I believe what you're trying to do is what serializeArray() function
in jQuery already does:
http://docs.jquery.com/Ajax/serializeArray
$("button.save").click(function(){
var action = $(this).parent("form").attr("action");
var postThis = $(this).parent("form").serializeArray();
$.post(action, postThis, function(data){
alert("done");
});
return false;
});
