jquery - 4 col 在 Bootstrap 中滚动 一个一个滚动

标签 jquery css twitter-bootstrap twitter-bootstrap-3

所以我找到了这个漂亮的 Bootstrap 样本，一个一个地滚动，运行顺利。

http://jsfiddle.net/eaae76kx/

我试图更改它，以便在开始时出现 4 个列而不是 3 个。

谁能帮我相应地调整 javascript

        $('#myCarousel').carousel({
          interval: 10000
        })

        $('.carousel .item').each(function(){
          var next = $(this).next();
          if (!next.length) {
            next = $(this).siblings(':first');
          }
          next.children(':first-child').clone().appendTo($(this));

          if (next.next().length>0) {
            next.next().children(':first-child').clone().appendTo($(this));
          }
          else {
            $(this).siblings(':first').children(':first-child').clone().appendTo($(this));
          }
        });

因为仅仅将 css 更改为 25% 并将 col-xs-4 更改为 col-xs-3 是不够的，而且我的 javascript 技能显然也不够

谢谢

最佳答案

我从我的 Angular 编辑它，观看它和我在 bootstrap 4 而不是 bootstrap 3 中制作的重要东西。

如果您想在 Bootstrap 3 中使用此代码，请在评论中询问我。

Bootstrap 4

$('#recipeCarousel').carousel({
  interval: 10000
})

$('.carousel .carousel-item').each(function(){
    var next = $(this).next();
    if (!next.length) {
    next = $(this).siblings(':first');
    }
    next.children(':first-child').clone().appendTo($(this));
    
    for (var i=0;i<2;i++) {
        next=next.next();
        if (!next.length) {
        	next = $(this).siblings(':first');
      	}
        
        next.children(':first-child').clone().appendTo($(this));
      }
});
