jQuery Ajax maintain POST Html notation

Is it possible to maintain the Php post notation using a Ajax Post. For example, if I do a standard post using a HTML form and var_export the $_POST data I can see the structure of any array data. I'd like to maintain this when using a Ajax Post, I've tried using jQuery serialise and serialiseArray but these don't maintain th开发者_运维知识库e same format.

This should work like a charm:

$.post("test.php", $("#form").serialize(),
   function(data){
     alert(data);
});
