ajaxCFC documentation added

Tony,

Can you please more details? Did you run it from my server, or did you download it and ran it elsewhere? I just tested http://www.robgonda.com/blog/projects/ajaxcfc/exam... in 5 different browsers and they all worked.

Please provide details so I can either help debugging it or fix it to extend cross-browser support.

Thanks

-Rob

After some debugging, something jumped out at me. Going through the routines I see some null values (usually never good).

batch.path = "echoTest.cfc"
statsInfo = "null.echo"
query=""method=init&callCount=1&c0-scriptName=null&c0-methodName=echo&c0-id=9922_1134429393155&c0-param0..."

Steve,

Thank you for all the provided information. I will try to download the zip that's up there and get back to you shortly.

-Rob

Thanks to Tony I found what was bugging out on some web servers. I was calling the cfc’s with the following format: /path/file.cfc/exec/methodname?somevars

It worked fine with Apache and IIS6, but seems like some Web Servers, or Firewalls perhaps were blocking this syntax… I am still unsure which one was the exact cause, but Tony pointed me to his files and I was able to make it work by rewriting the url in a different format.

I just updated the zip file; make sure you clear your cache, especially Firefox users, as it caches all Javascripts and won’t pick up the changes unless you do so.

Cheers

-Rob

Tony,

Did you clear your cache? I just tested your link and it came back fine... both btw, the echo and the complexObjects... please make sure you clear your cache and try again.

-Rob

Interesting, I'll make a special note about hitting it with Homesite.
Thanks,
Rob

Steve,

That makes sense now … Tony said that his code worked remotely, from the office, and from my pc too, but he couldn’t run it locally; probably again because of the same thing… debugging turned on for localhost.

I’ll add some adjustments to turn off debugging automatically for the ajax calls.

-Rob

Tony,

I'm heading out, so I'll add this to the documentation later;

anyways, you can do the following when receiving recordsets in the call back function:

alert( r.getRowCount() ); // will get your the recordcount

and

document.write( r.dump() ); // dump() will return a full data dump.

it comes as a structure of arrays, not an array of structures... that's why you can't get r.length.

you need to use r.col[i] instead of r[i].col

hope it helps.

Russ,

Yes you can. There's a setter that's part of ajax.cfc that aborts the request after processing the response. Simple call the setAbortAfterRequest(true) function in your components (the one that extends ajax). Add that line outside all functions, so it gets executed onLoad.

Hello, sorry about the english i'm an spanish guy... I have been recently working with ajaxcfc, because i just want to make a simple remote access to a database without refreshing the browser... i just can't make it... i will paste here my code hoping somebody help me... thanks...


this is what i have written in the client side:

<script type='text/javascript'>_ajaxConfig = {'_cfscriptLocation':'Components/my_com.cfc', '_jsscriptFolder':'ajaxCFC/core/js'};</script>

<script type='text/javascript' src='./ajaxCFC/core/js/ajax.js'></script>



<script type="text/javascript">
function imprimir_modelos(result)
{
    alert(result);
document.getElementById('td_modelos').innerHTML=result;
}

function modelos_de(id)
{
alert(id);
DWREngine._execute(_ajaxConfig._cfscriptLocation,null,'f_modelos',imprimir_modelos);
}
</script>


and here is my component on the server side:

<cfcomponent extends="ajax" >
   
   <cffunction name="f_modelos" access="public" returntype="string">
      
      
      <cfargument name="id_categoria" type="numeric" required="no">
   
      <cfset myResult="">
      
      <cfif IsDefined("arguments.id_categoria") AND arguments.id_categoria NEQ "">
         
         <cfquery name="q_modelos" datasource="#request.dsn#" username="#request.dsnUsername#" password="#request.dsnPassword#">
            select * from tbl_products where product_Category_ID = #arguments.id_categoria#
         </cfquery>
         
         <cfoutput query="q_modelos">
         
            <cfset myResult = myResult & '<input name="model_#product_ID#" type="button" value="#product_Name#">'>
         
         </cfoutput>
         
      </cfif>
      
      
      
      <cfreturn myResult >
   
   
   </cffunction>


</cfcomponent>

sometimes it show me an error like an "alert" saying "object error", and sometimes "invalid reply from server"

thanks

hi, we've been using ajaxCFC which seems to work fine on our Production Server, and our Test Server, but does not seem to work in our local environments on our laptops. One uses ColdFusions web server, the other uses IIS, but neither work. We get the [Object Error] message. I've tried tracing and debugging in Firefox/Firebug (very useful, by the way). I'm able to set breakpoints, step through it line by line, see values for all variables, etc. In the engine.js DWREngine._sendData function, I get to the following line:
batch.req.open("POST", batch.path, batch.async);

The same files and same exact code work on 2 different servers, with all kinds of ajax usage scenarios (querying data, saving data, auto-suggest controls, etc.) -- but none of them work on our laptops -- indicating some sort of configuration issue.

We did see some of the other posts here, and have since turned off Debugging, clearing the cache, but nothing seems to help. We just keep getting the [Object Error] message.

Anything anyone can recommend? or any other testing paths to go down?
Any help would be greatly appreciated.

Scott

@Scott, I highly recommend you install some sort of http traffic analyzer, such as Firebug, Fiddler, Service Capture, or Charles. They will show you the exact request/response message and indicate that the server's responding. If it's only locally, it might be related to CF Debugging.
