Python单击警报上的按钮[英] Python click button on alert

正确查找并单击"接受"输入按钮.单击"接受"后,将打开JavaScript警报(OK/CANCEL)以确认验收.但是,脚本找不到结果警报.或者,至少它无法接受它,因为称为异常.

正如您所看到的,我试图switch_to().alert(),但这不起作用.

我做错了什么?非常感谢您的帮助,我一直在努力工作时间.

更新

此代码在虚拟服务器上运行,不使用UI.我刚才意识到司机是幻影,而不是Chrome.所以,这可能是它失败的原因.我更新了这个问题来反映这一点.

我已经尝试了类似问题的建议,但它不起作用.第三方网站要求警报确认完成此过程,但我的脚本无法看到它,因为它是无头的.

推荐答案

这里的几个点:

  • switch_to_alert 已被弃用,因此我们必须强制使用 switch_to().alert()
  • 在我看来纯粹的时间问题.因此,我们需要诱导 ExplicitWait WebDriverWait ,其中 expected_conditions 子句设置为 alert_is_present 如下:

    from selenium.webdriver.support import expected_conditions as EC
    #code block
    self.chrome_session.find_element_by_xpath("//input[@value='Accept']").click()
    WebDriverWait(self.chrome_session, 10).until(EC.alert_is_present)
    self.chrome_session.switch_to().alert().accept()
    print("Accepted work order {0} at {1}.".format(link_text, datetime.datetime.now()))
    

其他推荐答案

我不知道以下代码是否有帮助您,在一个点,我面临同样的问题并最终等待警报然后接受警报,为我工作.

from selenium.common.exceptions import NoAlertPresentException,

   def wait_for_alert(self):

        for i in range(50):
            try:
                alert = chrome_session.switch_to.alert
                if alert.text:
                   break
            except NoAlertPresentException:
              pass
            time.sleep(.25)
        else:
            raise NoAlertPresentException("Alert visibility timed out")
    return alert

wait_for_alert().accept()

其他推荐答案

在下面尝试代码!为我工作!

alert = driver.switch_to.alert #This .alert will work For Python
try:
   alert.accept() #If you want to Accept the Alert
except:
   alert.dismiss()  #If  You want to Dismiss the Alert.
