FileReader.onLoad() is not called in blackberry device


I have made an application in which user selects image file and shows that image in page.But here reader.onload() event is not called.

Below is my code.


<!DOCTYPE html>
.thumb {
height: 75px;
border: 1px solid #000;
margin: 10px 5px 0 0;

<input type="file" id="files" name="files[]" multiple />
<output id="list"></output>

function handleFileSelect(evt) {
var files = evt.target.files; // FileList object

// Loop through the FileList and render image files as thumbnails.
for (var i = 0, f; f = files[i]; i++) {

// Only process image files.
if (!f.type.match('image.*')) {

var reader = new FileReader();


// Closure to capture the file information.
reader.onload = (function(theFile) {
return function(e) {
// Render thumbnail.
var span = document.createElement('span');
span.innerHTML = ['<img class="thumb" src="', e.target.result,
'" title="', escape(theFile.name), '"/>'].join('');
document.getElementById('list').insertBefore(span, null);

// Read in the image file as a data URL.

document.getElementById('files').addEventListener('change', handleFileSelect, false);


It is not throwing any error.But still it is not working.

Please replay fast becuse it is urgent.

Re: FileReader.onLoad() is not called in blackberry device

I just ran your code (on a PlayBook running 2.0) from jsfiddle and everything looks and works fine to me.




Did you make any progress on this yourself?
