jQuery SerialScroll：将类添加到活动项

I'm using Ariel Flesler's serialScroll script and would like to add a class to the active, or highlighted item so I can style it with CSS. Reading the documentation I discovered the notify trigger, but I'm not sure how / if it could be used to accomplish this.

我正在使用Ariel Flesler的serialScroll脚本，并希望将一个类添加到活动或突出显示的项目中，以便我可以使用CSS设置它。阅读文档我发现了通知触发器，但我不确定如何/是否可以用它来完成此操作。

This is my code:

jQuery(function( $ ){

    $('#slideshow').serialScroll({
        items:'li',
        prev:'#screen2 a.prev',
        next:'#screen2 a.next',
        offset:-180,
        start: 0,
        duration:1200,
        force:true,
        stop:true,
        lock:false,
        cycle:false,
        jump: true
    });

});

        </ul>
    </div>
</div>

Am I misunderstanding the function of the notify trigger? And if so, is there any alternate ways of accomplishing what I'm after?

我误解了通知触发器的功能吗？如果是这样，有没有其他方法可以完成我追求的目标？

From the plugin example page, here's how onBefore is being used:

从插件示例页面，这里是如何使用onBefore：

onBefore:function( e, elem, $pane, $items, pos ){
    /**
    * 'this' is the triggered element 
    * e is the event object
    * elem is the element we'll be scrolling to
    * $pane is the element being scrolled
    * $items is the items collection at this moment
    * pos is the position of elem in the collection
    * if it returns false, the event will be ignored
    */
    //those arguments with a $ are jqueryfied, elem isn't.
}

in that function, you can add your active class, and use the onAfter function to remove the class from the previous element.

在该函数中，您可以添加活动类，并使用onAfter函数从上一个元素中删除该类。
