        forceRedraw : function(element) {
            if (!element) { return; }
            var n = document.createTextNode(' '),
                position = element.style.position;
            element.appendChild(n);
            element.style.position = 'relative';
            setTimeout(function(){
                element.style.position = position;
                n.parentNode.removeChild(n);
            }, 25);
        }

    }

    $.fn.catslider = function( options ) {
        var instance = $.data( this, 'catslider' );
        if ( typeof options === 'string' ) {
            var args = Array.prototype.slice.call( arguments, 1 );
            this.each(function() {
                instance[ options ].apply( instance, args );
            });
        }
        else {
            this.each(function() {
                instance ? instance._init() : instance = $.data( this, 'catslider', new $.CatSlider( options, this ) );
            });
        }
        return instance;
    };

} )( jQuery, window );

我尝试了以下

<script src="js/item_slider/jquery.catslider.js"></script>
<script>
$(function() {
$('#mi-slider').catslider(          
setInterval(function() {$('#mi-slider nav > a').trigger('click');}, 2500)
);
}); 
</script>

但它只能在第二个和第一个导航之间切换。

自动滑动：不干净，但对我有用。jquery.catslider.js LINE 49（之后：var self = this;）添加：

var changeTime = 5000;
 var actualCat = 0
 setInterval(function() {
 self.showCategory(actualCat);

 if(actualCat < $('#mi-slider ul').length - 1) {
     actualCat++;
 }else {
 actualCat = 0;
 }
 }, changeTime);
