If your server accepts JSON, you can create a JSON object with jQuery (use jQuery select statements to include the necessary input tags), then send it to the server as an object - more information here: http://encosia.com/2009/04/07/using-complex-types-to-make-calling-services-less-complex/.
Basically, do something like this:
var formInputs = { };
$('input[type=text]').each(function() {
formInputs[this.id] = this.value;
});
