jQuery.post()

jQuery.post()

When I tried this:

$.post("http://www.google.com/loc/json", request, function(response) {
   MochiKit.Logging.log(response);
}, "json");

I really got expected response from Google's server according to a monitor software capturing packets and frames. However, the variable "response" is null and it says "Failed to load resource" in Javascript Console in Google Chromium. Could anyone help me?
