Creating Accessible Popups

As some might know, I am currently writing a chapter for “Constructing Accessible Web Sites” by Apress / Friends of Ed. As an example, I am writing a script to allow for “accessible” pop-up windows. I had an idea I hadn’t seen yet before and wondered if I should pursue with it. Here’s the deal:

• We cannot assume that the user agent allows for popup windows
• When we only use HTML and the target attribute, we can open a window, but cannot “style” it or close it with a button
• When we have JavaScript enabled and we have a window.opener, we can assume that the window was opened and we can add window.close() links.

Therefore I considered using link relationships in conjunction with a script to make the whole process failsafe: [popup](/2005/07/24/creating-accessible-popups/popup.html) would be changed by the script to a link opening the new window and get a message attached that it does so. [back](/2005/07/24/creating-accessible-popups/parent.html) would get a close.window() attached and the text changed to “close window”. Any comments why that is a bad idea and what would be a better one? Yes, I will point out that popups should be avoided.
