title: Clojure (Hiccup): How can I know which submit button got pressed in a form?
body: <p>I have a form, using hiccup framework. It looks like this:</p>
  
  <pre><code>(form-to {:enctype "multipart/form-data"}
    [:post "/add-data"]
  
    ...
  
    (submit-button {:class "btn"} "Save")
    (submit-button {:class "btn} "Clone"))
  </code></pre>
  
  <p>How do I know which submit button got pressed, <em>without</em> using jQuery/javascript?</p>
  
  <p>I looked at the Hiccup's documentation for <code>request</code>. But, the <code>request</code> element does not have a lot of documentation.</p>
