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

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 .]))

làm mới: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 LÀM - 它没有做任何有用的事情。

关于clojure - 打嗝代码没有响应没有(做(每个级别的html5，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/9805177/
