$(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');
  });

  $('#myCarousel').bind('slid', function() {
    // Get currently selected item
    var item = $('#myCarousel .carousel-inner .item.active');

    // Deactivate all nav links
    $('#myCarousel .nav li').removeClass('active');

    // Index is 1-based, use this to activate the nav link based on slide
    var index = item.index() + 1;
    $('#myCarousel .nav li:nth-child(' + index + ')').addClass('active');
  });
});
#myCarousel .nav a small {
  display: block;
}
#myCarousel .nav {
  background: #eee;
}
.nav-justified > li > a {
  border-radius: 0px;
}
.nav-pills>li[data-slide-to="0"].active a {

我包含的jQuery文件

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

问题是我的滑块活动标签不会改变.第一个选项卡始终处于活动状态,顶部滑块保持不变.如果有人可以帮我,请

最佳答案 请将轮播收听的事件从滑动更改为slid.bs.carousel

$(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');
  });

  $('#myCarousel').on('slid.bs.carousel', function() {
    // Get currently selected item
    
    var item = $('#myCarousel .carousel-inner .item.active');

    // Deactivate all nav links
    $('#myCarousel .nav li').removeClass('active');

    // Index is 1-based, use this to activate the nav link based on slide
    var index = item.index() + 1;
    $('#myCarousel .nav li:nth-child(' + index + ')').addClass('active');
  });
});
#myCarousel .nav a small {
  display: block;
}
#myCarousel .nav {
  background: #eee;
}
.nav-justified > li > a {
  border-radius: 0px;
}
.nav-pills>li[data-slide-to="0"].active a {
  background-color: #16a085;
}
.nav-pills>li[data-slide-to="1"].active a {
  background-color: #e67e22;
}
.nav-pills>li[data-slide-to="2"].active a {
  background-color: #2980b9;
}
.nav-pills>li[data-slide-to="3"].active a {
  background-color: #8e44ad;
}
