Answer 1

As of the latest selenium 2 release, this can be done (at least using the FirefoxDriver):

    driver.switchTo().alert().accept();

Answer 2

In Selenium 2, currently alerts are only handled in the Firefox browser. You don't specify what language you're using for your tests, but here's how to handle an alert using ruby. (This is taken from the Ruby Bindings page on the selenium wiki).

Javascript Alert/Confirm

You can use webdriver to handle javascript alert and confirm dialogs. The implementation for both is the same.

Note: At this time the API is only available in Firefox (or in Firefox using the remote server), and only alert/confirms that are generated post load can be captured.

require "selenium-webdriver"

driver = Selenium::WebDriver.for :firefox
driver.navigate.to "http://mysite.com/page_with_alert.html"

driver.find_element(:name, 'element_with_alert_javascript').click
a = driver.switch_to.alert
if a.text == 'A value you are looking for'
  a.dismiss
else
  a.accept
end
