldn't locate the element")

Answer 1

您用注释标记覆盖的代码通常是正确的。尝试等待元素的存在，而不是立即与其交互。

使用 iFrame 元素时，您应该执行以下操作：

• 查找 iframe（确保您没有使用某些动态属性来定位框架）
• 使用“driver.switch_to.frame”（在您的情况下为 browser.switch_to.frame）切换到框架。您可以将框架名称、索引或定位元素传递给“框架”方法
• 开始寻找框架内的元素，执行所需的操作
• 通过“driver.switch_to.default_content()”切换回默认内容（跳出 iFrame）（在您的情况下为 browser.switch_to.default_content()）

不幸的是，我无法访问您提供的网站，但这里有一个示例，说明如何在 the-internet.herokuapp

上使用 iFrame 内部的元素

driver = webdriver.Firefox() 
driver.maximize_window()
wait = WebDriverWait(driver, 10)
actions = ActionChains(driver)

try:
    driver.get("https://the-internet.herokuapp.com/iframe")

    # find iframe and switch to it
    iframe = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, 'iframe.tox-edit-area__iframe')))
    driver.switch_to.frame(iframe)

    # now we are looking for the element inside the iframe
    ptag = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, 'body > p')))

    # do something with the located element
    print(ptag.text)
    ptag.send_keys("Writing some text to the <p> inside of the iframe")

    # go back to the 'root', i.e. leave the iframe
    driver.switch_to.default_content()

    # try to access the element inside the iframe when you are not in the iframe
    # THIS LINE WILL FAIL (!) BECAUSE WE ARE NOT IN THE IFRAME ANYMORE
    wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, 'body > p')))
finally:
    driver.quit()
