滑块中的错误

Question

通过条件滑块必须固定，并通过按下按钮进行切换。单独地，所有的作品都很酷，一起 - 休息。情况是这样的......当滑块刚刚启动并出现第一张幻灯片时，切换按钮起作用。但是一旦动画完成并且第一张幻灯片被第二张幻灯片替换，它就会停止工作。更准确地说 - 如果有第二张幻灯片，那么按下第一个按钮应该首先转动，但它不起作用......并且开始工作，只有在此之前按下第二个按钮。同样对于另一张幻灯片...

  var toggle1 = document.querySelector(".slide-1");
        var toggle2 = document.querySelector(".slide-2");
        var slide1 = document.querySelector(".first");
        var slide2 = document.querySelector(".second");


        toggle1.addEventListener("click", function(event) {
          //        event.preventDefault();
          //            slide2.classList.add("display-slide-1");
          //            slide1.classList.add("display-slide-2");
          //            slide2.classList.remove("display-slide-2");
          //            slide1.classList.remove("display-slide-1");

          //            slide2.classList.add("display-2");
          //            slide1.classList.add("display-1");


          slide2.classList.add("display-slide-2");

当单击切换时，在适当的切换事件中，通过从节点元素中删除 classList 来停止两张幻灯片的动画，并显示相应的幻灯片并根据需要进行延迟，然后将动画添加到节点元素中。

这里我提供了 show slide2 的逻辑，onclick toggle-2

toggle2.addEventListener("click", function(event) {
           slide2.classList.remove("display-slide-2");
           slide1.classList.remove("display-slide-1");

         //  alert( slide2.style.zIndex +" "+  slide1.style.zIndex);
           slide1.style.left = "-620px";
           slide2.style.left = "0px";
           slide2.style.zIndex  = "2";
           slide2.style.display ="block";

            setTimeout(function(){
               slide2.classList.add("display-slide-2");
               slide1.classList.add("display-slide-1");
           },1000);  // set delay as per your need

        });

I hope this meet your expectation
