我的图像轮播不起作用？ (HTML & CSS)

问题描述

我正在尝试为网站制作图像轮播，我将其编码在括号中，括号中的实时预览显示它如下所示：[

]

然而，当我通过点击我的 index.js 在 Chrome 中打开它时，它使第一张图像决定不出现，而第二张图像出现。

当我将代码上传到github网站并完全刷新它时。它看起来像这样 [

]

它甚至不在我为它编码的容器中。

当我点击箭头时，它会将我带到下一张照片，显示为 [

]

就好像它甚至没有创建容器并将图像插入其中..

我的代码如下：

var slideIndex = 1;
showSlides(slideIndex);

// Next/prevIoUs controls
function plusSlides(n) {
  showSlides(slideIndex += n);
}

// Thumbnail image controls
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";
    
    
}

    transform: none;
  }

谁能帮帮我！？

解决方法

您的源代码没问题，只需重新检查您的图像路径文件。否则把github上的数据彻底抹掉，然后重新上传。

    var slideIndex = 1;
showSlides(slideIndex);

// Next/previous controls
function plusSlides(n) {
  showSlides(slideIndex += n);
}

// Thumbnail image controls
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";
    
    
}
