RE: Code from cfhtmlhead showing up in jQuery AJAX JSON data
Duh... Steve, what you and Russ have pointed out makes perfect sense.
My initial thought was to use onRequestStart, but for some reason
decided to use onApplicationStart, which wouldn't work for every page.
I guess I was thinking of just creating the variables once for
global use, rather than focusing on the fact that I needed to create
them for every page.
Thanks for the tip! (...and the code, Steve! :o)
And yes, it's CF9...

You wouldn't put it in onApplicationStart, but onRequest (cf9+).
onRequest is only triggered on cfm requests, whereas a cfc would trigger
onCFCRequest. (I am assuming your Ajax requests are going to a CFC)
Set up your js vars in onApplicationStart
application.siteDetail = {"js_sitename"=application.sitename,
"js_website"=application.website,
"js_site_manager_dsn"=application.site_manager_dsn,
"js_client_dsn"=application.client_dsn }
Then, in your onRequest (though some header include custom tag, included
at the page level, would be better and give greater flexibility)
var siteDetail =
#SerializeJSON(application.siteDetail)#;
Then, in your JS, access the vars from the JS obj
... // some JQuery Ajax call data object
data: $.extend(true,{},siteDetail,{someArg:1,someArg2:'myArg'})
There's probably many ways to handle all of this, but putting the output
in your onApplication or onSession methods is not the way to go.

Re: Code from cfhtmlhead showing up in jQuery AJAX JSON data
You wouldn't put it in onApplicationStart, but onRequest (cf9+).
onRequest is only triggered on cfm requests, whereas a cfc would trigger
onCFCRequest. (I am assuming your Ajax requests are going to a CFC)
Set up your js vars in onApplicationStart
application.siteDetail = {"js_sitename"=application.sitename,
"js_website"=application.website,
"js_site_manager_dsn"=application.site_manager_dsn,
"js_client_dsn"=application.client_dsn }
Then, in your onRequest (though some header include custom tag, included
at the page level, would be better and give greater flexibility)
var siteDetail =
#SerializeJSON(application.siteDetail)#;
Then, in your JS, access the vars from the JS obj
... // some JQuery Ajax call data object
data: $.extend(true,{},siteDetail,{someArg:1,someArg2:'myArg'})
There's probably many ways to handle all of this, but putting the output
in your onApplication or onSession methods is not the way to go.

Re: Code from cfhtmlhead showing up in jQuery AJAX JSON data
well using your current method the vars will of course will only be created and output once when application starts, so wont exist on any subsequent requests, which I do not think is what you want if they are JS variables you want them output on every page request in order for them to be available to JS, so you would need to do it onrequestStart or just by putting them in the actual html head. Technically if there is no HEAD section then CF should not be trying to insert the content, so in your CFC's you need to make sure you have output disabled so that unnecessary content doesn't get added. You may also need to make use of is some places as well.

RE: Code from cfhtmlhead showing up in jQuery AJAX JSON data
Only onApplicationStart currently. I thought about using onRequestStart, but it needs to always be on the page, anyway, so I thought I'd do it once in the onApplicationStart routine. Is that a problem? Oh, wait... do you mean every "page request" or every AJAX "request" for data? -Original Message- From: Russ Michaels [mailto:r...@michaels.me.uk] Sent: Saturday, September 24, 2011 8:00 AM To: cf-talk Subject: Re: Code from cfhtmlhead showing up in jQuery AJAX JSON data it is only happening onApplicationstart or is it being inserted into every request ?
