Hi, Daemach... Thanks for the guidance, but unfortunately, I'm still using CF 4.5, so CFC's are obviously not an option. I plan to upgrade this summer to CF 8 and catch up with everyone.
I was looking over your code, too... that complicated stuff! (For someone just starting out, anyway...) After looking over the code, I can begin to see how it's being done... just wish I could use AjaxCFC! Thanks for your time and help!

Hi Rick - This is one of those things I would use ajaxCFC for since it handles serialization automatically. The idea here is that you need to serialize the values of your form fields, send them to the server, deserialize, calculate and put the results into some kind of structure which gets serialized again and returned to the browser for processing which starts with deserializing. Dealing with the serialization/deserialization transparently is what makes ajaxCFC so great. First, download ajaxcfc here: http://www.robgonda.com/blog/projects/ajaxcfc/download.cfm in the zip file drill down to ajaxCFC/branches/jquery/core/. Put the .cfc's in some accessible folder on your web server, then copy everything inside the /js folder to your javascript repository - I create a subfolder to keep it separate: /js/ajaxCFC. That's it for the install. This sample code should get you started. I stuck the ajax call directly into the click event on the button, but you could put all of that in a separate function and then call the function from the click event handler if you want. =========================== your html/cfm page with the calculator: <script type="text/javascript" src="/js/jquery.js"></script> <script type="text/javascript" src="/js/ajaxCFC/jquery.AjaxCFC.js"></script> <script type="text/javascript"> // additional files $.AjaxCFC({require:'json'}); // more additional files // $.AjaxCFC({require:'json,wddx,dDumper,log4j,DWRSyntax,blockUI'}); // optional global settings // using these setters also automatically include dependencies //$.AjaxCFCHelper.setAjaxLoadImage("#snort","/images/ajax_circleball.gif"); $.AjaxCFCHelper.setDebug(false); $.AjaxCFCHelper.setBlockUI(false); $.AjaxCFCHelper.setUseDefaultErrorHandler(false); $.AjaxCFCHelper.setSerialization('json'); // json, wddx $(document).ready( function() { // Add click event to button $('#ajaxit').click(function() { //create an object to pass to the cfc. can also be an array, simple value, whatever you want. Objects turn into cf structures. var obj = {firstVal:$('#firstVal').val(), secondVal:$('#secondVal').val(), thirdVal:$('#thirdVal').val(), randomstring:"why not"} //do ajax call $.AjaxCFC({ url: "/pathto/your.cfc", method: "calculate", data: obj, // can be an anonymous function, or the name of the function that will handle the return results. success: showResults }); }); }); function showResults(data){ // data will be whatever the cfc passed back in js format - structure in this case to make it easy. $('#result').val(data.results); } </script> firstVal: <input id="firstVal" name="firstVal" type="text"><br> secondVal: <input id="secondVal" name="secondVal" type="text"><br> thirdVal: <input id="thirdVal" name="thirdVal" type="text"> <input id="ajaxit" type="submit" name="ajaxit" value="AjaxIt"> <hr> result: <input id="result" name="result" type="text"> ================ Your cfc file should go in the same folder as ajax.cfc: <cfcomponent extends="ajax"> <!--- <cfscript> setDebugMode('request'); </cfscript>---> <cffunction name="calculate" output="no" access="private"> <cfscript> obj = arguments; data = structNew(); temp = obj.firstVal + obj.secondVal + obj.thirdVal; StructInsert(data, "results", temp); </cfscript> <cfreturn data> </cffunction> </cfcomponent> Rick Faircloth wrote: > > Hi, all. > > I've just started using jQuery recently and now > I'm trying to understand how to use it with AJAX > and I just don't know enough about how it works > to get started on a fairly simple app. The sample app I've > been tinkering with sends a URL variable for a User_ID > using AJAX to a CF page, which runs a query and > returns the info to the calling page and appends > it to the body.
