Topic awaiting preservation: looking for a script... (Page 1 of 1)

That changes an image/chooses a random image on refresh.

I know that I have seen it around somewhere, but can't think of where... can anyone help me?

Thanks alot in advance!

I've used this one earlier. No doubt someone will post a smarter better one, but what the..

<Script Language ="JavaScript">



function RandomNumber() 

{

  var today = new Date();

  var num= Math.abs(Math.sin(today.getTime()/1000));

  return num;

}



function RandomGraphics() 

{

  var x = RandomNumber();



  if (x > .77) {document.write("<img src='image here' align=center border=0>"); return; }

  if (x > .66) {document.write("<img src='image here' align=center border=0>"); return; }

  if (x > .55) {document.write("<img src='image here' align=center border=0>"); return; }

  if (x > .44) {document.write("<img src='image here' align=center border=0>"); return; }

  if (x > .33) {document.write("<img src='image here' align=center border=0>"); return; }

  if (x > .22) {document.write("<img src='image here' align=center border=0>"); return; }

  if (x > .11) {document.write("<img src='image here' align=center border=0>"); return; }

  if (x > 0)   {document.write("<img src='image here' align=center border=0>"); return; }

}





//End Script 



</SCRIPT>

the date-trick is cool, nimraw.

but JS also features Math.random() which returns a pseudo-random number between 0.0 and 1.0.
(we all know that something like random doesnt really exists on a computer )

We have done so.

Don't follow his example - seek real life help first.

Gruble: Yeah, I know, but when I tested that some numbers were favored.

I usually use a function that checks clock seconds and and control the pseudo-random from that aspect. The user should statisticly load the page with even distributíon over the second span. (or so i figger)

Thanks you guys, I really appreciate your responses! I am a little busy with something else at the moment, but will try out your solutions a little later this evening.

To answer the question:

does it mean you want a generic image to be always there on FIRST LOAD,
and then a random image on any subsequent REFRESH of that page? What I would like to do is have a set folder of images that are the same size, and the placement on the page is the same, but everytime the page is accessed/refreshed, a new/different/random image is shown. Does that make sense? As in I have image a, b, c, etc, but A does not have to be there the first time it loads, but everytime it is refreshed a new, random image is displayed.


Ini, it is not that I don't give a f*** about coding, I really respect those who can, but I am just not one of them! I have tried, really I have, but I just don't even get it! (It must be the blonde hair!) But I can copy and paste, and mess around a little, trial and error modifications and such.... but no, I am not a math person!

So once again, thank you Nimraw, Grumble, and Ini!

How cool is this?

Just today I wanted to find a random image script, so I wander down the hall to the DHTML/Javascript Cell and paydirt! There is already a topic with the answer to my question. I love this place.


These eyes have walls.

I'm having trouble with your script InI.

The only image it will produce is image10.gif. I tested it out by changing n=10 to n=5 and it would then only produce image5.gif. Am I doing something wrong?

.... And it's double-cool, 'cause I was comming in to say thanks it worked! Here is the fix Blook:

Change:

document.write("<img src='image"+n+".gif' border=0>");

to:

document.write("<img src='image"+r+".gif' border=0>");

change the +n+ to +r+ (I think Ini was testing me!!)

So does n=x where x=the number of images you have?

Seems like my hunch was right. No need to answer. Thanks for the help everyone.
