I am trying to use object-oriented code to handle an AJAX upload. When I run the code, it sees the file, creates the XMLHttpRequest object, but I cannot seem to get the progress event to fire. The full source of my code can be found here: http://pastebin.com/89QawbS6
Here is a snippet:
var xhr = new XMLHttpRequest();
xhr.upload.addEventListener("progress", MyObj.trackProgress, false);
xhr.open("POST", url, true);
...
Then in that same object, different method:
trackProgress: function (event) {
console.log(event);
// stuff that should calculate percent
}
But that console.log(event) never fires.
Please note: I know jQuery is great, and there are a dozen awesome upload plugins that I could just use instead. I am not doing this for a class or homework, I just want to understand the process better myself. So offering a jQuery plugin as an answer is not what I'm looking for. I'm trying to make myself less dependent on jQuery.
