Not enough arguments?

[cyphix]

Hey guys..... I've been going over this code for the last few hours & it seems once I get past one problem there is another.... this is frustrating... at the moment I'm getting a javascript error of "not enough arguments"..

Here is the error:



Here is the javascript code:

function getModels()
{

 var xmlHttp

 xmlHttp=GetXmlHttpObject();
	
	if (xmlHttp==null)
	  {
	  alert ("Your browser does not support AJAX!");
	  return;
	  }
	  
 var url="xml.xml";
 xmlHttp.open("GET",url,true);
 xmlHttp.setRequestHeader("Content-Type: text/xml; charset=utf-8");
 xmlHttp.send(null);
 
 	 xmlHttp.onreadystatechange=function() {
 
	 	if (xmlHttp.readyState==4) {
 
 		poo = xmlHttp.responseXML.documentElement;
 		alert(poo.getElementsByTagName("book")[0].nodeValue);
 		return;
 
	 	 var books = xmlHttp.responseXML.getElementsByTagName('book');
	
			for (var i=0;i<books.length;i++)
			{
				var x = document.createElement('div');
				x.className = 'book';
				var y = document.createElement('h3');
				y.appendChild(document.createTextNode(getNodeValue(books[i],'title')));
				x.appendChild(y);
				var z = document.createElement('p');
				z.className = 'moreInfo';
				z.appendChild(document.createTextNode('By ' + getNodeValue(books[i],'author') + ', ' + getNodeValue(books[i],'publisher')));
				x.appendChild(z);
				var a = document.createElement('img');
				a.src = books[i].getElementsByTagName('cover')[0].getAttribute('src');
				x.appendChild(a);
				var b = document.createElement('p');
				b.appendChild(document.createTextNode(getNodeValue(books[i],'blurb')));
				x.appendChild(b);
				document.getElementById('blah').appendChild(x);
			}
		
		}
		
	}
	
}

function getNodeValue(obj,tag)
{
	return obj.getElementsByTagName(tag)[0].firstChild.nodeValue;
}

function GetXmlHttpObject()
{
var xmlHttp=null;
try
  {
  // Firefox, Opera 8.0+, Safari
  xmlHttp=new XMLHttpRequest();
  }
catch (e)
  {
  // Internet Explorer
  try
    {
    xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
    }
  catch (e)
    {
    xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
  }
return xmlHttp;
}

Here is my XML file..

try moving send after you set the onreadystatechange

nope.. same problem.

[bipins]

your problem is in the send() function

pass something there.
besides null.

I had the same problem
and it worked when i passed something to the send function.
