A few of the scripts utilize Javascript 1.2, which was released with Netscape Communicator 4,

I am working on a mini arcade-style game with layers, but it isn't quite presentable yet.
DateFormat is a set of JavaScript functions that allow you to "feed" DateFormat
a format code and a date object (such as new Date() for the current date or
document.lastModified for the current pages last modified date). DateFormat
then parses the format code with the date object and returns a string representing the date in
the format that was specified. DateFormat is complex enough that it has its own page,
right here.
The code:
function randomBetween(low,high,rounded){
if(rounded)
return Math.round((high - low) * Math.random() + 1);
return ((high - low) * Math.random() + 1);
};
Use:
randomBetween(low,high,rounded)
Where the random number is between low and high, and rounded is true
or false, meaing whether or not the random number is a whole number (rounded).
Example:
<A HREF="javascript:alert(randomBetween(1,1000,true))">Display a random whole number
between 1 and 1000</A>
Display a random whole number between 1 and 1000
The code:
function numberEnding(num){
if(num >= 4 && num <= 20)
{
return "th";
}
lastDigit = num.toString().charAt(num.toString().length-1);
switch(lastDigit)
{
case "1":
return "st";
case "2":
return "nd";
case "3":
return "rd";
case "0":
return "th";
}
return "th";
}
Use:
numberEnding(number)
Where number is the number to find an ending for.
Example:
<SCRIPT>
function alertEnding(number){
alert(number + numberEnding(number));
}
</SCRIPT>
<A HREF="javascript:alertEnding(prompt('Enter any whole number.',''))">Click for example</A>

I have a model rocket page too!
