clojure - 打嗝代码没有响应没有(做(每个级别的html5

Question

当我使用具有 for 循环的嵌套 let 语句时，如果没有 (do (html5 ..))，我将无法运行内部 [:tr]。

(defpartial column-settings-layout [& content]

  (html5
    [:head
     [:title "my-noir-proj"]
            (include-css "assets/css/bootstrap.css")
     ]
    [:body
     [:div
      [:div
      [:image {:src "assets/img/ceva.gif" :alt "ceva-logo"}]
        (toolbar)
        ]
     [:div {:style "overflow: auto; overflow-x: hidden"}
          content]      
      [:form {:id "col_settings_form" :name "col_settings_form" :method="post" :enctype="multipart/form-data"}
       [:input {:type "button" :value "Save" :onclick "ajaxWithSerialize('save_cols_response_div','/save_cols_settings',$(col_settings_form).serialize());"}]
       [:table {:class "table-striped" :border "1"}

            [:tr [:td {:id "processing_status" }  ][:td {:id "save_cols_response_div" :colspan 6}  ]]
            [:tr [:td ][:td {:colspan "3"} "SP" ] [:td {:colspan "3"} "WP"]]
            (let [wp_settings (session/get :wp_settings)
                 sp_settings (session/get :sp_settings)]

                (do (html5 [:tr [:td {:colspan "7"} "jhyghjghj"]]))
                    (for [col (:all_cols (session/get :setting_doc))]
                      (let

                         wp_editable (:editable (field_nm (dest_station wp_settings)))

                         ]   
                        (do (html5 [:tr[:td "sfsdfgfds"]]

Answer 1

你的问题很可能是你试图做类似的事情

[:tr (for ... [:td .])]

导致打嗝格式无效

[:tr [[:td ..] [:td ..] ..]] ; note the vector of vectors inside the :tr

打嗝的地方

[:tr [:td ..] [:td ..] ..] ; :td vectors are direct elements of :tr

要获得预期的格式，您需要像

(into [:tr] (for ... [:td .]))

更新:您的 (html..) 构造也解决了这个问题的原因是它将格式化的 hiccup 标记的整个序列变成了单个 HTML 字符串。您可以删除 do - 它没有做任何有用的事情。
