 How to Call Modal Dialog in Apex Using Java script and Pass the Parameters

Create a Dynamic Action and Use the Code on Double Click Event

var x = apex.item('P492_COSTNO').getValue();
var url = "f?p=#APP_ID#:493:#SESSION#::NO:RP,493:P493_COSTNO:#P492_COSTNO#";
url = url.replace("#APP_ID#", $v("pFlowId"));
url = url.replace("#SESSION#", $v("pInstance"));
url = url.replace("#P492_COSTNO#", x);
apex.server.process("PREPARE_URL", {
x01: url
  }, {
  success: function(pData) {
   if (pData.success === true) {
     apex.navigation.redirect(pData.url);
   } else {
     console.log("FALSE");
   }
 },
error: function(request, status, error) {
console.log("status---" + status + " error----" + error);
  }
});

declare

result varchar2(23333);

begin

result:=apex_util.prepare_url(apex_application.g_x01);

apex_json.open_object;

apex_json.write('success', true);

apex_json.write('url', result);

apex_json.close_object;

exception

when others then

apex_json.open_object;

apex_json.write('success', false);

apex_json.write('message', sqlerrm);

apex_json.close_object;

end;
