Continuous Ajax.Request generates exception
Hi Group,
In my javascript, I am using consecutive Ajax.Request.
First Ajax.Request works perfectly but in case of second Ajax.Request
method call, it generates exception and it goes to onException: block.
I am not sure why such exception occurs. Any input on how to get rid
of such exception...
- R

What is the exception being fired? onException is an assignable
callback that accepts two arguments, the first being the actual
Ajax.Request object and the second being the exception that was
thrown. Alert that exception and let us know what it is and maybe
we''ll be able to better solve your problem.
Example:
new Ajax.Request(''index.html'',{
method: ''get'',
onException: function(req,exception) { alert(exception); }
});

I am getting following exception
"Reference Error: Processor not defined"
I have attached following scripts that generates exception.
var URL;
try
{
alert(new XMLSerializer().serializeToString(uriDoc));
var objNodeList = uriDoc.selectNodes(sXpath);
URL = ''http://localhost:8080/AT/ParserServlet?action=feed'';
for(i=0;i<objNodeList.length;i++)
{
var uriNode = objNodeList[i];
URL = URL +
''&uri''+i+''=''+uriNode.firstChild.nodeValue;
}
}catch(exception)
{
alert("Error occurred while loading stylesheet, :"+exception);
}
alert(URL);
//Sends request
new Ajax.Request(URL, {
method: ''get'',
onComplete: showConsole,
onException: function(req,exception){
alert("Exception while showin feeds :"+exception);//Here it generates
exception.
},
onError: function(req,exception){
alert("Error while showin feeds :"+exception);
}
});

Hi Ranjan, The XMLSerializer looks non-standard. Mozilla supports one out of the box, .NET for Ajax/Atlas has one (I think, not 100% sure about this one), and Sarissa provides a cross-browser one based on the Mozilla one. Which are you using (or is it something else that I haven''t come across)? A common issue when working with XML and prototype is that the Ajax classes in IE will return a version 2 MSXML ActiveX component (see line 757 of Prototype 1.5.0), even if version 3 or 4 are installed. If some other library is picking up or creating XML docs of a different version, they don''t often play well together, and cryptic errors get generated, although this doesn''t look like one I''ve seen before. You''re using XPath to selectNodes() - that''s only supported in MSXML 3.0 up, if I remember right. These are slightly wild guesses - tell us which browser you''re seeing the problems on, and I might be able to figure out a bit more.
