Question

我注意到一些奇怪的事情。如果我使用Firefox，这可以正常工作：

require "selenium-webdriver"
# => true 

driver = Selenium::WebDriver.for :firefox
# => #<Selenium::WebDriver::Driver:0x..fc3c6738535bdb898 browser=:firefox> 

driver.execute_script "window.alert('text');"
# => "text"

警报弹出窗口打开。

如果我对Chrome执行相同操作，则会打开警报弹出窗口，但我会收到例外情况：

driver = Selenium::WebDriver.for :chrome
# => #<Selenium::WebDriver::Driver:0x47f3180ec45394e8 browser=:chrome> 

driver.execute_script "window.alert('text');"
Selenium::WebDriver::Error::UnhandledAlertError: Script execution failed. Script: window.alert('text');;
 An open modal dialog blocked the operation

我在这里做错了吗？

环境：

Mac OS X 10.7.3
Firefox 10.0.2
Chrome 17.0.963.56
chromedriver_mac_18.0.1022.0
Ruby ruby 1.9.2p290
selenium-webdriver 2.19.0

使用chromedriver再次尝试使用。 Java的例子：

ChromeDriver driver = new ChromeDriver();

driver.executeAsyncScript("arguments[0](); alert('Hello')");
try {
    Thread.sleep(3000);
} catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Selenium :: WebDriver :: Error :: UnhandledAlertError：脚本执行失败。打开模式对话框阻止了操作
