javascript - 调整简单 slider

Question

我正在使用这个非常基本的 slider ，它可以正常工作 - 但是当页面上有多个 slider 时，当单击左右按钮中的一个时，它们会同时滑动。

如何使每一个都独一无二？

感谢任何帮助

谢谢

可在此处找到工作示例 -> https://codepen.io/zuraizm/pen/vGDHl <-

jQuery(document).ready(function ($) {
  $('#checkbox').change(function(){
    setInterval(function () {
      moveRight();
    }, 3000);
  });

  var slideCount = $('#slider ul li').length;
  var slideWidth = $('#slider ul li').width();
  var slideHeight = $('#slider ul li').height();
  var sliderUlWidth = slideCount * slideWidth;

  $('#slider').css({ width: slideWidth, height: slideHeight });
  $('#slider ul').css({ width: sliderUlWidth, marginLeft: - slideWidth });
  $('#slider ul li:last-child').prependTo('#slider ul');

  function moveLeft() {
    $('#slider ul').animate({
      left: + slideWidth
    }, 200, function () {
      $('#slider ul li:last-child').prependTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  function moveRight() {
    $('#slider ul').animate({
      left: - slideWidth
    }, 200, function () {
      $('#slider ul li:first-child').appendTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  $('a.control_prev').click(function () {
    moveLeft();
  });

  $('a.control_next').click(function () {
    moveRight();
  });

});

您的所有代码都基于 HTML id 属性寻址元素，这些属性对于页面上的单个元素应该是唯一的。

既然您已经在使用 jQuery，我建议您继续阅读关于构建您的函数作为 plugin 的一部分的内容。可以应用于页面上的多个元素。
