为什么我的卡旋转木马上的箭头不工作?

Question

我的卡片传送带工作有问题。我还在学习JS，但我肯定这是问题，我不知道如何解决它。每当我点击这个旋转木马的按钮/箭头，而不是滑动，它重新加载整个页面。我什么都查过了，但显然我还是漏掉了什么。下面是JS中的代码:

(function($) {
"use strict";
$('.next').click(function(){ $('.carousel').carousel('next');return false; });
$('.prev').click(function(){ $('.carousel').carousel('prev');return false; });

})(jQuery);

HTML:

<section class="container pt-3">
<div class="row">
<div class="col-lg-12">
<h1>Vesti</h1>
</div>

<section class="carousel slide" data-ride="carousel" id="postsCarousel">

请查看下面的代码链接希望它对你有用。我想你忘记在代码中添加bootstrap.min.js了。

请参考此链接:https://jsfiddle.net/yudizsolutions/xomswhnq/

$('.next').click(function(){ $('.carousel').carousel('next');return false; });
$('.prev').click(function(){ $('.carousel').carousel('prev');return false; });
