Question

我创建了一个简单的淡入淡出滑块并使其正常工作。我想动态地将子弹导航圈合并到滑块并动态链接到幻灯片中的图像，但我发现这太难了。现在我已手动放入子弹导航圈

是的，有人能帮帮我吗？三江源

 //calculate the slide which comes after the current slide
 newSlide = sliderInt + 1; // current slide plus 1 added to variable called newSlide

 }

 function stopLoop(){
 window.clearInterval(loop); //clear interval of loop so that it does not skip images when in between intervals, ie. the 300 miliseconds just about to complete, and clicking on next will make it seem as though the you have clicked through two images 

 }

 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
 }

 $('.quickslider > img').hover(function(){
    stopLoop(); // stops the loop when image is hovered over
 },
 function(){
 startSlider(); // starts where the loop left off

我刚刚在nav-thumb的链接中添加了数据属性。单击它们时，将读取此值，幻灯片将显示图像。
