我做错了什么。硒植物素

Question

是因为我使用python REPL吗？我不知道那是什么

我的代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

PATH = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)

driver.get("https://member.lazada.com.my/user/login?spm=a2o4k.home.header.d5.1e532e7eD9UgkJ&redirect=https%3A%2F%2Fwww.lazada.com.my%2F%3Fspm%3Da2o4k.login_signup.header.dhome.7d0d49fbWgHyQw")
print(driver.title)

time.sleep(10)

driver.find_element_by_id("a2o4k.login_signup.menu.i0.128549fbdpzNIi").click()

错误代码：

Answer 1

您正试图找到一个动态的id，它将改变，而不是使用css选择器或xpath。我假设您正在尝试单击“注册”按钮或类似的按钮。下面是该元素的一个示例

CSS选择器

WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.mod-login-btn > button"))).click()

XPath

WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "button[text()='SIGN UP']"))).click()

进口

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