Why not just call events in Mach-ii from your Ajax calls?
JS code (using prototype.js):
function getStreets:()
{
var url = ["index.cfm?"
, "event=getAddresses"
, "postcode=" + postcode
, "suburb=" + suburb
, "state=" + state
, "item=street"
].join("&");
var options = { method: "get"
, onCreate: function()
{
//do some stuff
}.bind(this)
, onComplete: function(request)
{
// do some stuff with the result
}.bind(this)
};
new Ajax.Request(url, options);
}
Mach-ii.xml
<event-handler event="getAddresses" access="public">
<filter name="securityFilter" />
<notify listener="AddressController" method="getAddresses"
resultkey="request.output" />
<view-page name="ui.getAddresses" contentkey="request.output" />
<view-page name="stringOutput" />
</event-handler>
Call the controller, get your data and then in this example ui.getAddresses
takes the query returned by the controller into a select box (but it could
anything: XML/JSON) and stringOutput actually returns the content back to the
browser.
Hope this helps.
Cheers
