So I know a lot of the posts I’ve been writing recently have been about stuff that’s been around a while–Ext helper functions, CFScript, etc. Nonetheless, I post them because some of the answers to questions I’ve found in developing solutions have been less-than-easy to find, so perhaps repeating some of the same things again will help Google find it a bit easier for someone else someday.

On with redundancy!

Obviously, JSON-related technologies have been around for a while, and with ColdFusion 8, a lot of native JSON handling was added for the creation of some sweet AJAX-y goodness.  While I’ve dabbled with these, I’ve never really had a need for them…until now.

I recently developed a remote CFC function that required about 12 different arguments.  On the client side, I also developed a quick EXT Ajax.request() method to pass these arguments into the CFC function.

Now with Ext, it’s incredibly simple to pass arguments to server-side functions, as this example illustrates:

Ext.Ajax.request({
     url: 'com/functions.cfc',
     success: successMethod,
     failure: errorMethod,
     headers: {"Content-Type": "application/x-www-form-urlencoded; charset=UTF-8"},
     params: {method:'setupLife',argument1:arg1,argument2:arg2}
});

I like this alot, because it allows me to treat each argument as its own “thing,” rather than stringing together a bunch of “&argument1=arg1” in the query string.
