js random thingy

[diacono]

i'm not fluent in js, i just tinker around, copying changing and sometimes make som scripts better!

but i've tried with this and just cant, how do i make this random??

<script language="JavaScript1.2">

/*
Fading Ticker Tape Script-
*/
//default speed is 4.5 seconds, Change that as desired
var speed=8000

var news=new Array()
news[0]="1st text"
news[1]="2nd text"
news[2]="3rd text"

i=0
if (document.all)
tickerobject=document.all.subtickertape.style
else
tickerobject=document.tickertape.document
function regenerate(){
window.location.reload()
}
function regenerate2(){
if (document.layers)
setTimeout("window.onresize=regenerate",450)
}

function update(){
BgFade(0xff,0xff,0xff, 0x00,0x00,0x00,30);
if (document.layers){
document.tickertape.document.subtickertape.document.write('<span class="subtickertapefont">'+news[i]+'</span>')
document.tickertape.document.subtickertape.document.close()
}
else
document.all.subtickertape.innerHTML=news[i]

if (i<news.length-1)
i++
else
i=0
setTimeout("update()",speed)
}

function BgFade(red1, grn1, blu1, red2,
grn2, blu2, steps) {
sred = red1; sgrn = grn1; sblu = blu1;
ered = red2; egrn = grn2; eblu = blu2;
inc = steps;
step = 0;
RunFader();
}
function RunFader() {
var epct = step/inc;
var spct = 1 - epct;
if (document.layers)
tickerobject.bgColor =
Math.floor(sred * spct + ered *
epct)*256*256 +
Math.floor(sgrn * spct + egrn * epct)*256 +
Math.floor(sblu * spct + eblu * epct);
else
tickerobject.backgroundColor=
Math.floor(sred * spct + ered *
epct)*256*256 +
Math.floor(sgrn * spct + egrn * epct)*256 +
Math.floor(sblu * spct + eblu * epct);
if ( step < inc ) {
setTimeout('RunFader()',1);
}
step++;
}

</script>

you can find a working one here at the bottom or better here

thanx

Hello diacono,

I've moved your post to Client Side Scripting (Javascript) to help give you a better answer on randomizing your ticker tape script.

I'm sure our javascript gurus will help you find the answer you're looking for.
