I need a scrolling text that will load the text  from a text file (.txt), so that the users will be able to change the text regularly. Maybe with an option of having some of the text link to another page. Thanks

A small demonstration with Ajax. Designed to run locally. Please do a further study to adapt to your environment. Here is the code:

<html>

	<head>

		<title>Script Demo Gops</title>

		<script language="javascript">

			function ajaxpage(url, containerid){

				var page_request = false

				if (window.XMLHttpRequest) // if Mozilla, Safari etc

					  page_request = new XMLHttpRequest()

				else if (window.ActiveXObject){ // if IE

					  try {

							page_request = new ActiveXObject("Msxml2.XMLHTTP")

					  }catch (e){

							try{

								  page_request = new ActiveXObject("Microsoft.XMLHTTP")

							}catch (e){}

					  }

				} else return false
 
 

				page_request.onreadystatechange=function(){

					  loadpage(page_request, containerid)

				}
 

				page_request.open('GET', url, true)

				page_request.send(null)

			}
 

			function loadpage(page_request, containerid){

				if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))

				document.getElementById(containerid).innerHTML=page_request.responseText

			}
 

			window.onload=function(){

				ajaxpage('marque.txt', 'mar');

			}

		</script>

	</head>

	<body topmargin="0" leftmargin="0" marginwidth="0" marginheight="0">

		<marquee style="position:absolute;left:100px;margin-top:100px;background-color:grey;width:200px;height:15px;font-family:verdana;font-size:11px;" scrolldelay="1000" id="mar">aaaa</marquee>

	</body>

</html>

Open in new window

You can type anything. Here is what I have:
marque.txt:
"This would be so slow, you'd get no sense of animation."

Sorry I think I'm missing something. the content of my marque.txt file is not displayed, but the text typed between the <marque > tags.

where have you placed the file? Is it in the same directory?
