in reply to Using CGI::Ajax for multiple form buttons/divs simultaneously
AJAX is initiated on the client side and it has nothing directly to do with <DIVs nor with any other HTML or DOM structures. It consists of making an asynchronous HTTP request ("XHR"), which sends a payload via either GET or POST to a specified host-side URL. When the host sends its reply, a callback subroutine (in JavaScript), specified when the XHR was issued, will be invoked. This callback will be given both the HTTP error-code and the entire content of the host's response, which serves as its input data. This response will not appear anywhere on the screen unless the callback routine, in response to whatever it has received, chooses to manipulate the DOM in some visible way. You can manage XHR-requests on the client side using a piggish library like JQuery, or with a roughly 20-line JavaScript function or object which is available anywhere on the Internet.
