javascript - 引导轮播不工作和初始化

问题描述

请有人可以分析下面的代码并告诉我为什么轮播不工作。即使我单击下一步或 perv glyphicon，图片也不会滑动。我希望它是自动的。它在任何浏览器中都不起作用。我从一个网站上获取了这段代码，它在那里完美地工作，但在我的笔记本电脑上却没有。我无法理解问题出在哪里

 .colht{
    height:200px;
    border: 5px solid red;
    }
    .colht1{
    height:100px;
    border: 5px solid yellow;
    }
    .navbar-custom {
        background-color:#ffffff;
        color:#ffffff;
        border-radius:0;
    	padding:10px;
    }
