Bootstrap轮播无法正常显示

时间:2018-05-30 10:06:51

标签: javascript jquery html css twitter-bootstrap

我正在使用这个引导轮播:https://codepen.io/kreigd/pen/ybYNoN

我确实将这些文件复制到了我的主题,但它仍然无法正常显示,我也没有收到任何错误。这是我的代码的HTML / CSS / Javascript。

我的jQuery在我的bootstrap js之前被加载,所以这不是问题。

我无法在任何地方找到答案,所以我真的很感激帮助!

您还可以查看网站本身并检查代码:http://www.bureauvdo.jevdopilot.nl/over-ons/



$("#myCarousel").on("slide.bs.carousel", function(e) {
  var $e = $(e.relatedTarget);
  var idx = $e.index();
  var itemsPerSlide = 3;
  var totalItems = $(".carousel-item").length;

  if (idx >= totalItems - (itemsPerSlide - 1)) {
    var it = itemsPerSlide - (totalItems - idx);
    for (var i = 0; i < it; i++) {
      // append slides to end

您需要在HTML代码中加入:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>

  if (idx >= totalItems - (itemsPerSlide - 1)) {
    var it = itemsPerSlide - (totalItems - idx);
    for (var i = 0; i < it; i++) {
      // append slides to end
      if (e.direction == "left") {
        $(".carousel-item")
          .eq(i)
          .appendTo(".carousel-inner");
