ClojureScript数组映射和按bug排序的映射？

或

3.3万，w{：idx 11}，3.3万，3.3万，3.3万，3.3万，3.3{：idx 11}，3.3{：idx 17}，3.3{：idx 20}，3.3{：idx 22}，3.3}，3.3}，n{：idx 22}，3.3{，3.3}，z，z，3{：若若上述3.3{{：idx 17}，3.3万万，3.3{{0 0 0 0 0 0，3.3万，若若如如如如如如如如上述上述上述上述上述，3万万万万万万万，，3.3万万万万万万万万万万万万，，若若若如如如如如如如如如如如如如如上述上述上述上述上述，3万万万万万万万万万万万万万万万万万万万万万万万万万，，18}，“g{:idx 0}”，l{:idx 16}，u{:idx 20}，h{:idx 10}，“m{:idx 16}”，o{:idx 11}，c{:idx 4}”

如果我们把数量限制在8就可以了

(let [mymap (into {} (for [x (shuffle (rest (clojure.string/split "abcdefghijklmnopqrstuvwxyz" #"")))]
                       {x {:idx (rand-int 24)}}))]
  (->> mymap
       (sort-by (fn [[_ m]] (:idx m)))
       (into (array-map))))

{“z{:idx 1}”，q{:idx 6}，n{:idx 7}，s{:idx 7}，f{:idx 9}，d{:idx 17}，w{:idx 18}，e{:idx 21}

可能与

您使用的clojurescript版本有关？cljs 0.0-3308中的第一个表单保持您期望的排序顺序：

(let [mymap (into {} (for [x (shuffle (rest (clojure.string/split "abcdefghijklmnopqrstuvwxyz" #"")))]
                       {x (rand-int 24)}))]
  (into (sorted-map-by (fn [k1 k2]
                         (compare [(get mymap k1) k1]
                                  [(get mymap k2) k2])))
        (take 8 mymap)))

您使用的是早于2411的版本吗？这是第一个版本，包括对您链接的问题的答案中解释的问题的修复。它是在2411版本中首次发布的版本上修复的。

问题是什么？是一个大问题。

(let [mymap (into {} (for [x (shuffle (rest (clojure.string/split "abcdefghijklmnopqrstuvwxyz" #"")))]
                       {x (rand-int 24)}))]
  (into (sorted-map-by (fn [k1 k2]
                         (compare [(get mymap k1) k1]
                                  [(get mymap k2) k2])))
        (take 8 mymap)))

    (println *clojurescript-version*) ;=>  "0.0-3308"

    (let [mymap (into {} (for [x (shuffle (rest (clojure.string/split "abcdefghijklmnopqrstuvwxyz" #"")))]
                           {x {:idx (rand-int 24)}}))]
      (into (sorted-map-by (fn [k1 k2]
                             (compare [(get-in mymap [k1 :idx]) k1]
                                      [(get-in mymap [k2 :idx]) k2])))
            mymap))
    ;=> {"d" {:idx 0}, "i" {:idx 0}, "w" {:idx 5}, "n" {:idx 6}, "q" {:idx 9}, "y" {:idx 9}, "k" {:idx 10}, "m" {:idx 10}, "x" {:idx 10}, "c" {:idx 12}, "h" {:idx 12}, "l" {:idx 13}, "v" {:idx 14}, "s" {:idx 15}, "z" {:idx 16}, "j" {:idx 17}, "p" {:idx 17}, "t" {:idx 17}, "o" {:idx 18}, "r" {:idx 19}, "b" {:idx 20}, "e" {:idx 20}, "a" {:idx 21}, "f" {:idx 21}, "g" {:idx 22}, "u" {:idx 23}}
