What you should do is return either a 'success' or 'failure' key in your JSON response_dict. If you're using YAHOO's library, it will then route appropriately to the success or failure method of your callback object. Take a look at James Bennett's write up about this: http://www.b-list.org/weblog/2006/07/31/django-tips-simple-ajax- example-part-1 http://www.b-list.org/weblog/2006/08/05/django-tips-simple-ajax- example-part-2 And the mimetype should be application/json, this prevents security holes from happening, see: http://jibbering.com/blog/?p=514 text/javascript is not really appropriate as json is not strictly Javascript, but a subset of Javascript.
