I'm working with the jQuery validation plugin, and it has a feature where you can define a "remote" validation rule. This allows you to specify a url to call via ajax, and also allows you to pass arguments with the call. The limitation of the way this feature is implemented is that it expects a single word as a response, either "true" or "false". I was able to wire things up between this plugin and my MG app using the remoting service, but the remoting service is returning json data, which won't work with the plugin. There is no opportunity to intercept the data and massage it before the plugin attempts to interpret the response. I don't really care for that fact, and perhaps the best solution would be to fork the plugin and patch it so that it can interpret json data, but I wasn't feeling up to that today. ;-)
So instead I wanted to get MG to return a simple string to me. I suppose one route is to go "old school" and create an MG event with a view that only returns the single string, and maybe that is the best route. Maybe the RemotingService is really only meant to be used in situations in which you do need to receive complex data from an MG app? Maybe. But I figured that I'd try to work with the existing RemoteService infrastructure and see if I could get it to do what I wanted. It was actually fairly simple to do, but it did require a bit of refactoring in the AbstractRemotingService. The problem with the current implementation of the AbstractRemotingService is that the creation of the returned data is embedded in the executeEvent method. I refactored it to look like this: http://cfm.pastebin.com/z495z61q Then I was able to create my local RemotingService that looks like this: http://cfm.pastebin.com/By5WwSMx To get it to return plain data I simply add a returnFormat=plain argument to my request. I freely admit that it's not the most beautiful piece of code ever written, and it's value may be questionable, but I think adding the flexibility into the AstractRemotingService to allow for a developer to override the format of the data that is returned might be a nice feature. I also realize that another option would be to bypass MG entirely and simply call a cfc directly, but I wanted to see what would be done with what MG has to offer. Does anyone have any suggestions for other ways to achieve my goal, or any comments on the changes that I made to the AbstractRemotingService?
