title: javascript: how to communicate between 2 windows?
body: <p>I understand how to open windows and communicate between the original window that opened the 2nd window and the 2nd window to communicate back to the original window. However, I have a situation where I have original page and page 1. These pages are 2 different PHP scripts that runs as a separate page. </p>
  
  <p>page 1 opens a window with clients webpage inside. We will call this window 1.</p>
  
  <p>Original page opens window 2 and window 3. These windows loads in php files that hold editing tools. I need these window 2 and window 3 to communicate with original page to edit window 1's content.  I don't see how this is possible.
  I only seen tutorials and books talking about original page and the windows it creates are the only ones that can access each other. So, I know in theory I cannot have the original page communicate with window 1 because window 1 was created by page 1. </p>
  
  <p>Is, there any way to work around this? The page 1 opens up content...like images, webpages...etc. I have it already setup this way. I need to be able to have my window tools to access the content window. That way they can edit webpages or images. How can I Do this if it's possible? </p>
  
  <p>No, that isn't the same question.  I need to modify the document to make changes to the html.  So, using cookies won't solve my problem. I need to edit t he content in the other window that was open by a different webpage but it's still part of the same domain. </p>
