Hi, i'm using the EasySlider 1.7 by CSSGlobe numeric version (http://cssglobe.com/post/5780/easy-slider-17-numeric-navigation-jquery-slider), in a project. When i click on a number the animation stops on the respective image, what I wanted to do is to inject another button that when pressed could restart the animation from where it stopped to the next item.

Then i've added:

(function($) {

      $.fn.easySlider = function(options){

        // default configuration properties
        var defaults = {            
            prevId:         'prevBtn',
            prevText:         'Previous',
            nextId:         'nextBtn',    
            nextText:         'Next',
            controlsShow:    true,
            controlsBefore:    '',
            controlsAfter:    '',    
            controlsFade:    true,
            firstId:         'firstBtn',
            firstText:         'First',
            firstShow:        false,
            lastId:         'lastBtn',    
            lastText:         'Last',
            lastShow:        false,                
            vertical:        false,
            speed:             800,
            auto:            false,
            pause:            2000,
            continuous:        false, 
            numeric:         false,
            numericId:         'controls'
        }; 

        var options = $.extend(defaults, options);  

        this.each(function() {  
            var obj = $(this);                 
            var s = $("li", obj).length;
            var w = $("li", obj).width(); 
            var h = $("li", obj).height(); 
            var clickable = true;
            obj.width(w); 
            obj.height(h); 
            obj.css("overflow","hidden");
            var ts = s-1;
            var t = 0;
            $("ul", obj).css('width',s*w);            

            if(options.continuous){
                $("ul", obj).prepend($("ul li:last-child", obj).clone().css("margin-left","-"+ w +"px"));
                $("ul", obj).append($("ul li:nth-child(2)", obj).clone());
                $("ul", obj).css('width',(s+1)*w);
            };                

            if(!options.vertical) $("li", obj).css('float','left');

/* <------ Replay -------------------> */
                $('#replay').click(function(){
                /* What to put here? */

                });        
/* <------ /Replay -------------------> */            
        });

    };

})(jQuery); 

There's the row with the injected button (#replay) at the beginning, and the controller at the end of the script. I've tried to reset and restart the timer, the animation restart but it slides beyond the end of all the image list... Maybe the last block sholdn't be there?

The parameters used to call the script are:

$("#slider").easySlider({
                orientation: 'horizontal',
                speed:         2000,
                auto:            true,
                pause:            2500,
                continuous:        true,
                numeric: true
            });

Any suggestion? I guess someone else have already made it
