Hi,

This question is related to AJAX. I am trying to display a list of products for the category "Beverage" using the Northwind database.

When I click on the link "Beverage", I get thie error - "Unknown runtime error". In the code below, I made the error line bold.

What is causing it?

My code is:

Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "[URL unfurl="true"]http://www.w3.org/TR/html4/loose.dtd">[/URL]


<html>

<head>
<style type="text/css">
* {
   border: 0;
   padding: 0;
   margin: 0;
}

#menu {
  padding:0;
  margin:0;
  }
#menu li {
  list-style-type:none;
  }

#menu ul {
padding: 0;
margin: 6px;
list-style-type: none;
}

a.a_style:link {color:#0000ff; text-decoration:none;}
a.a_style:visited {color:#0000ff; text-decoration:none;}
a.a_style:hover {color:#ff0000; text-decoration:underline;}
a.a_style:hover {color:#ff0000; text-decoration:underline;}

</style>

<script type="text/javascript">


var xmlHttp

function showProducts(str)
{
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request")
return
}

var url="Categories_Dynamic1.asp"
url=url+"?ID="+str
alert(url);
//url=url+"&sid="+Math.random()
xmlHttp.onreadystatechange=stateChanged1
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
}

function stateChanged1()
{
	if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
	{
		//alert("State Changed");
		//objID = 'UI_'+el;
		//document.getElementById(objID).innerHTML=xmlHttp.responseText
		[b]document.getElementById("content_products").innerHTML=xmlHttp.responseText[/b]
	}
}

function GetXmlHttpObject()
{
var objXMLHttp=null
if (window.XMLHttpRequest) //Safari, Mozilla browers
{
	objXMLHttp=new XMLHttpRequest()
}
else if (window.ActiveXObject) //IE browsers
{
	objXMLHttp=new ActiveXObject("Microsoft.XMLHTTP")
}
return objXMLHttp
}

function s_Hide(el){
	alert("Showing Element: "+el);
	objID = 'UI_'+el;
	alert(objID);
	obj = document.getElementById(objID).style;
	(obj.display == 'none')? obj.display = 'block' : obj.display = 'none';
}

I added the above alert. I shows me a big grey color window which has all the code of my HTML page.

What should I be looking for?

Thanks.
