Step 1: Simply add the below code where you wish the scroller to appear in the <body>:
<script language="JavaScript1.2">
/*
Fading Scroller- By DynamicDrive.com
For full source code, and usage terms, visit http://www.dynamicdrive.com
This notice MUST stay intact for use
*/
var delay=3000 //set delay between message change (in miliseconds)
var fcontent=new Array()
begintag='<font face="Arial" size=2>' //set opening tag, such as font declarations
fcontent[0]="<b>What\'s new?</b><br>New scripts added to the Scroller category!<br><br>The MoreZone has been updated. <a href='../morezone/index.htm'>Click here to visit</a>"
fcontent[1]="Dynamic Drive has been featured on Jars as a top 5% resource, and About.com as a recommended DHTML destination."
fcontent[2]="Ok, enough with these pointless messages. You get the idea behind this script.</a>"
closetag='</font>'
var fwidth='150px' //set scroller width
var fheight='150px' //set scroller height
var fadescheme=0 //set 0 to fade text color from (white to black), 1 for (black to white)
var fadelinks=1 //should links inside scroller content also fade like text? 0 for no, 1 for yes.
///No need to edit below this line/////////////////
var hex=(fadescheme==0)? 255 : 0
var startcolor=(fadescheme==0)? "rgb(255,255,255)" : "rgb(0,0,0)"
var endcolor=(fadescheme==0)? "rgb(0,0,0)" : "rgb(255,255,255)"
var ie4=document.all&&!document.getElementById
var ns4=document.layers
var DOM2=document.getElementById
var faderdelay=0
var index=0
if (DOM2)
faderdelay=2000
//function to change content
function changecontent(){
if (index>=fcontent.length)
index=0
if (DOM2){
document.getElementById("fscroller").style.color=startcolor
document.getElementById("fscroller").innerHTML=begintag+fcontent[index]+closetag
linksobj=document.getElementById("fscroller").getElementsByTagName("A")
if (fadelinks)
linkcolorchange(linksobj)
colorfade()
}
else if (ie4)
document.all.fscroller.innerHTML=begintag+fcontent[index]+closetag
else if (ns4){
document.fscrollerns.document.fscrollerns_sub.document.write(begintag+fcontent[index]+closetag)
document.fscrollerns.document.fscrollerns_sub.document.close()
}
index++
setTimeout("changecontent()",delay+faderdelay)
}
// colorfade() partially by Marcio Galli for Netscape Communications. ////////////
// Modified by Dynamicdrive.com
frame=20;
function linkcolorchange(obj){
if (obj.length>0){
for (i=0;i<obj.length;i++)
obj[i].style.color="rgb("+hex+","+hex+","+hex+")"
}
}
function colorfade() {
// 20 frames fading process
if(frame>0) {
hex=(fadescheme==0)? hex-12 : hex+12 // increase or decrease color value depd on fadescheme
document.getElementById("fscroller").style.color="rgb("+hex+","+hex+","+hex+")"; // Set color value.
if (fadelinks)
linkcolorchange(linksobj)
frame--;
setTimeout("colorfade()",20);
}
else{
document.getElementById("fscroller").style.color=endcolor;
frame=20;
hex=(fadescheme==0)? 255 : 0
}
}
if (ie4||DOM2)
document.write('<div id="fscroller" style="border:1px solid black;width:'+fwidth+';height:'+fheight+';padding:2px"></div>')
window.onload=changecontent
</script>
<ilayer id="fscrollerns" width=&{fwidth}; height=&{fheight};><layer id="fscrollerns_sub" width=&{fwidth}; height=&{fheight}; left=0 top=0></layer></ilayer>
Configuring the scroller
You can easily configure the width/height, font, and contents of the scroller. Just change the first few variables of the script to do so. |
