ionic 4-在ion-tab-bar中使用routerLink

Question

我需要使用routerLink创建离子选项卡。在组件ts中动态定义了nextChapterLink。
离子4选项卡已更改，我不知道如何实现我想要的。有什么想法吗？

谢谢

toList' :: BETree -> ([Float], [Char])
toList' (Leaf x) = ([x],[])   -- easy, since Leaf contains only one Float
toList' (Node a l r) =        -- Nodes are harder
  let (fl1, cl1) = toList' l  -- lists from the left branch
      (fl2, cl2) = toList' r  -- lists from the right branch
  in  (fl1 ++ fl2, cl1 ++ [a] ++ cl2)   -- combine with our Char "a"
