UnhandledAlertException：意外警报打开：{警报文本：保存成功。}

Question

我在Selenium中处理Chrome驱动程序弹出的警告时遇到了以下错误。

Exception in thread "main" org.openqa.selenium.UnhandledAlertException: unexpected alert open: {Alert text : Save successfully.}

场景：

当两个警报立即出现时，就会发生这种情况。

出现第一个警报弹出窗口，我正在处理它：

Alert alertf = driver.switchTo().alert();
alertf.accept();

立即出现下一个警报，我使用了等待，然后实施了另一个警报

Alert alert2 = driver.switchTo().alert();
alert2.accept();

但这失败了。

执行在第一个警报时停止。

完全错误:

如果忽略警报不会影响您的场景，您可以简单地使用ovverride警报方法，通过在警报之前执行javascript代码来克服此问题，这正是导致错误的原因：

window.alert = function() {};
