Thanks dean, that's great -----Original Message----- From: Dean Lawrence [mailto:dean...@gmail.com] Sent: 14 March 2011 13:21 To: cf-talk Subject: Re: RE: Database Lookup - Possible with CF?
Ian, again you are mixing things up.CFJSON is not what calls the webservice. CFJSON is used to encode or decode native ColdFusion objects to and from JSON format. So if you if have a query result, you would pass that query object to CFJSON and it will encode it into JSON format. Vice-versa, you can pass it a JSON string and it can covert it back to a native ColdFusion object. So with that said, JQuery would make an AJAX call to your ColdFusion page, be it a .cfm or .cfc page (doesn't really matter as JQuery doesn't care). On that ColdFusion page you would invoke the webservice that you are getting your data from and make whatever calls that the webservice requires. If what you get back from the webservice is not in a JSON format, you would then pass the results to CFJSON to convert it to JSON. It is this converted data that you would then return to the original AJAX call and now use JQuery to populate your form with that data. I think your hang-up is on this whole ColdFusion 7 mentality. The use of JQuery to make an AJAX call and populate the form is not ColdFusion 7 specific, as it is a client-side task, it really has nothing to do with ColdFusion 7. The only ColdFusion 7 functionality that you really need to be concerned about is making the call to your .Net webservice. Here is Adobe's LiveDoc page that tells you how to do that. http://livedocs.adobe.com/coldfusion/7/htmldocs/wwhelp/wwhimpl/common/ht ml/wwhelp.htm?context=ColdFusion_Documentation&file=part_dev.htm As for ColdFusion 7 and JSON, JSON is really only text. Again, you don't need anything special to work with it. Projects like CFJSON simply make it easier to work with it. But if you look at the source code for CFJSON, it is just using plain old ColdFusion to process the data. The same holds true for newer version of ColdFusion. The built-in tags are just a way to make it easier to work with JSON, but are not required. I'm running ColdFusion 9.01 and don't use any of the built-in tags to do my AJAX calls as I like to have full control over the process. That's just me though. Anyway, here is a link to the JSON homepage so that you can get a better understanding about what it is. http://www.json.org/ Dean On Mon, Mar 14, 2011 at 7:24 AM, Ian Vaughan <i.vaug...@neath-porttalbot.gov.uk> wrote: > > Thanks found this link > http://www.monochrome.co.uk/blog/2008/02/01/using-jquery-and-coldfusion- > 7-with-a-little-json-glue which seems ok - the problem I am having in > understanding is how would I use CFJSON to use the .asmx webservice data > that I would consume/call with the Coldfusion 7 cfinvoke tag? > -- ------------------------------------------------------------------------ --- Dean M.
