Know how of Cross Domain Request in Jquery

Can anyone please explain how jquery handles cross domain requests? I understand the theory that it does via script using src attribute as url. But i was trying to test the same thing in plain javascript . I need to know the sequence of activities to be done for a post request. at what stage the data is sent and script element is constructed ? I am tired of asking the same at different forums where i got to see links explaining CORS. i need a to-do solution here. Thanks

PS: sorry if i am asking too much :)

The ajax request URL is set as the .src attribute on a dynamically generated script tag and a parameter is added to the URL &callback=someFunc where someFunc is a local javascript function. When the server receives the URL, it's job is to parse the generate javascript that contains the returned data and then calls the passed in function name with the data as an argument. This is usually referred to as JSONP.
