Using jQuery Ajax Call within ApEx - How?

Question

Hi,
I was just wondering if it's possible to replace Oracle ApEx way of performing ajax calls with a jQuery Ajax call instead - just curious if I can call an On Demand process using jQuery Ajax means?
Any examples would be much appreciated as unsure how to perform the equivalent process with jQuery.
Thanks.
Tony.

I guess I found the solution for region pull for IR report
using the syntax
gReport = new apex.worksheet.ws('');
in the js script below.
When I pull the IR region from page8 into page1, I found that the IR toolbar's html/Js scripts are missing in Page1
and thats why the IR toolbar functions were not working, issuing "gReport is null or not an object" error.
But when I added the
gReport = new apex.worksheet.ws('');
syntax in the JS script below, the toolbar functions work using the p_arg_value.
<script>
function display_report(p1) {
$s('P1_SELECTED_NODE',p1);
$.ajax({
type: "POST",
url: "wwv_flow.show",
data: {
p_flow_id : $v('pFlowId'),
p_instance : $v('pInstance'),
p_flow_step_id : "4",
p_request : "SUBMIT",
p_arg_name : 'P4_SELECTED_NODE',
p_arg_value : $v('P1_SELECTED_NODE')
dataType: "html",
success: function(data){
var startTag = '<apex4ajax>';
var endTag = '</apex4ajax>';
var start = data.indexOf(startTag);
if (start > 0) {
data = data.substring(start+startTag.length);
var end = data.indexOf(endTag);
data = data.substring(0,end);
$("#EMP_REPORT").html(data);
//Workaround to make the report "pagination" and "order by" work
$x_Value('pFlowStepId', "4");
gReport = new apex.worksheet.ws('');
//gValid = new apex.validation.v();
//gReport.navigate.paginate('pgR_min_row=51max_rows=50rows_fetched=50');
//gReport.controls.reset();
</script>
