我在处理来自 Chrome 的 ALert 弹出窗口时遇到问题，我不断收到以下错误。org.openqa.selenium.UnhandledAlertException：意外警报打开（会话信息：chrome=29.0.1547.66）（驱动程序信息：chromedriver=2.3，平台=Windows NT 5.1 SP3 x86）。
Here is what i have tried so far. WHen i get to the page where the error is displayed:
这是我迄今为止尝试过的。当我到达显示错误的页面时：
driver.switchTo().alert.accept();
Also tried.
也试过了。
Alert alert = driver.switchTo().alert();
alert.accept();

还有同样的错误。

It may be your ChromeDriver version. I wouldn't recommend always updating to the newest versions of something. Defects abound.
它可能是您的 ChromeDriver 版本。我不建议总是更新到最新版本的东西。缺陷比比皆是。
I'm using ChromeDriver win32_2.0 and it works fine. Try that version.
我正在使用 ChromeDriver win32_2.0，它工作正常。试试那个版本。

Actually it(UnhandledAlertException) comes if you don't handle alert properly Otherwise, If you do any operation with driver instance before closing the alert.
实际上它(UnhandledAlertException) 如果您没有正确处理警报就会出现，否则，如果您在关闭警报之前对驱动程序实例进行了任何操作。
Example
例子
Step-1: Click Button //this will lead to get an alert
步骤 1：单击按钮 //这将导致收到警报
Step-2: //Here you need to alert handle
Step-2: //这里你需要提醒句柄
In step-2 instead of handling alert if you do any other operation with driver instance it will throw UnhandledAlertException exception.
在第 2 步中，如果您对驱动程序实例执行任何其他操作，而不是处理警报，它将抛出 UnhandledAlertException 异常。

I got this problem with IE. But with two simple changes it started to work like under FF:
1)As suggested https://stackoverflow.com/a/20611297/2872258I set another option while creating IEDriver - unexpectedAlertBehaviour=Ignore
2)I had also WebDriverWait for Alert, with setting ImplicityWait to "0" at the very beginning - according what @Santoshsarma said it was another problem.
Might be a solution as well for Chrome.
我在 IE 上遇到了这个问题。但是通过两个简单的更改，它开始像在 FF 下一样工作：
1）按照https://stackoverflow.com/a/20611297/2872258 的建议，我在创建 IEDriver 时设置了另一个选项-unexpectedAlertBehaviour=Ignore
2）我也有 WebDriverWait for Alert，在一开始就将 ImplicityWait 设置为“0”-根据@Santoshsarma 所说，这是另一个问题。
也可能是 Chrome 的解决方案。

I tried catching the stackoverflow error and it worked for me as a workaround.
我尝试捕获 stackoverflow 错误，它作为一种解决方法对我有用。
try
{
driver.findElement(By.xpath('xpath')).click(); // command that will trigger the alert window
}
catch (StackOverflowError e)
{
driver.switchTo().alert().dismiss(); // or driver.switchTo().alert().accept();
// the rest of the scripts can be added here
}
