AJAX post call with JSON data

Guys,

What is the proper way to make an ajax post call to an url with jsonData like

{ "my_name": "superman" }

Right now I'm using something like

Ajax post ->

tag - foo

url - myurl/parser.php

data - ""

Which obviously means my parser.php needs to reconstruct that url into a json.

Is there a better way?

thanks,

Alrightly, found it.. sending jsons via variables.

Thanks :)
