【问题描述】：

我创建了一个 Watir::Browser 的实例，并将 chrome 设置为浏览器。

b = Watir::Browser.new :chrome

如果我手动关闭警报，然后尝试使用

刷新页面

b.refresh

抛出以下错误：

Selenium::WebDriver::Error::UnhandledAlertError: unexpected alert open

当我调用b.alert.exists? 时，它会返回true。

我尝试使用b.alert.initialize 重置警报状态，但它引发了异常。

有没有办法完全重置浏览器对象的状态？

【问题讨论】：

same here alert not working...我也尝试使用 firefox，但没有多大成功。 b.alert.exists？ b.alert.ok 我在watirwebdriver.com/javascript-dialogs 上尝试了所有方法，但你运气不好？

【解决方案1】：

我也遇到过这个问题：

但我通过将其放入 begin-rescue 块中成功摆脱了它。

方法如下：

  begin
    # put line of code which triggers alert on page
  rescue Selenium::WebDriver::Error::UnhandledAlertError
    @browser.alert.ok 
  end
