Uses simple functions defined in HEAD and called in BODY to to do such trivial tasks as changing background colors. Also includes a simple text box and button that does nothing more than echo text in an alert box.
Nothing really new here except that a random number generator is shown that randomly chooses from among 16 colors. Used to randomly change background colors using OnMouseOver event handler (not currently working in Netscape navigator). VERY HOKEY PAGE!! Apologies from Oldmanjoe.
Demonstrates the ability to put a scrolling message in the status bar.
Shows how a frame set (split screen) is defined.
Slightly more sophisticated manner of password checking, but still not a secure method of protecting information.
Special request from Johnny: Upper frame presents a text box into which you put a URL. The page referenced by the URL is presented in the bottom frame.
Slightly more sophisticated function for encoding/decoding. At least the encoding/decoding is symmetric. That is, encoded string is decoded into a string that when encoded gives you back the original string.
or not preceded
by a "#") to see what it looks like. Make up brand new colors of your own!(Just input 6-character strings consisting of any of the digits 0-9 or the alphabetical characters A-F.
This example provides a method for creating a pop-up window (that is admittedly Microsoft in nature) that opens and closes upon clicking the appropriate button.
Time for some fun! This example was given to me as part of a final project by one of my CSM 470 students. To follow the code, you have to be able to follow relatively simple C source code. I have no idea from where this script was stolen, but guaranteed, the student didn't write this code!
Are you interested in knowing how much time before the millennium bug kicks off and makes COBOL programmers all over the world (including me) rich?
More simple scrolling, but a chance for you to begin to understand the properties used with the methods associated with some of the built-in string objects. Do you know how to speed the scrolling up? Make the message longer or shorter? Etc.?
Here's some interesting code I picked up from a student (who probably stole it) that shows a number of things. It demonstrates how timers can be relatively easily built, but also shows exactly how the TR and TD tags work when making tables. Some knowledge of the C Programming Language helps here.
Don't click on this little example unless you are ready for some anxiety!!! Be careful where you place your mouse pointer -- from the first moment on!!! And oh yes: two points to whoever can get safely back to the Oldmanjoe Home Page without turning off your computer and
points (plus one ten year-old cat with no teeth) for anyone who can get safely back to this Table of Contents. -- So far, I only know how to get back to my home page, and even that takes a swift mouse movement while the lights are out. (You'll see what I mean soon enough!) If anyone knows a "quick fix" for this to work more smoothly, let me know in my Guest Book, okay?
