Example

The following code adds an onclick handler to every submit button and thus replaces the default handler in order to send the form via Ajax:

require(["aps/query", "dojo/request", "dojo/dom-form", "dojo/dom-construct", "dojo/dom-style"],
   function(query, request, domForm, domConstruct, domStyle){
      query("input[type='submit']").on("click", function(e){
         e.preventDefault(); // prevent sending the form
         var btn = e.target;
         request.post("http://example.com/", {
            data: domForm.toObject(btn.form)
         }).then(function(response){
            // replace the form with the response
            domConstruct.create(div, {innerHTML: response}, btn.form, "after");
            domStyle.set(btn.form, "display", "none");
         });
      });
});
