I'm trying to write a page that interacts with the server via AJAX. The Javascript seems to work to a limited extent, but it receives no response from the server. Also, the dev_appserver.py window doen't show any interaction when the javascript shold be submitting and receiving things.

Javascript functions:

<script type="text/javascript">

function bodyUpdate(tab) {//v1.0 var request; try { request = new XMLHttpRequest(); } catch (trymicrosoft) { try { request = new ActiveXObject("Msxml2.XMLHTTP"); } catch (othermicrosoft) { try { request = new ActiveXObject("Microsoft.XMLHTTP"); } catch (failed) { request = false; } } }

if (!request) alert("Error initializing XMLHttpRequest!");

var url = "/main/" + escape(tab); request.open("GET", url, true); request.onreadystatechange = updatePage(); request.send(null);

}

function updatePage() { var loading = '<p class="style1"><span class="style3"><strong>Loading...</strong></span></p>'; var finished = '<p class="style1"><span class="style3"><strong>Finished</strong></span></p>';

document.getElementById("body").innerHTML = loading; if (request.readyState == 4) { if (request.status == 200) { var response = request.responseText; document.getElementById("body").value = response; } else alert("status is " + request.status); }

}

</script>

Python:

class UpdateNextActions(webapp.RequestHandler): def get(self): tasks = database.Task.all() if users.get_current_user(): tasks.filter('creator =', users.get_current_user()) tasks.order('date') template_values = {'tasks':tasks} path = os.path.join(os.path.dirname(__file__), 'NextActionsTemp.htm') self.response.out.write(template.render(path, template_values)) else: self.redirect('/')

All help is appreciated.
