Also, the can reside within [!][/!] tags... which can also prevent them from being displayed. so:----------- [!][/!][!] [/!][function name=someFname]
[search..blah][return][founditems][blah][/founditems][/return][/search] [/function][someFname] -------------- May work for you. Regarding JSON.. I don't think Chris is planning on worrying about this anytime soon (because of other pressing priorities).. but since JSON is just a format (such as XML) any one of us could write a function lib to encode/decode for JSON.. perhaps from encoding from founditems, or an array etc?? http://www.json.org/ There are 3 very important data exchange formats that standard AJAX snippets will use.. text(string), XML, and JSON... so it would be good for us to have a JSON encode/decode util. to work with. Right now, 6.x (at least on the apache builds).. doesn't work with XML ajax snippets because you can't over-ride the content-type to a value of text/html... try it yourself: in a template have the code: [setmimeheader name=content-type&value=text/XML] then hit the page with a mime header viewer of some kind (firefox has a mimeheaders plug-in for example). Anyway, the AJAX object 'responseXML' requires the XML content-type.. so WebDNA (at least the apache 2.x builds) do not currently work with AJAX snippets that make use of the 'responseXML' component. I brought this up with Chris.. and we discovered that this will work with the up coming fastCGI app.. but Chris will have to decide if he wants to address it for the module version. I am guessing the problem resides in the open source WebDNA apache module, and I'm also guessing it is a simple fix. Anyway.. that's what I know about WebDNA and AJAX right now. My suggestion for anyone that is looking around for AJAX snippets is to look for the "responseText" object and don't use snippets that contain the 'responseXML' object for now. With 'responseText', you should be able to easily integrate with WebDNA.. however, there are sure reasons to use XML... here is some more info about all of this: http://www.developer.com/xml/article.php/3596836/Speeding-Up-AJAX-with-JSON Cheers, Donovan -- Donovan Brooke Euca Design Center [Practical-Ethical-Efficient] www.euca.us egg.bz artglass-forum.com
