I wanted to have the amount of clicks stored in the Torage locale, and when I returned the number of clicks continued where it left off. I tried to do so, but no alert only shows NaN:

        document.body.appendChild(p);

    $(document).ready(function(){

         var cout = localStorage.getItem('cout') || 0;

            $("#btnCount").click(function(){
                cout = parseInt(cout)+1;
                $('p').html(cout);
                alert(cout);
                localStorage.setItem('cout',cout);
            });         
    });    
    </script>
    <button type="button" id="btnCount">Click me</button>

   <script type="text/javascript">
        var p = document.createElement("p");
        p.setAttribute('id','num');
        document.body.appendChild(p);

    $(document).ready(function(){


        cout = localStorage.getItem('cout');
        cout = parseInt(cout) || 0; 

            $("#btnCount").click(function(){
                cout = cout+1;
                $('p').html(cout);
                // alert(cout);
                localStorage.setItem('cout',cout);
            });         
    });
