Another One (Just because I have it hosted on my website)

This is a plugin I used as an image slider on my website. It is pretty awesome because you can use it on mobile browsers with no issues at all. The actual plugin looks like:


(function($){
 $.fn.jslider=function(o){
  o=$.extend({
   btnPrev:null,
   btnNext:null,
   btnGo:null,
   mouseWheel:false,
   auto:false,
   speed:1800,
   easing:null,
   vertical:false,
   circular:true,
   visible:1,
   start:0,
   scroll:1,
   beforeStart:null,
   afterEnd:null},
   o||{});
  
  return this.each(function(){
   var b=false,
   animCss=o.vertical?"top":"left",
   sizeCss=o.vertical?"height":"width";
   var c=$(this),
   ul=$("ul",c),
   tLi=$("li",ul),
   tl=tLi.size(),
   v=o.visible;
  
  if(o.circular){
   ul.prepend(tLi.slice(tl-v-1+1).clone()).append(tLi.slice(0,v).clone());
   o.start+=v}var f=$("li",ul),
   itemLength=f.size(),
   curr=o.start;
   c.css("visibility","visible");
   f.css({overflow:"hidden",float:o.vertical?"none":"left"});
   
   ul.css({
    margin:"0",
    padding:"0",
    position:"relative",
    "list-style-type":"none",
    "z-index":"1"});
    
    c.css({
     overflow:"hidden",
     position:"relative",
     "z-index":"2",
     left:"0px"});
     
    var g=o.vertical?height(f):width(f);
    var h=g*itemLength;
    var j=g*v;f.css({
     width:f.width(),
     height:f.height()});
    
    ul.css(sizeCss,h+"px").css(animCss,-(curr*g));
    c.css(sizeCss,j+"px");
   
   if(o.btnPrev)$(o.btnPrev).click(function(){
    return go(curr-o.scroll)});
   
   if(o.btnNext)$(o.btnNext).click(function(){
    return go(curr+o.scroll)});if(o.btnGo)$.each(o.btnGo,function(i,a){
     $(a).click(function(){
      return go(o.circular?o.visible+i:i)}
     )});
     
   if(o.mouseWheel&&c.mousewheel)c.mousewheel(function(e,d){
    return d>0?go(curr-o.scroll):go(curr+o.scroll)});
    
   if(o.auto)setInterval(function(){go(curr+o.scroll)},o.auto+o.speed);
   
   function vis(){
    return f.slice(curr).slice(0,v)};
    function go(a){if(!b){
     if(o.beforeStart)o.beforeStart.call(this,vis());
     if(o.circular){if(a<=o.start-v-1){
      ul.css(animCss,-((itemLength-(v*2))*g)+"px");
      curr=a==o.start-v-1?itemLength-(v*2)-1:itemLength-(v*2)-o.scroll
     }else if(a>=itemLength-v+1){ul.css(animCss,-((v)*g)+"px");
      curr=a==itemLength-v+1?v+1:v+o.scroll}else curr=a
     }else{if(a<0||a>itemLength-v)return;else curr=a}
     b=true;
     
     ul.animate(animCss=="left"?{left:-(curr*g)}:{top:-(curr*g)},o.speed,o.easing,function(){
      if(o.afterEnd)o.afterEnd.call(this,vis());
      b=false});
      if(!o.circular){$(o.btnPrev+","+o.btnNext).removeClass("disabled");
      $((curr-o.scroll<0&&o.btnPrev)||(curr+o.scroll>itemLength-v&&o.btnNext)||[]).addClass("disabled")}}
     return false}})};
     
     function css(a,b){return parseInt($.css(a[0],b))||0};function width(a){
      return a[0].offsetWidth+css(a,'marginLeft')+css(a,'marginRight')};
     
     function height(a){return a[0].offsetHeight+css(a,'marginTop')+css(a,'marginBottom')}})
     
(jQuery);
This pretty much sets the margins, size etc of the scroll box for your images that you place using html. The demo of it is on my "Work" page here:

and I got this groovy tutorial from this YouTube video.
