POST form to a page

POST form to a page

I am new to jQuery, I would like to be able to find an example in ASP where jQuery uses Ajax HTML request to POST a form to a page.
 
I have looked at the following page:

 

http://api.jquery.com/jQuery.post/

 

I have been unable to find a simple example in ASP when this is implemented.

 

Can anyone provide me with a simple example?

 

Thanks.
