硒找不到元素，但是元素在https://login.aliexpress.com/网页上 [英] Selenium can't find element, but element is on the https://login.aliexpress.com/ webpage

问题描述

在网站上，硒脚本无法找到登录名和密码字段.我试图通过xpath，css选择器，名称和类名称进行搜索.但没有任何效果.

On the website the selenium script cannot find the login and password fields. I tried to search by xpath, css selector, name and class name. But nothing worked.

from selenium import webdriver
from time import sleep
driver = webdriver.Firefox() 
driver.get("https://login.aliexpress.com/")
driver.find_element_by_id("fm-login-id").send_keys("test_id")
driver.find_element_by_id("fm-login-password").clear()
driver.find_element_by_id("fm-login-password").send_keys("test_pass")
driver.find_element_by_id("fm-login-submit").click()`

我试图在Selenium IDE的帮助下做到这一点，并且一切都在GUI中工作.但是在我将代码导出到python并运行它之后，程序给出了一个错误，即找不到该元素.

I tried to do this with the help of Selenium IDE, and everything worked in the GUI. But after I exported the code to python and ran it, the program gave an error that it could not find the element.

推荐答案

但是，所需的元素在<iframe>中，因此您必须:

However as the the desired elements are 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.

• 您可以使用以下解决方案:

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

• You can use the following solution:

• 使用CSS_SELECTOR:

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

driver = webdriver.Firefox(executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get("https://login.aliexpress.com/")
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe#alibaba-login-box[src^='https://passport.aliexpress.com/mini_login.htm?']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.fm-text#fm-login-id"))).send_keys("test_id")
driver.find_element_by_css_selector("input.fm-text#fm-login-password").send_keys("test_pass")
driver.find_element_by_css_selector("input.fm-button#fm-login-submit").click()

临时浏览快照:

• 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

您可以在

• 在iframe下处理#document的方式
