Planning pop-up windows.
A pop-up window is used to add additional information to a Web page. You must decide
what features you want the pop-up window to utilize. Ask yourself these questions:
Do you want to include the status bar, title bar, address bar, scroll bars, toolbars, and
•
menu bar?
Do you want the user to be able to resize the window?
•
•
Each of these properties can be set as properties in the open() method, creating a custom-
ized look for that particular pop-up window.
What width and height should the window be?
Adding a Pop-Up Window
Pop-up Windows
In addition to alert()
message boxes, Web
developers use pop-up
windows to display more
information or to gain
attention. Use pop-up
windows sparingly because
having many pop-up
windows can annoy visitors.
As you have learned in this chapter, the alert() method is one way to display messages to
a user. These message boxes, however, only display text on a gray background. To create
more visually interesting messages, you can use JavaScript to open and display another
HTML file in a separate window that displays colors, graphics, animations, and other
media. Such a window is called a
pop-up window
because it appears over the previously
opened browser window.
