Question

我看到很多像这样的代码：

(defn simple-component []
  [:div
   [:p "I am a component!"]
   [:p "This component has two paragraphs"]])

有没有办法让该组件只有两个p元素，没有封闭的div？

似乎＆＃34;菜鸟错误＆＃34;。请查看此Wiki页面：Form-1：一个简单的功能 https://github.com/Day8/re-frame/wiki/Creating-Reagent-Components

您可以使用可通过两种方式创建的react片段来做到这一点：

带有js数组（带有react元素）：

(defn simple-component []
      #js [(r/as-element [:p "I am a component!"])
           (r/as-element [:p "This component has two paragraphs"])])

带有[:<> ... ]标签（采用打h形式）：

(defn simple-component []
      [:<>
          [:p "I am a component!"]
          [:p "This component has two paragraphs"]])
