Javascript/Jquery Post and Get?

Is it possible to have a piece of code or a function that does the following.

I would like for a javascript file to send a request to a different domain of mine with a variable. This webpage would check the variable against the database and return to the original javascript file the result of being either TRUE or FALSE

I didn't know of JSONP and used a diffrent approach 

$.ajax({
    type: "GET",
    crossDomain:true,
    url: 'http://otherdomain/check.php',
    success: function(data) { 
        // check.php response
    }
});

and in check.php

<?php
$allowable_hosts = array('http://originaldomain','http://anotherdomain');
if (in_array($_SERVER['HTTP_ORIGIN'],$allowable_hosts))
    header('Access-Control-Allow-Origin: *');
//echo "ok"; - your check code
?>

If you are sending requests between domains, you should have a look at http://api.jquery.com/jQuery.ajax/ with the dataType set to jsonp to load the response using a script tag.
