How to use watir-webdriver to wait for page load

Today's release adds an optional require that brings in some helpers for waiting for elements. These are not (at the moment) available in Watir 1.6, so be aware if you use both libraries side by side.

Check "AJAX and waiting for elements" in the Watir-webdriver Wiki for more information.

The best summary is found in "Waiting".

This is it in a nutshell:

require 'watir-webdriver'
b = Watir::Browser.start 'bit.ly/watir-webdriver-demo'
b.select_list(:id => 'entry_1').wait_until_present
b.text_field(:id => 'entry_0').when_present.set 'your name'
b.button(:value => 'Submit').click
b.button(:value => 'Submit').wait_while_present
Watir::Wait.until { b.text.include? 'Thank you' }

I don't know if they're the best way, but this is how I'm handling this for waiting for an updating div to clear:

while browser.div(:id=>"updating_div").visible? do sleep 1 end

This is how I handle waiting for something to display:

until browser.div(:id=>"some_div").exists? do sleep 1 end
