[Watir]Control the popup windows created using javascript

These are pop ups created using javascript. The ones below come from the watir unit tests.

They would be created using javascript, and an example is shown under each of them.

<input type = button onClick = 'javascript:x = confirm('Do you really want to do this');">

<input type = button onClick = 'javascript:y = prompt('Enter Something Useful');">

<input type = button onClick = 'javascript:z = alert('This is an alert box');">

# Auto Popup Handler. Posted by brad@longbrothers.net
#
require 'win32ole'  # already included if you use 'require watir'
#
# Function to look for popups
def check_for_popups
autoit = WIN32OLE.new('AutoItX3.Control')
#
# Do forever - assumes popups could occur anywhere/anytime in your application.
loop do
# Look for window with given title. Give up after 1 second.
ret = autoit.WinWait('Popup Window Title', '', 1)
#
# If window found, send appropriate keystroke (e.g. {enter}, {Y}, {N}).
if (ret==1) then autoit.Send('{enter}') end

# Take a rest to avoid chewing up cycles and give another thread a go.

# A Better Popup Handler using the latest Watir version. Posted by Mark_cain@rl.gov

require 'watir/contrib/enabled_popup'

require 'Watir'
require 'watir/contrib/enabled_popup'

# Use click_no_wait to launch the popup or your script will hang
browser.button(:id, /someText/).click_no_wait

hwnd = browser.enabled_popup(5)
if (hwnd)  #yeah! a popup
popup = WinClicker.new
popup.makeWindowActive(hwnd)
popup.clickWindowsButton("Windows Internet Explorer", "OK", "30")

Solution #5 - Summary - 09 July 2008

I spent some time trying to figure out how to dismiss javascript popups. The information is out there, but it took a while to get it all put together and then to try out the various suggestions until I found one that worked for me. Here's a summary in case it helps someone else.

1.) You need to update the winClicker.rb file in your watir directory(in my case, it was at: c:/ruby/lib/ruby/gems/1.8/gems/watir-1.5.3/watir). Change the dialog title from "Internet Explorer" to "Windows Internet Explorer". I used the regex /Internet Explorer/ so that it will work no matter which version of IE I use.

2.) Require 'watir/contrib/enabled_popup' for your tests.

3.) Define the popupChecker method to watch for a popup and dismiss it (in this case, by clicking the button with the specified text):

def popupChecker(text)
Timeout::timeout(2)do
begin
if ie.enabled_popup
hwnd = ie.enabled_popup(5)
w = WinClicker.new
w.makeWindowActive(hwnd)
w.clickWindowsButton_hWnd(hwnd,text)
end
rescue Timeout::Error
puts 'No popup existed'
end
end
end

4.) Use the click_no_wait method on the link or button that will launch the popup.

ie.button(:text, 'Continue').click_no_wait

5.) Call the popupChecker method in case a popup exists. You may run into timing problems with the Watir actions that follow the popupChecker. To get around this, I added an ie.wait statement after calling the popupChecker method.

popupChecker('OK')
ie.wait

6.) Some popups are launched by selecting an item from a select_list. Since the click_no_wait method is required on the action that launches the popup, you need something like a select_no_wait method for a select list. Charley Baker provided me with this method:

#select_no_wait method for select lists - needed for popups resulting from select lists
module Watir
class Element
#select_no_wait - selects a drop-down element spawning a new process.
#this is needed to close potential pop-ups that select drop-down can trigger.
def select_no_wait(item)
assert_enabled
highlight(:set)
object = "#{self.class}.new(self, :unique_number,#{self.unique_number})"
@page_container.eval_in_spawned_process(object + ".select('#{item}')")
highlight(:clear)
end
end
end

7.) Many people has the problem about click "OK/Cancel" or "OK" in the pop up. I think the code below can deal with the problem

require 'watir'
def check_for_popups(title="Window Internet Explorer", button="OK")
popup=Thread.new {
autoit=WIN32OLE.new('AutoItX3.Control')
ret=autoit.WinWait(title,"",60)
if (ret==1)
puts "There is popup."
autoit.WinActivate(title)
button.downcase!
if button.eql?("ok") || button.eql?("yes") || button.eql?("continue")
autoit.Send("{Enter}")
else
autoit.Send("{tab}")
autoit.Send("{Enter}")
end
elsif (ret==0)
puts "No popup, please check your code."
end
}
at_exit { Thread.kill(popup) }
end

$ie.link(:text,//).click_no_wait
check_for_popups("Window Internet Explorer", "OK")
