form-3组件不重新呈现任何内容，即使调用了component -did-update

Question

我有以下代码来测试form-3组件：

(defn inner [data]
  (reagent/create-class
   {:display-name "Counter"

    :component-did-mount (fn []
                           (js/console.log "Initialized")
                           [:h1 "Initialized! " data])


    :component-did-update (fn [this _]
                            (let [[_ data] (reagent/argv this)]
                              (js/console.log (str "Updated " data))
                              [:div (str "My clicks " data)]))

    :reagent-render (fn [] [:div (str "My clicks " data)])}))

我能够成功地触发:component-did-mount和:component-did-update，因为控制台日志中有预期的输出。然而，这两个函数实际上都没有改变页面上的任何内容。它只显示整个时间内[:div (str "My clicks " data)]的初始状态。

我做错了什么？Ps。我已经读过reagent docs和purelyfunctional guide了。

您必须在:reagent-render函数中使用repeat the parameters：

(fn [data] [:div (str "My clicks " data)])
