Java Script Help (Banner Ad Rotator)

[L4A]

I was wondering if it would be possible to change the code of this script to miliseconds so more then 60 banners can be rotated (see script bellow).

Thats it.. pretty simple.. although I'm not sure exactly what your goal is.. There are better ways to do a simple banner rotation.

Cheers!

Thanx so much for the info and the quick reply! I'll give it a try this evening.

As for my goal....

I've been using the aforementioned script for several years now. I've been using it to rotate banner ads on one of my message boards. The way the script is written (using seconds), I can rotate a total of up to 60 banners. If I try to ad 61, the 61st banner does not appear in the rotation. I figured by using miliseconds instead of seconds, I would be able to rotate 61, 70, 80, etc, etc, etc, banners.

I'll give it a try tonight. Thank you!!

The above code change (see red) would be my preferred method for executing a random selection.

It's effectively the same with a few less lines of code.

Both will work however.

Cheers!

I like the "few less lines of code" thing!

psst...keep this between you and I. I'm a fisherman, not a programmer. So if I ask silly questions...

Silly Question #1 - If I use your example with the "fewer lines of code", will I be able to rotate an unlimited number of banners?

Thanx again for your prompt assistance! I really appreciate it!

[notjustgraphics]

Yes.. just change the first line to represent the total number of banners:

ie:

var how_many_ads = 99;

Cheers!

Thank you NJG! I used the option your prefered -

<!-- Begin
var how_many_ads = 61;
var ad = Math.ceil(how_many_ads*Math.random());

and it worked perfectly

Thank you!!

p.s let me know if ya ever need help catching a fish
