Thanks to Sven Hasselbach who inadvertently gave me the information I needed to intercept the ajax call in dojo.
Using
// --- hijack dojo XHR calls
dojo._xhr = dojo.xhr;
var loadOld;
function hijacked( response, ioArgs ){
alert( response ); // change code here to do whatever you want. //
loadOld( response, ioArgs ); // call the original function
}
dojo.xhr = function( mode, args, bool ){
loadOld = args["load"];
args["load"] = hijacked;
dojo._xhr( mode, args, bool );
}
I was able to intercept the ajax call being made to the server. As I previously discussed in the original article I knew that the response was blank but was unable to get a handle on it – now I have.
There is also a NotesIn9 video supporting this article
Check out the demonstration (Thanks to David Leedy for hosting)

Here is a XSnippet which listend to TypeAhead-Xhr-Calls only:

… and thanks for sharing!
I have posted this XSnippet above just to give you the information about how you can identify if an ajax call is made for a type ahead search (because then there is a special “$$ajaxmode” used). Because if you catch all xhr Calls you will receive the partialRefreshs too.
Sven – thanks very much mate! I have to do a combination with your other code so that I can get the response – working on it and will update the demo once complete. Collaboration works!!
thank you 🙂
I have updates my code and updated the demo – thanks again Sven !!
