HTML5 FileReader alternative

Question

I need some help with HTML5. I have a script that loops through all the uploaded files and gets each file details. Currently I am using HTML5 techniques that include FileReader. The FileReader function only works in Chrome and Firefox, so I am looking for an alternative which will work in all of the other browsers.

I saw the Stack Overflow question Flash alternative for FileReader HTML 5 API, but I wasn't able to figure how to use this Flash thing, and aren't there any other solutions so I can loop through all of the uploaded files and get each file details (which will work in Safari and Internet Explorer)?

Answer 1

Ended up not using FileReader at all, instead I looped through event.files and got each file by files[i] and sent an AJAX request by XHR with a FormData object (worked for me because I decided I don't need to get the file data):

var xhrPool = {};
var dt = e.dataTransfer;
var files = (e.files || dt.files);
for (var i = 0; i < files.length; i++) {
    var file = files[i];
    // more code...

    xhrPool[i] = getXMLHttpRequest();
    xhrPool[i].upload.onprogress = uploadProgress;
    initXHRRequest(xhrPool[i], i, file);
    data = initFormData(i, file);

    xhrPool[i].send(data);
}

function initFormData(uploaded, file) {
    var data = new FormData();
    data.append(uploaded, file);
    // parameters...

    return data;
}

function uploadProgress() {
    // code..
}

function initXHRRequest(xhr, uploaded, file) {
    // code... onreadystatechange...
    xhr.open("POST", "ajax/upload.php");
    xhr.setRequestHeader("X-File-Name", file.name);
}

function getXMLHttpRequest() 
{
    if (window.XMLHttpRequest) {
        return new XMLHttpRequest();
    }
    else {
        try {
            return new ActiveXObject("MSXML2.XMLHTTP.3.0");
        }
        catch(ex) {
            return null;
        }
    }
}
