            //$("#slider").mySlider();
        });
   </script>

It says mySlider is not defined

please help me to solve this. Thanks

It is not defined, since you did not define it.

You defined only $.fn.mySlider

You may want something like this, to have a separate function:

var mySlider = function() {
    $("#slider").mySlider();
};
