[Python] How to upload a file and show progress bar in Django?

I have written code to upload a file in Django as follows:

def upload(request):
if request.method == 'POST':
form = UploadFileForm(request.POST, request.FILES)
if form.is_valid():
handle_uploaded_file(request.FILES['file'])
return render_to_response('uploadsuccess.html')
else:
form = UploadFileForm()
return render_to_response('upload.html', {'form': form})


def handle_uploaded_file(f):
filename = "/media/Data/static/Data/" + f.name
destination = open(filename, 'wb+')
for chunk in f.chunks():
destination.write(chunk)
destination.close()


The code works fine for me. However, I don't know how should I modify this code to show a progress bar on the client side.

My html page looks like:

{% extends "index_base.html" %}

{% block content %}
<script src="/media/js/functions.js" type="text/javascript"></script>
<script src="/media/js/jquery.js" type="text/javascript">
</script>
<div id="main_container">

{% include "includes/nav.html" %}

<!------- Main Contents ---------->
<div id="contents_holder">
<div id="contents">
<div id="c_banner">
<span class="main_title">Upload File</span>
</div>
<div id="setting">
<form name="post" action="/upload.psp/" method="post" enctype="multipart/form-data">
<h2>Upload File</h2></br>
<p>{{ form.file.label_tag }}&nbsp;&nbsp;{{ form.file }}</p></br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<input type="submit" value="Upload" name="uploadButton" />
&nbsp;&nbsp;<input type="button" value="Cancel" name="cancelUploadButton" onclick ="cancelUploadClicked()"/>
<input type="hidden" value="title" name="title" id="title" />
</form>
</div>

</div>
</div>
</div>

<!------- Main Contents Finished ---------->
{% endblock %}


Can anybody help me integrate Upload progress bar with this code?

Thanks in advance.
