使用下一个/上一个按钮在我现有的滑块中添加导航项目符号

Question

我有一个带有下一个/上一个按钮的简单视频滑块。事实证明，每个视频幻灯片的单独项目符号导航也是需要的。

这让我来到这里与你们打招呼。

这是我展示我所做的可悲的努力：-

我就是这样做的。

最好的。

function showSlide(id){ // id is the variable name of what we will be calling which will be passed
    stopLoop(); // call function that we have declared above so that the interval is cleared and restarted

        if(id > count){
            id = 1; // if id = more than the count of images then set back to 1
        }else if(id < 1){
            id = count; // if id = less than count of list then set back to 4 or whatever number of images
        }

        $('.quickslider > img').fadeOut(300); // fadeout all images
        $('.quickslider > img#'+id).fadeIn(300); // use sliderNext to calculate the next slider id

        $('.nav-thumbs > a#'+id).addClass('active');

        sliderInt = id; // update so that the current slide = 2 as set globally
        sliderNext = id + 1; // calculate the next image
        startSlider(); // start the slider process again, as it was stopped before
}
