问题描述

为什么通过硒切换为警报不稳定?

Why switching to alert through selenium is not stable?

例如.
1.运行代码，一切顺利.一切顺利. 但是，如果这段代码在几分钟内运行，则可能会出现错误. 例如，没有元素可以单击.依此类推.
2.在一个站点上，有一个警报窗口.

For example.
1. Run a code and all good. Everything worked out well. But if this code is run in a few minutes, then there may be errors. There is no element you can click on, for example. And so on.
2. On one site there is an alert window.

alert = driver.switch_to_alert()
alert.dismiss()

所以我将其关闭.但是他一直在工作.一切都好，然后是错误.

So I close it. But he works through time. All is well, then errors.

for al in range(3):
    try:
        alert = driver.switch_to_alert()
        alert.dismiss()
        time.sleep(randint(1, 3))
    except:
        pass

我写了所有内容，一切正常.
但是我认为这并不漂亮.
为什么一切都这么不稳定?
非常感谢.

I wrote and everything works out as it should.
But I think that this is not beautiful.
Why is everything so unstable?
Thank you very much.

推荐答案

根据您的代码块，您需要解决以下两个问题:

As per your code block there are a couple of issues which you need to address as follows :

• Switching to an Alert : The method switch_to_alert() is Deprecated and you should be using switch_to.alert instead. The API Docs clearly mentions the following :

 def switch_to_alert(self):
     """ Deprecated use driver.switch_to.alert
     """
     warnings.warn("use driver.switch_to.alert instead", DeprecationWarning)
     return self._switch_to.alert

Wait for the Alert to be present : You should always induce WebDriverWait for the Alert to be present before invoking accept() or dismiss() as follows :

WebDriverWait(driver, 5).until(EC.alert_is_present).dismiss()
