        var count_val = 0;
        $('input[name="count"]').keyup(function(){
            count_val = parseFloat($(this).val())||0;
            //console.log(count_val);
            //alert(count_val);
        });
        //alert(count_val);
        //console.log(count_val);

    }
    change_count();
    alert(count_val);

Your logic is strange, but you can just return the value you want — Paulo Lima

Your logic here is very flawed as the count_val value won't be changed until the keyup function has fired, but that will never happen until after the alert has been run, so the value will always show 0. Instead keep your logic within the keyup handler.
