Ugh - that's right. It is actually more simple than it looks - it makes a lot more sense when you actually get to use it ;)
Well then, this should work for you (http://jquery.bassistance.de/api-browser/#postStringMapFunction): I hacked Christopher Jordan's example because I like the loop over the form fields to build the object :) I would highly recommend using firebug with firefox either in the console or on the net tab to watch how all of this works. You can see the actual post and what is returned that way. This example returned a simple string. You can also download the wddx sdk at www.openwddx.org to get the javascript ser/deser functions. This will allow you to return complex objects such as queries, structures, arrays or combinations of those using <cfwddx action="cf2wddx"> (available in cf 4.5) in the same manner. When the wddx packet hits your processing function you would deserialize the packet into a javascript object then loop over it or what ever else you need to do to deal with the results. === Calc page: <script type="text/javascript" src="/js/jquery.js"></script> <script type="text/javascript"> function CalculateMortgage(){ var Params = {}; // select all inputs of type text $("input:text").each(function(){ Params[$(this).attr("name")] = $(this).val(); }); // "post" the form. The Param object mimics form fields $.post("/path/to/yourdatapage.cfm", Params, function(data){ // this is the processing function. // append what you get back to the element with ID = Result after clearing its contents $("#Result").empty().append(data); } ); } </script> <form name="f"> <table> <tr> <td align="right"><strong>Principal:</strong></td> <td><input type="text" name="Principal"></td> </tr> <tr> <td align="right"><strong>Interest Rate:</strong></td> <td><input type="text" name="InterestRate"></td> </tr> <tr> <td align="right"><strong>Duration:</strong></td> <td><input type="text" name="Duration"></td> </tr> <tr> <td align="right"><strong>Result:</strong></td> <td><span id="Result"></span></td> </tr> <tr> <td align="right"> </td> <td><input type="button" value=" Calculate " onClick="CalculateMortgage();return false;"></td> </tr> </table> </form> ======== Page from which you are getting the data: <cfsetting showdebugoutput="no"><cfset calc = form.Principal * form.InterestRate * form.Duration> <cfcontent reset="yes"><cfoutput>#DollarFormat(calc)#</cfoutput> Rick Faircloth wrote: > > Hi, Daemach... > > Thanks for the guidance, but unfortunately, I'm still using > CF 4.5, so CFC's are obviously not an option.
