问题
I have 2 flex apps on the same page. I want them to be able to call each other's public functions. I am thinking of using either externalInterface calls or FaBridge to do so. Is there a better way to do it?
回答1:
The best way to go is to use LocalConnection. It allows you to call methods from a separate SWF without having to go through Javascript or a server.
Tip: if you're going to be sending arguments that are greater than about 20KB in size, you will want to split them up in two or more calls. In my experience LocalConnection calls have a limit of around that size for data.
