Thread: ajax return undefined

hi
i m using ajax like this

Code:

var sTarget = 'EmergencyDocCreation_CheckForInvoiceDuplicate.asp';
						sTarget += '?SupplierID=<%=lSupplierID%>';
						sTarget += '&DocumentRef=' + escape($('txtDocumentRef').value);
						sTarget += '&DocumentDate=' + escape($('txtDocumentDate').value);
						sTarget += '&ValueExclVAT=' + escape($('txtDocumentExclVAT').value);						

						//Check for duplicate invoice
						 var ajaxRequest  = new Ajax.Request(sTarget,
										 { 
											evalScripts: true, 
											asynchronous: false
	 									 }
   										);
				alert(ajaxRequest.responseText); 

Code:

	'Get parameters from the querystring
	lSupplierID = CLng(Request.QueryString("SupplierID"))
	sDocumentRef = Request.QueryString("DocumentRef")
	sDocumentDate = Request.QueryString("DocumentDate")
	sValueExclVAT = Request.QueryString("ValueExclVAT")
  
  'Response.ContentType = "text/javascript"
  Response.write "<script type=""text/javascript"">alert('hello');</script>"
  Response.End

i m getting undefined value it should return hello alert.
what i m missing??
thanks

What exactly are you trying to do with this? Why use AJAX to display a JavaScript alert?

actaully i m checking my ajax code is working or not .

Okay, give me some details. What is this AJAX supposed to do?

see i m calling asp file with query string .i m calling this way

Code:

var sTarget = 'EmergencyDocCreation_CheckForInvoiceDuplicate.asp';
						sTarget += '?SupplierID=<%=lSupplierID%>';
						sTarget += '&DocumentRef=' + escape($('txtDocumentRef').value);
						sTarget += '&DocumentDate=' + escape($('txtDocumentDate').value);
						sTarget += '&ValueExclVAT=' + escape($('txtDocumentExclVAT').value);						

						//Check for duplicate invoice
						 var ajaxRequest  = new Ajax.Request(sTarget,
										 { 
											evalScripts: true, 
											asynchronous: false
	 									 }
   										);

now before everything i want to check that my querystring value is reaching at asp page or not .if i m getting querystring at my asp page then i assume my ajax code is working.
hope it make some sense.

Take a look at the AJAX tutorial here: Ajax Tutorial - XMLHttpRequest

Unless I'm missing something or not understanding something, I don't see where you are Opening the request to the specified page.

here i m opening request.i dont want to use xmlhttp request.
var ajaxRequest = new Ajax.Request(sTarget,
{
evalScripts: true,
asynchronous: false
}

Okay, just to warn you, my custom AJAX is far from great...but what happens with something like this:

Code:

var url = ''EmergencyDocCreation_CheckForInvoiceDuplicate.asp' 
url += '?SupplierID=<%=lSupplierID%>';
url += '&DocumentRef=' + escape($('txtDocumentRef').value);
url += '&DocumentDate=' + escape($('txtDocumentDate').value);
url += '&ValueExclVAT=' + escape($('txtDocumentExclVAT').value); 
url = encodeURIComponent(url);  
new Ajax.Request(url, { 
  method: 'get', 
  evalJS: true,
  asynchronous: false,
  onSuccess: function(transport) { 
    // Alert on success
    alert('Hello World');
  } 
});

I'm unable to test on my end...does it state what line the error occurs on?
