+Here's a simple recipe that worked for me. It is quite inspired by the [wiki:AjaxDojoFormSub] example―and from [http://www.b-list.org/weblog/2006/07/31/django-tips-simple-ajax-example-part-1 this tutorial]―except that this  recipe is expected to use python-cjson for receiving JSON data.
 My initial objective was to display validation errors without doing a page-refresh, by using JSON
 …
 {{{
+import cjson
+from django.http import HttpResponse
+from django.template import loader, Context
 def register(request):
+    # write the view here
+    pass
+    # Register or reports any (new)form-validation errors using JSON.
+    form = ExampleForm(request.POST)
+    t = loader.get_template('myform.html')
+    if not form.is_valid():
+       # Return JSON object containing the errors object.
+       if xhr:
+          return HttpResponse(cjson.encode(form.errors), mimetype='text/javascript')
+       else:
+          # vanilla Http response fallback
+          return HttpResponse(t.render(Context({'errors' : form.errors }))
+    else:
+       # Do something when the form has been validated.
+       ...
