AS2 Refresher: sendAndLoad XML
January 12th, 2010 — 11:23am
The following article assumes you have a solid understanding of Flash AS2 and the Flash interface and skips all basic Flash setup instructions and explanations in effort to provide you with quick, concise information. It also assumes you are dealing with a server-side script that is set up to receive parameters and send back XML.
The AS2 refresher series aims to consolidate basic, everyday snippets for the most common tasks used by Flash developers working with legacy files. Basic explanations are included in the comments, since after all, who wants to read through a bunch of crap when you are just after the code? Enjoy.
