Python+Selenium超时异常

Question

这是我第一次使用Python和Selenium。代码的第一部分可以工作，但当它转到第二页时，它永远找不到任何元素。如果我翻转代码，让它先转到第二个网站，它就可以工作了。我在这里做错了什么？我试过xpath，CSS_Selector，Class_Name似乎什么都不起作用。这是我得到的错误：

提前感谢！

Answer 1

您必须将驱动程序切换到新打开的选项卡。
否则，焦点将保持在第一个浏览器窗口上
TimeoutException实际上意味着Selenium无法通过传递的定位器定位元素
此外，您正在使用的定位器也不好
试试这个：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.common.action_chains import ActionChains
import time
driver = webdriver.Chrome ("C:/chromedriver.exe")
driver.get("https://10minutesemail.net/")
Copy_Email = WebDriverWait(driver, 20).until(
EC.presence_of_element_located((By.ID, "copyEmailAddress"))).click()
time.sleep(10)
driver.execute_script("window.open('https://quora.com/','_blank')")
driver.switch_to.window(driver.window_handles[1])
click_Register = WebDriverWait(driver, 20).until(
EC.presence_of_element_located((By.CLASS_NAME, "q-text qu-ellipsis qu-whiteSpace--nowrap"))).click()
name = driver.find_element(By.NAME, "profile-name")
email = driver.find_element(By.ID, "email")
name.send_keys("Jackson Fuller")
