1. In a new window, print all the properties of the
navigator
object.
2. Write a script that will display the name of your browser, the version, and the
operating system you are using. (Use the
parseInt()
function to print just the
version number.)
3. Does your browser support Shockwave Flash? Write a JavaScript program to
show whether the plug-in is installed.
4. Create two links, one to open a new window and one to close it. The new win-
dow will display this message in a big font:
The eye is the window to your soul.
The new window will be positioned in the left corner of your screen, will be
resizable, have a scrollbar, and it will have the focus.
5. Create an HTML document that contains four frames (i.e., four panes in a win-
dow, as in Figure 10.24). Each frame will display a different image. In another
window, use JavaScript to display the number of frames in the original window
and the name of the original window.
6. Create a program that produces a page containing frames. The first frame
will span across the top of the page and contain a centered heading entitled
A Virtual Zoo
. A second frame will be used as a navigation bar at the left side of
the screen. It will contain links to five animals. When the user clicks a link, an
image of that animal will appear in a frame of its own to the right side of the
navigation bar.
7. In an alert dialog box, display the pixel height, width, and color depth of your
screen. Each value will be separated by a newline.
8. Create a program that will create a digital clock in the status bar. Use the
setInterval()
method to update the status bar once every minute with the
current time.
