CFAJAX: Passing multiple parameters to function

[Josh Nathanson]

Just getting into CFAjax and loving it.  Got a question about passing
multiple parameters to the CF function in the DWREngine._execute call - how
do you do it?  I'm doing this:

function doSearch()
   {
    var _priceRange = DWRUtil.getValue("priceRange");
    var _searchText = DWRUtil.getValue("searchText");
    DWREngine._execute(_cfscriptLocation, null, 'getProducts', [
_priceRange, _searchText ], searchResult);
   }

Trying to send the variables _priceRange and _searchText to the cffunction
'getProducts' but it doesn't seem to work.  Is there a way to do this?  TIA

Have you tried passing it as an object?

That is how it works in JSMX. You just build it up and pass the entire
object to the server like this:

params = new Object();
params._priceRange = 'foo';
params._searchText = 'foo';

http( 'post' , 'myComponent.cfc?method=doSomthing' , myCallback , params );

Perhaps CFAJAX allows the same type of thing?

Got it working, but not passing the params as an object - had to build a
param string, then parse the string as a list in CF using ListGetAt.  I
noticed all the cfajax examples pass a single string argument so I presume
that's the only type of argument that will work.  If anyone knows different
let me know.

This is all descibed in the wiki - you just pass the multiple
arguments on the calling line:

Cool thanks, that makes things easier.  Will check the Wiki first next time.
