Not a function ... why????????????

[nloding]

Here's how I call this code ... it's my wrapper for Ajax:

 

var ajax = new XMLHttp();
ajax.get('myscript.php?variable=value');

 

When I run that, I get the error in Firefox's Error Console that ajax.get is not a function.  So I've checked this code ten times and I see nothing wrong.  It's almost copied exactly from an example I saw online, and that example works (so says the author, it's from About.com).  Here's all the pertinent javascript code:

 

function XMLHttp() {
if (window.XMLHttpRequest) { // If we have a Gecko browswer?
	return new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE is more difficult ...
	var avers = ["Microsoft.XmlHttp", "MSXML2.XmlHttp", "MSXML2.XmlHttp.3.0",  "MSXML2.XmlHttp.4.0", "MSXML2.XmlHttp.5.0"];
	for (var i = avers.length -1; i >= 0; i--) {
		try {
			httpObj = new ActiveXObject(avers[i]);
			return httpObj;
		} catch(e) {}
	}
}    

// And what if the the browser sucks?
alert("Your broswer is too old. Consider upgrading!");
}

XMLHttp.prototype.get = function(url, element) {
this.open('GET', url, true);
this.onreadystatechange = function() {
	this.processRequest(element);
}
this.send(null);
}

XMLHttp.prototype.processRequest = function(element) {
if (this.readyState == 4 && this.status == 200) {
	findElement(element).innerHTML = this.responseText;
}
}

function findElement(target) {
var targetElem = document.getElementById(target);

if(!targetElem) {
	targetElem = getElementsByClassName(document, "*", target);
}

return targetElem;
}

 

The XMLHttp() function works fine, as I can use ajax.open and ajax.onreadystatechange.  But I can't use ajax.get ... I've tried calling the XMLHttp() function without "new" before it ...

 

I'm lost ... what's wrong with that code?

No idea... maybe something magical about hte name.

Yeah, that's totally not fair!

 

I keep getting the 0x80040111 Firefox error because for some reason my abort() commands aren't killing my Ajax connection ... so I get weird errors and timeouts when calling the Ajax object more than once.  I'm wondering if that's the reason.  But if I close the browser, clear all private data, and try again, same deal -- same error "ajax.get is not a function".

 

I'm totally lost.  There's nothing wrong with that code.  I'll change my "ajax" var to "myObj", and "XMLHttp" to "reqObj" or something and see what happens, but that shouldn't make a difference.  Those aren't restricted names.
