javascript-perl interaction

PriNet has asked for the wisdom of the Perl Monks concerning the following question:

is there a way for javascript on the client side to "signal" or cgi something back to the server that can be polled so that i know the javascript event was envoked...? i'm trying to find a way for a javascript on the client to change a variable on the server side in perl...

The concept you're after is AJAX (Asynchronous Javascript and XML). The javascript should use the XMLHttpRequest object provided by the browser to make HTTP requests to the server. Although the AJAX acronym specifies sending XML messages, you can send whatever you like. Various javascript libraries exist to help you do AJAX (and other javascript tasks) more easily (and with browser bugs smoothed over). I'd recommend jQuery, or Dojo. -David	[reply]

Maybe hidden input field or cookie? Of course if you want interactive when use erroneousBollock suggestion.	[reply]

In addition you may want to take a look at HTML-Prototype-1.48, which contains Prototype and script.aculo.us libraries.	[reply]
