先使用switch_to.alert切换到浏览器弹出框
再使用alert类的操作方法：
dismiss()：取消 accept()：确定 text()：获取弹框中的文本信息 send_keys()：往弹框中输入文本信息 js之：alerts弹框：import timefrom selenium import webdriverfrom selenium.webdriver.support.wait import WebDriverWaitfrom selenium.webdriver.support import expected_conditions as ECfrom selenium.webdriver.common.desired_capabilities import DesiredCapabilitiesdesired_capabilities = DesiredCapabilities.CHROMEdesired_capabilities[\'pageLoadStrategy\'] = \'normal\'driver = webdriver.Chrome()start_time = time.time()driver.get(\'https://www.selenium.dev/documentation/en/webdriver/js_alerts_prompts_and_/confirm/iations/\')end_time = time.time() - start_timeprint(end_time)driver.find_element_by_xpath("//a[contains(text(),\'See an example alert\')]").click()WebDriverWait(driver, 10).until(EC.alert_is_present())alert = driver.switch_to.alerttext_info = alert.textprint(text_info)alert.accept()time.sleep(10)driver.quit() 控制台显示了js弹框中的文本信息：

所以百度了一个能看到alert弹框返回值的栗子：
首先我在send_key()中输入的是 ” 自动化测试 ” 然后点击 ” 确定 ” ，页面显示的就是我输入的返回值：
