带标签的滑块旋转木马不在bootstrap 4中工作

标签： jquery html css twitter-bootstrap bootstrap-4

我尝试实现此代码： https://bootsnipp.com/snippets/featured/tabbed-slider-carousel

唯一的区别：我正在使用这些导入：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<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>

这是我的代码：

HTML 

<div class="container">
    <div id="myCarousel" class="carousel slide" data-ride="carousel">

    <ul class="nav nav-pills nav-justified">
          <li data-target="#myCarousel" data-slide-to="0" class="active"><a href="#">About<small>Lorem ipsum dolor sit</small></a></li>
          <li data-target="#myCarousel" data-slide-to="1"><a href="#">Projects<small>Lorem ipsum dolor sit</small></a></li>
          <li data-target="#myCarousel" data-slide-to="2"><a href="#">Portfolio<small>Lorem ipsum dolor sit</small></a></li>
          <li data-target="#myCarousel" data-slide-to="3"><a href="#">Services<small>Lorem ipsum dolor sit</small></a></li>
        </ul>

      <!-- Wrapper for slides -->
      <div class="carousel-inner">

        <div class="item active">
          <img src="http://placehold.it/1200x400/cccccc/ffffff">
           <div class="carousel-caption">

      </div><!-- End Carousel Inner -->





    </div><!-- End Carousel -->
</div>

JS：

$(document).ready( function() {
    $('#myCarousel').carousel({
        interval:   4000
    });

    var clickEvent = false;
    $('#myCarousel').on('click', '.nav a', function() {
            clickEvent = true;
            $('.nav li').removeClass('active');
            $(this).parent().addClass('active');        
    }).on('slid.bs.carousel', function(e) {
        if(!clickEvent) {
            var count = $('.nav').children().length -1;
            var current = $('.nav li.active');
            current.removeClass('active').next().addClass('active');
            var id = parseInt(current.data('slide-to'));
            if(count == id) {
                $('.nav li').first().addClass('active');    
            }
        }
        clickEvent = false;
    });
});

的CSS：

body { padding-top: 20px; }
#myCarousel .nav a small {
    display:block;
}
#myCarousel .nav {
    background:#eee;
}
#myCarousel .nav a {
    border-radius:0px;
}

请查看此jsfiddle中的结果：https://jsfiddle.net/2ku1jhk9/1/

在那里你可以看到，它以某种方式不起作用。但我在控制台中没有收到任何错误。所以我无能为力。

有谁知道为什么它不能用于bootstrap 4以及我需要改变什么？

答案 0 :(得分：3)

代码变化较小的Bootstrap4轮播。所有轮播项目类别应从item更改为carousel-item。看一下代码

<div class="item">

应更改为

<div class="carousel-item">

＆＃13;
＆＃13; 
$(document).ready( function() {
    $('#myCarousel').carousel({
		interval:   4000
	});
	
	var clickEvent = false;
	$('#myCarousel').on('click', '.nav a', function() {
			clickEvent = true;
			$('.nav li').removeClass('active');
			$(this).parent().addClass('active');		
	}).on('slid.bs.carousel', function(e) {
		if(!clickEvent) {
			var count = $('.nav').children().length -1;
			var current = $('.nav li.active');
			current.removeClass('active').next().addClass('active');
			var id = parseInt(current.data('slide-to'));
			if(count == id) {
				$('.nav li').first().addClass('active');	
			}
		}
		clickEvent = false;
	});
});
＆＃13; 
body { padding-top: 20px; }
#myCarousel .nav a small {
    display:block;
}
#myCarousel .nav {
	background:#eee;
}
#myCarousel .nav a {
    border-radius:0px;
}
