9.4 Pop Up Windows

A window that suddenly appears (pops up) when you select an option with a mouse or press a
special function key. Usually, the pop-up window contains a menu of commands and stays on
the screen only until you select one of the commands. It then disappears.

A special kind of pop-up window is a pull-down menu, which appears just below the item you
selected, as if you had pulled it down.
A popup window is a web browser window that is smaller than standard windows and without
some of the standard features such as tool bars or status bars. For instance, this link opens a
medium-sized popup window.

Did u know? Popup windows (aka popups) are popular for small sidebar-style pages that
are digressions from the main page.
Popups are one of the trickiest effects in web development. More than one web developer has
been reduced to tears trying to get popups to work correctly. Furthermore, some irresponsible
popup techniques have made many web pages handicapped and search engine inaccessible.

This topic will walk you step-by-step through creating popup windows, including giving you a
complete set of copy-and-paste JavaScript code. We’ll start with a basic example, showing the
main pieces to a popup. Then we’ll show the techniques for targeting a link inside the popup
back to the main page. Finally we’ll work through the many parameters for the open() command
that adds features to your popups.

Example: Use the Dreamweaver behaviors panel to create small pop-up windows for
ads or news!
This behavior helps to create pop-up ads, small browser windows etc. If you don’t have
Dreamweaver we have provided the code that you can cut ‘n’ paste and use in your web page.
