Saving data to the database via JQuery .ajax

I am attempting to save 2 pieces of information to the database via JQuery using the .ajax function. I want to save the postID and the userID in WordPress. I think I get the jist of most of the function but need to figure out how to send an array to the processing page so I can insert it. This is what i have written so far:

 $(document).ready(function() {
        $('#saveme').click(function() {
            $.ajax({
            type: "POST",
            url: "save_data.php",
            contentType: "application/json; charset=utf-8",
            data: "",
            dataType: "json",
            success: function (msg) {
                alert("This recipe has been saved in your profile area!");
            }

        });
    });

Can anyone shed some light one what goes into the data value to store the 2 pieces of information that I can send to the processing page?

I am using PHP and the code is in a .js file so I might need to also know to send the information over to the js file. Thanks!!

The type of Data to be sent to the server is JavaScript object containing zero or more key-value pairs or String. For your case

data: { 'postID' : $('#postID').val(), 'userID' : $(('#userID').val() },

You forgot to add data

$(document).ready(function() {
   var postID='<?php the_id(); ?>';
   var userId='<?php author_id(); ?>';
        $('#saveme').click(function() {
            $.ajax({
            type: "post",
            url: "save_data.php",
            contentType: "application/json; charset=utf-8",
            data: {postID: postID, userId: userId},
            dataType: "json",
            success: function (msg) {
                alert("This recipe has been saved in your profile area!");
            }

        });
    });

Just create a JSON object and send it: (assuming say there is an element on the page by the id of postID and userID

var jsonData = { "postID" : $("#postID").val(),
                 "userID" : $(("#userID").va;() }


 $(document).ready(function() {
        $('#saveme').click(function() {
            $.ajax({
            type: "POST",
            url: "save_data.php",
            contentType: "application/json; charset=utf-8",
            data: jsonData,
            dataType: "json",
            success: function (msg) {
                alert("This recipe has been saved in your profile area!");
            }

        });
    });

data should be a JSON object containing the data you want to save, i.e.

$(document).ready(function() {
        $('#saveme').click(function() {
            $.ajax({
            type: "POST",
            url: "save_data.php",
            contentType: "application/json; charset=utf-8",
            data: {postID: "A123456", userId: "HGSADKJ"},
            dataType: "json",
            success: function (msg) {
                alert("This recipe has been saved in your profile area!");
            }

        });
    });
