Designing User Interfaces
Creating windows
JavaScript can open windows, which can display additional Web pages
inside. (Many browsers may include a feature to block pop-up windows. This
feature blocks JavaScript from opening a window because many pop-up ads
rely on JavaScript to display annoying ads on your screen.)
To create a window, you need to use the following:
variablename = window.open (“address”);
So if you wanted to open the Dummies Web site, you could use this code:
mywindow = window.open (“http://www.dummies.com”);
