    这是一个创建于 1020 天前的主题,其中的信息可能已经有所发展或是发生改变。

    ''' [ "A", [ "A", "B", "C", [ "A", "B", "C" ] ], "B", "C" ] ''' 把上面的变成下面这样的,
    '''

    • A
      • A
      • B
      • C
        • A
        • B
        • C
    • B
    • C
      • 原生 js 办法是判断是否数组,是数组就创建列表,是字符串就创建子项然后迭代 但是没有找到 vue 怎么写

    @rabbbit 老哥你好,非常感谢老哥
    我有一个不情之请,就是虽然我很不想当伸手党,但我现在的水平实在跑不动上面的代码,方便给一个浏览器能跑的例子吗?
    谢谢老哥,下面是我自己写的,没有跑通
