Question

我必须为四个不同的div部分调用滑块脚本（即）我的页面有四个滑块。它仅适用于第一个滑块。需要为所有滑块div部分重用该脚本。现在所有滑块都被视为单个滑块。

＆＃13;

var slideIndex = 1;
showDivs(slideIndex);

function plusDivs(n) {
  showDivs(slideIndex += n);
}

function currentDiv(n) {
  showDivs(slideIndex = n);
}

function showDivs(n) {
  var i;
  var x = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("demo");
  if (n > x.length) {slideIndex = 1}
  if (n < 1) {slideIndex = x.length}
  for (i = 0; i < x.length; i++) {
     x[i].style.display = "none";
  }
  for (i = 0; i < dots.length; i++) {
     dots[i].className = dots[i].className.replace(" w3-red", "");
  }
  x[slideIndex-1].style.display = "block";
  dots[slideIndex-1].className += " w3-red";
}

.mySlides {display:none}

Answer 1

我知道这会很丑陋，但复制一个新的例子：Myslide1是第一个滑块，第二个是Myslide2。因为你说Myslide的img应该改变....是的，有多个Myslides。

滑块不能在多个div中工作
