AJAX Error: POST http://localhost/upload/undefined 404 (Not Found)

I have been searching the net and testing for hours now but I could not pinpoint what the error is. So, I am looking for your kind help here. I followed step by step multiple files upload tutorial with the drag & drop functionality but I got the error message as mentioned in the title (and the line of code that throws the error is xmlhttp.send(data); ).
File upload.js has this function:
(function(o) {
"use strict";
var ajax, getFormData, setProgress;
ajax = function(data) {
var xmlhttp = new XMLHttpRequest();
var uploaded;
xmlhttp.addEventListener('readystatechange', function() {
if (this.readyState === 4) {
if(this.status === 200){
uploaded = JSON.parse(this.response);
if(typeof o.options.finished === 'function'){
o.options.finished(uploaded);
}
} else {
if(typeof o.options.error === 'function'){
o.options.error();
}
}
}
});
xmlhttp.open('post', o.options.processor);
xmlhttp.send(data);
};
getFormData = function(source) {
var data = new FormData();
var i;
for(i = 0; i < source.length; i = i + 1) {
data.append('files[]', source[i]);
}
return data;
};
o.uploader = function(options) {
o.options = options;
if(o.options.files !== undefined) {
ajax(getFormData(o.options.files));
}
};
}());
and the global.js file has this code:
(function() {
"use strict";
var dropZone = document.getElementById('drop-zone');
var uploadsFinished = document.getElementById('uploads-finished');
var startUpload = function(files) {
app.uploader({
files: files,
Processor: 'upload.php',
finished: function(data){
var x;
var uploadedElement;
var uploadedAnchor;
var uploadStatus;
for (x = 0; x < data.length; x = x + 1) {
currFile = data[x];
uploadedElement = document.createElement('div');
uploadedElement.className = 'uploaded-console-upload';
uploadedAnchor = document.getElementById('a');
uploadedAnchor.textContent = currFile.name;
if(currFile.uploaded) {
uploadedAnchor.href = 'uploads/' + currFile.file;
}
uploadedStatus = document.createElement('span');
uploadedStatus.textContent = currFile.uploaded ? 'uploaded' : 'Failed';
uploadedElement.appendChild(uploadedAnchor);
uploadedElement.appendChild(uploadedStatus);
uploadsFinished.appendChild(uploadedElement);
}
uploadsFinished.className = '';
},
error: function() {
//console.log('There was an error');
}
});
};
//Standard form upload
document.getElementById('standard-upload').addEventListener('click', function(e) {
var standardUploadFiles = document.getElementById('standard-upload-files').files;
e.preventDefault();
startUpload();
});
//Drop funtionality
dropZone.ondrop = function(e){
e.preventDefault();
this.className = 'upload-console-drop';
startUpload(e.dataTransfer.files);
};
dropZone.ondragover = function() {
this.className = 'upload-console-drop drop';
return false;
};
dropZone.ondragleave = function() {
this.className = 'upload-console-drop';
return false;
};
}());
Any help to solve this problem would be greatly appreciated. Thank you.

o.options.processor was defined as Processor and when it was called back later in the code, it was referred to as processor (changing from Processor to processor) solved the case. Thank you guys with your comments that helped me to find the error.

Maintaining state of variables when changed inside a timer

I am using JavaScript.
I amusing a setInterval timer method.
Inside that method I am changing the values of module variables.
The thing is in IE the changes to the variables are not 'saved'. But in Chrome they are.
What is the accepted practice to do what I need to do?
this is my code:
function start()
{
var myVar = setInterval(function () { GetTimings() }, 100);
}
var currentts1;
var currentts2;
var currentts3;
var currentts4;
var frameCounter;
function GetTimings() {
if (frameCounter < 1) {
frameCounter++;
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", urlTS, false);
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState == 4) {
var nextts = xmlhttp.responseText;
var bits = nextts.split('|');
if (currentts1 != bits[0]) {
currentts1 = bits[0];
postMessage("0|" + bits[0]);
}
if (currentts2 != bits[1]) {
currentts2 = bits[1];
postMessage("1|" + bits[1]);
}
if (currentts3 != bits[2]) {
currentts3 = bits[2];
postMessage("2|" + bits[2]);
}
if (currentts4 != bits[3]) {
currentts4 = bits[3];
postMessage("3|" + bits[3]);
}
frameCounter--;
}
}
xmlhttp.send();
}
}
The variables:
currentts1
currentts2
currentts3
currentts4
frameCounter
values are not preserved...

