Implement Jquery viewport on ipad

Question

Recently I have implemented a ebook like function web app runs on ipad . One function is to make a viewport to drag the book. I used this viewport plugin (with demo) : http://borbit.github.com/jquery.viewport/

The problem is the content can not drag .This work perfectly on desktop but not ipad. There are two level of the ebook , the low level is a book page. when user click on the book, a overlay (top level) is display and it is an larger div for dragging. I suspect ipad can not swift the higher level div. Is there any way to implement the viewport (refer to the example in above link) in ipad? Thanks

<div id="view" style="height: 385px; width: 1422px; position: relative; overflow: hidden; display: block;">
<div class="viewportBinder" style="position: absolute; overflow: hidden; height: 2541px; top: -1078px; width: 1247px; left: 88px;">
<div class="viewportContent ui-draggable" style="position: absolute; height: 1463px; width: 1247px; top: 329.98150634765625px; left: 0px;">
<div id="popup" style="height: 1463px; width: 1247px; display: block;"><img id="largeText" src="http://203.80.1.28/FlippingBook/development/demo/original/Web081112_P001_text.png"><img id="largeImg" src="http://203.80.1.28/FlippingBook/development/demo/original/Web081112_P001_image.jpg">

I think this can be easily solved using jQuery UI Touch Punch, this plugin adds touch event support for jQuery UI.

Try adding the script before the viewport script but after UI script, for example:

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.10/jquery-ui.min.js"></script>   
<script type="text/javascript" src="jquery.ui.touch-punch.js"></script>
<script type="text/javascript" src="jquery.viewport.js"></script>
<script type="text/javascript" src="https://github.com/borbit/jquery.scraggable/raw/master/jquery.scraggable.js"></script>

and that's all!
