DOMInclude: Replacing pop-ups:

DOMInclude is a library that allows you to add inline dynamic includes of content rather than using window popups.

Pop-up windows are a pain for both the developer and the users. Often enough a page needs to link to a terms and conditions document and as the client does not want the user to leave the page you are asked to implement them in a pop-up.

The problem with this are technical and psychological:

years of unsolicited pop-up windows have conditioned users to immediately close windows when they open
the same reason and security concerns made people install pop-up blocker software and browsers to include pop-up blocking options, and depending on their configuration these may even block your “friendly pop-ups”.

nice cool.
