How to refresh a div on a click on a button

[Omar Ali]

Hello All,

I need your help in doing the ajax parto to refresh the div on the click on the "Refresh" button. I need an example.

I have tried to do it to be refreshed evey 15 seconds as per an example I found it in the internet.

Below is my code:

    <script type="text/javascript">
function Ajax(){
var xmlHttp;
	try{	
		xmlHttp=new XMLHttpRequest();// Firefox, Opera 8.0+, Safari
	}
	catch (e){
		try{
			xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); // Internet Explorer
		}
		catch (e){
		    try{
				xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
			}
			catch (e){
				alert("No AJAX!?");
				return false;
			}
		}
	}

xmlHttp.onreadystatechange=function(){
	if(xmlHttp.readyState==4){
		document.getElementById('ReloadThis').innerHTML=xmlHttp.responseText;
		setTimeout('Ajax()',10000);
	}
}
xmlHttp.open("GET","MQSTATUS.jsp",true);
xmlHttp.send(null);
}

window.onload=function(){
	setTimeout('Ajax()',10000);
}
</script>

it is giving me an error which is unknown runtime error in the line

xmlHttp.open("GET","MQSTATUS.jsp",true);

How should I modify the code, I tried to change the naming and do some modifications, but it did not work. I tried to put / before the url

xmlHttp.open("GET","/MQSTATUS.jsp",true);

But it did not work

Can anyone help

What is ReloadThis?
What is the responseText?

Reload is the name of the DIV

[Eric Pascarello]

And what is the responseText?

Have you used Fiddler to see if the Ajax call is being made?

No I did not use.

Is there is a way to check? or an example?

Install fiddler, it will capture the traffic.

Most built-in debuggers in modern browsers will show the network traffic. You really need to learn to use the tools at your disposal.
