Handling Json Form With Jquery On Google App Engine

I am having some problems with making jQuery work on GAE python 2.7 . The main problem is jQuery cant catch the json data returned by the server. A simple comment form with nothing

Solution 1:

You need to cancel the default action of the form, which is to submit (which cancels any running JavaScript AJAX query in progress):

$("#submit").click(function() {
    $.ajax({
     dataType: 'json',
     beforeSubmit: function() {
     },
     timeout: 60000,
     error: function(request,error) {
     },
      success: function(data) {
       var obj = jQuery.parseJSON(data);
       //blah blah...
       } // End success
    }); // End ajax methodreturnfalse; // Cancel default action.
});

By returning false from the click handler, the normal form action, which is for the browser to submit the data to the URL named in the action attribute, is not executed.
