Question

Is there any way other than XMLHttpRequest.responseText.length to get the current download progress of an AJAX request?

I ask this because IE just gives up with a “data not yet available” error. Other browsers have no issues, but I’d like to be able to at least give some indication of progress.

The progress event’s support is limited to version 10 in terms of Internet Explorer, but you didn’t specify a version…

rq.onprogress = function(e) {
    if(e.lengthComputable) {
        progressElement.textContent = Math.floor(e.loaded / e.total * 100) + "%";
    }
};
