popups.

If you want to open a new browser window from a link, and have it validate, you'll need to use the following code for your link such as www.unomaha.edu (do not copy and paste from this page):

<a href="#" title="Link will open a new window!" onkeypress="window.open('http://www.whatever.com')" onclick="window.open('http://www.whatever.com')">Whatever</a>

Now suppose you want to pop up a reusable window. For instance, if you wanted a glossary page to pop open a window with the definitions, and reuse that (popped) window for subsequent definitions. That code would look like this (do not copy and paste from this page):

<a href="#" title="Link will open a new window!" onkeypress="var w=window.open('http://www.unomaha.edu','popped'); w.focus(); return false;" onclick="var w=window.open('http://www.unomaha.edu','popped'); w.focus(); return false;">UNO</a>

In either case, you can control the various attributes of the popped window, such as the size, scrollbars, and etcetera — but that is all a bit beyond the scope of this documentation.
