this.prepend($clone);
this.width($width*2);
$inter=
setInterval(function(){

$marginleft=
parseInt($marginleft);
$childh=
parseInt($this.children().width());
if(Math.abs($marginleft)>=$width){
$this.css('margin-left',"0px");
}else{
$this.css('margin-left',$marginleft-1+"px");
}
},settings.s);
this.on('mouseover',function(){
clearInterval($inter);
});
this.on('mouseout',function(){
$inter=setInterval(function(){
$marginleft=$this.css('margin-left');
$marginleft=
parseInt($marginleft);
$childh=
parseInt($this.children().width());
if(Math.abs($marginleft)==$width){
$this.css('margin-left',"0px");
}else{
$this.css('margin-left',$marginleft-1+"px");
}
},settings.s);
});
};
}( jQuery ));

当子元素不比父元素宽时，不会发生滚动。

使用

$('.foo').ilscroll()

一个参数s用于控制速度.

修改用于应对margin-auto
