Question

您好，我想制作一个视频滑块，它 1. 上一个完成后转到下一个视频，2. 可以在任何视频之间切换，3. 有一个下一个和上一个按钮。

我从 w3 中找到了 this 图像滑块和 this 视频滑块，并尝试将它们组合起来。

它并没有完全奏效。即使视频 1 设置为自动播放，视频也不会开始播放。我不知道如何添加填充视频来展示确切的问题，但基本上视频的缩略图就像图像一样（就像图像滑块应该的那样），唯一的问题是视频不会开始，也不会播放视频结束后转到下一个。

var slideIndex = 1;
showSlides(slideIndex);

function plusSlides(n) {
  showSlides(slideIndex += n);
}

function currentSlide(n) {
  showSlides(slideIndex = n);
}

function showSlides(n) {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("dot");
  if (n > slides.length) {slideIndex = 1}    
  if (n < 1) {slideIndex = slides.length}
  for (i = 0; i < slides.length; i++) {
      slides[i].style.display = "none";  
  }
  for (i = 0; i < dots.length; i++) {
      dots[i].className = dots[i].className.replace(" active", "");
  }
  slides[slideIndex-1].style.display = "block";  
  dots[slideIndex-1].className += " active";
}
</script>

<script>
var video1 = document.getElementById('video1');
var video2 = document.getElementById('video2');
var video3 = document.getElementById('video3');
var video4 = document.getElementById('video4');
var video5 = document.getElementById('video5');
var video6 = document.getElementById('video6');
var imagen1 = document.getElementById('imagen1');

function imgTransition(){
    video1.play();
    showSlides(slideIndex += n);
}
video1.onended = function(){
    video2.play();
    showSlides(slideIndex += n);
}
video2.onended = function(){
    video3.play();
    showSlides(slideIndex += n);
}
video3.onended = function(){
    video4.play();
    showSlides(slideIndex += n);
}
video4.onended = function(){
    video5.play();
    showSlides(slideIndex += n);
}
video5.onended = function(){
    video6.play();
    showSlides(slideIndex += n);
}
video6.onended = function(){
    video1.play();
    showSlides(slideIndex += n);
}
