Python - no such alert

python selenium中关闭网页弹出窗口用到了

driver.switch_to.alert.accept()

但是运行时报错：no such alert

解决方案:增加等待弹窗弹出时间，可以使用显式等待，当页面完全加载出弹出窗元素后再操作accept()

from selenium.webdriver.support import expected_conditions as EC

from selenium.webdriver.support.wait import WebDriverWait

WebDriverWait(driver,20,0.5).until(EC.alert_is_present())

actual_alert=driver.switch_to.alert.text
