Project Description:
This project will entail creating a raw Javascript (not jQuery) function to POST data to a remote URL without updating the client, or causing a page refresh.

The code should accept keys and data to be transmitted. The current format, using jQuery post, is as follows:


var data01 = "data";
var data02 = "data";
var data03 = "data";

$.post("", {var1: data01,
var2: data02,
var3: data03},

The code must be flexible enough to work across all browsers and platforms, including mobile. If necessary, mobile browsers can use a separate function, but the preference is for an integrated function that handles each case. Because of this cross-platform requirement, jQuery (and jQuery mobile) is not a suitable implementation.

Skills required:
AJAX, Javascript
