Get the current page number using turn js
<p>I am using turn js , a js that create flip book function. </p>

<p>From the online source the statement to get current page is :</p>

<pre><code>alert($('selector').turn('page'));
</code></pre>

<p>However, it only get a null value that means the $('selector').turn('page') is not working. How to get the page no of the user reading page. Since a book have 2 page at the same time, I would like to get the page either left hand side or right hand side, How to do this ? Thanks </p>