Try this, but notice I changed the currentts* to an Array when you try to view them
function start() {
var myVar = setInterval(GetTimings, 100);
}
var currentts = [null, null, null, null];
var in_progress = 0; // clear name
function GetTimings() {
var xhr;
if (in_progress > 0) return; // die
++in_progress;
xhr = new XMLHttpRequest();
xhr.open('GET', urlTS);
function ready() {
var nextts = this.responseText,
bits = nextts.split('|'),
i;
for (i = 0; i < currentts.length; ++i)
if (currentts[i] !== bits[i])
currentts[i] = bits[i], postMessage(i + '|' + bits[i]);
--in_progress;
}
if ('onload' in xhr) // modern browser
xhr.addEventListener('load', ready);
else // ancient browser
xhr.onreadystatechange = function () {
if (this.readyState === 4 && xhr.status === 200)
ready.call(this);
};
// listen for error, too?
// begin request
xhr.send();
}

Javascript / ajax code - works in chrome and firefox but not in IE10

What I'm trying to do is limit the options of one select box based on what the user chooses in a prior select box. It works perfectly in Chrome and Firefox, but in IE 10 the only thing that shows up is the text "Not Found". I'm not sure, but my guess is that something is going wrong in request.status. What it is, however, I have no idea.
function prepForms() {
for (var i = 0; i<document.forms.length; i++) {
var thisform = document.forms[i];
var departCity = document.getElementById("departcity");
departCity.onchange = function() {
var new_content = document.getElementById("ajaxArrive");
if (submitFormWithAjax(thisform, new_content)) return false;
return true;
}
}
}
function getHTTPObject() {
if (typeof XMLHttpRequest == "undefined")
XMLHttpRequest = function() {
try { return new ActiveXObject("Msxml2.XMLHTTP.6.0"); }
catch (e) {}
try { return new ActiveXObject("Msxml2.XMLHTTP.3.0"); }
catch (e) {}
try { return new ActiveXObject("Msxml2.XMLHTTP"); }
catch (e) {}
return false;
}
return new XMLHttpRequest();
}
function submitFormWithAjax(whichform, thetarget) {
var request = getHTTPObject();
if (!request) {return false;}
var dataParts = [];
var element;
for (var i = 0; i<whichform.elements.length; i++) {
element = whichform.elements[i];
dataParts[i] = element.name + "=" + encodeURIComponent(element.value);
}
var data = dataParts.join("&");
request.open("POST", "flightlocationfilter.asp#ajaxArrive", true);
request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
request.onreadystatechange = function() {
if (request.readyState == 4) {
if (request.status == 200 || request.status == 0) {
var matches = request.responseText.match(/<div id="ajaxArrive">([\s\S]+)<\/div>/);
if (matches.length > 0) {
thetarget.innerHTML = matches[1];
} else {
thetarget.innerHTML = "<p>--Error--</p>";
}
} else {
thetarget.innerHTML = "<p>" + request.statusText + "</p>";
}
}
};
request.send(data);
return true;
};
Edit: After walking through with the IE Developer Tools, it looks like the request.readyState is not moving beyond 1 to 4.

Javascript in asp .Net

I'm getting WebResource error in my asp.Net page:
var __pendingCallbacks = new Array();
Microsoft JScript runtime error: 'Array' is undefined
I have no idea what might cause this to happen. Isn't Array part of Javascript itself? Any help would be appreciated.
EDIT
The problem is that this isn't code that I wrote, it's built into the page structure in asp.Net.
EDIT
The problem only occurs in IE9 and only when run in IE9 mode (not compatibility)
Code:
(This is dynamically generated code, sorry for the length. Problem is about halfway down)

This happens because we have this setup
<collapsible panel>
<iframe>
<script>
</script>
</iframe>
</collapsible panel>
When the page loads, the panel being shown forces the script inside the iframe to be dragged through the DOM before the javascript libraries are loaded. This seems to be a change in that was made for IE9. I have yet to fine a way around this issue but at least I know the cause. A temporary workaround is to force the compatibility of the page to IE8 using a meta tag in case anybody else runs into this issue.

The problem was fixed when I removed the SRC attribute from the iframe and I added onOpen event to jQuery's dialog:
open: function(){
document.getElementById("iframename").src = "page.aspx";
}

This IE error is probably related to the content-type header of the response sent from the server, where the charset may be invalid, or not what IE is expecting. A typical cause would be setting the charset to UTF8 instead of UTF-8.
Related article:
System error: -1072896658 in IE

The error message means that the encoding of the response is not supported.
Check the encoding of the page that you are getting. Most browsers are a bit relaxed about the syntax and accepts an encoding like UTF8, while IE demands the correct form UTF-8.

if you have charset=UTF8 change it to charset=utf-8 it will help... to solve your issue.
