Question

我刚刚编写了bootstrap carousel，但是我无法获得滚动指示符（左，右）。

请找到下面的代码段

我得到了滚动，除了右侧“指示符”之外的所有内容都没有出现

我做错了什么？

由于

添加了默认字形，并且您在右侧/下一个箭头上缺少def k_folds(k: Int, vv: Seq[Int]): Stream[Seq[Int]] = if (k > 1) vv.take((vv.size+k/2)/k) +: k_folds(k-1, vv.drop((vv.size+k/2)/k)) else Stream(vv)属性。

scala> val indices = scala.util.Random.shuffle(1 to 39)

scala> for (ff <- k_folds(7, indices)) println(ff)
Vector(29, 8, 24, 14, 22, 2)
Vector(28, 36, 27, 7, 25, 4)
Vector(6, 26, 17, 13, 23)
Vector(3, 35, 34, 9, 37, 32)
Vector(33, 20, 31, 11, 16)
Vector(19, 30, 21, 39, 5, 15)
Vector(1, 38, 18, 10, 12)

scala> for (ff <- k_folds(7, indices)) println(ff.size)

Bootstrap幻灯片（轮播）指示灯不起作用
