You can't access a database with JavaScript - you'll need to user some sort of Server Side program (in perl, Java, php etc.) to get the data from the database, then present it as a web page with your JavaScript in it.

Ok what I am looking to do is have an include file on a page. This include file will have info from the database, and I would like to be able to show this info in a scrolling text format.

PHP Code:
<script language=JavaScript>

//Typing Text (DHTML) v1 (Sunday, April 15th, 2001)
//Programmed by: Haitham M. Al-Beik
//Email: [email]albeik99@netzero.net[/email]
//Visit [url]http://javascriptkit.com[/url] for this script

var newsText = new Array();
newsText[0] = "Typing Text JScript v1\nDeveloped on Sunday, April 15th, 2001...";
newsText[1] = "This is a text-typing DHTML demo. \nScript featured on [url]http://javascriptkit.com[/url]";
newsText[2] = "Make sure you read the comments before you configure the script...";
newsText[3] = "Programmed by: Haitham Al-Beik...\n\nCopyright (c) Haitham M. Al-Beik, 2001";
newsText[4] = "http://www.prosheet.com/DHTML/typetext.htm"

var ttloop 1;    // Repeat forever? (1 = True; 0 = False)
var tspeed 50;   // Typing speed in milliseconds (larger number = slower)
var tdelay 1000// Time delay between newsTexts in milliseconds

// ------------- NO EDITING AFTER THIS LINE ------------- \\
var dwATextcnews=0eline=0cchar=0mxText;

function 
doNews() {
  
mxText newsText.length 1;
  
dwAText newsText[cnews];
  
setTimeout("addChar()",1000)
}
function 
addNews() {
  
cnews += 1;
  if (
cnews <= mxText) {
    
dwAText newsText[cnews];
    if (
dwAText.length != 0) {
      
document.news.news2.value "";
      
eline 0;
      
setTimeout("addChar()",tspeed)
    }
  }
}
function 
addChar() {
  if (
eline!=1) {
    if (
cchar != dwAText.length) {
      
nmttxt ""; for (var k=0k<=cchar;k++) nmttxt += dwAText.charAt(k);
      
document.news.news2.value nmttxt;
      
cchar += 1;
      if (
cchar != dwAText.lengthdocument.news.news2.value += "_";
    } else {
      
cchar 0;
      
eline 1;
    }
    if (
mxText==cnews && eline!=&& ttloop!=0) {
      
cnews 0setTimeout("addNews()",tdelay);
    } else 
setTimeout("addChar()",tspeed);
  } else {
    
setTimeout("addNews()",tdelay)
  }
}

doNews()
</script> 

I have the above script thet I got from another source, and I want to be able to alter it so that it would show the message from the database. The message would be in the form of a variable $message, how can I do this.

Tim
