如何包含SlideShow和ImageComparison

Question

我想把这个剧本和脚本放在一起。另外，它的作用就像一种魅力。但出于某种原因，两者结合在一起是行不通的。

我想问题就在这里的某个地方(可能是为了纠正以前的/下一个幻灯片脚本)，但我不知道如何修复它。我可以求助吗？谢谢!

// Read photos in directory
if ($handle = opendir('src/images/')) {
$i = 0;
    while (false !== ($entry = readdir($handle))) {
        if ($entry != "." && $entry != "..") {
           $a[] = $entry;
            $i++;
        }
    }
    closedir($handle);
}

// Display photos
while ($i != 0)
{
echo '
<div class="mySlides fade">
  <div class="numbertext">1 / 3</div>
   <div class="wrapper">

  <div class="text">' . $a[$i-2]." a " . $a[$i-1]. '<br></div>

<a class="prev" onclick="plusSlides(-1)">&#10094;</a>
<a class="next" onclick="plusSlides(1)">&#10095;</a>

';
$i = $i-2;
}
?>
</div>

<div style="text-align:center">
  <span class="dot" onclick="currentSlide(1)"></span> 
  <span class="dot" onclick="currentSlide(2)"></span>
  <span class="dot" onclick="currentSlide(3)"></span> 
</div>

// Script for the previous/next slide
<script>
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>

我通过$_SESSION和$_GET方法解决了这个问题(没有上面提到的幻灯片脚本)。
