JAVA SCRIPT
| The
third parameter of the window.open() method is a list of
features that you'd like your window to have. As you've seen, if
you don't include this parameter at all, the window will contain
all the features of a default browser window.
However, if you specify any features in the third parameter,
just those features will appear. The way to specify that you'd
like your window to have certain features is to list them as a
comma-separated list.
For example, if you write
|
window.open("some_url","window_name","location,menubar");
|
you'll get a window with just the location box (the place in
your browser where you type in a URL) and a menu bar (File, Edit,
etc.). Note that it's important that you don't put any spaces in
the string. This will upset some browsers.
Another example is
|
window.open("some_url","window_name","location,height=100,width=100");
| This
will open a window that is 100 pixels high and 100 pixels wide and
has no features other than a location field. Notice again that
there are no spaces in the string.
Here's a list of the features that you can include in the
feature string:
- menubar
- This is the row of functions that appears on most software
applications. Normally it includes File, Edit,
and a few other items.
- status
- This is the message bar at the bottom of your window. When
you move your mouse over an HTML link, the URL appears in the
status bar. You may have seen pages that use JavaScript to
turn this status bar into a scrolling marquee. I'm not
going to show you how to do this. If you want to know, you
have to figure it out yourself. "Down with
marquees," the monkey cried!
- scrollbars
- This allows scrollbars to appear when necessary.
- resizable
- If resizable is listed, the window can be resized.
Be careful of the spelling. I always get it wrong.
- width
- The width of the window in pixels.
- height
- The height of the window in pixels.
- toolbar
- The browser toolbar, which contains the Back and Forward
buttons, the Stop button, and the Home
button, among others.
- location
- The text area of a browser into which you can type URLs.
- directories
- The directories that Netscape browsers have called
"What's new," "What's cool," and so on.
Here are some examples of different type of windows.
Once you've checked out the examples, and maybe tried bringing
up some windows of your own, it's time to learn how to mess with
the contents of the windows.
