Why does $.ajaxSetup not work with $.post

Question

Why does this code post the sessionID parameter

    $.post("ajax/p_getOnePosition.jsp", {
        positionNo: positionNo,
        sessionID: v_sessionID,
    }, function(response2) {

But not this code

    $.ajaxSetup({
        sessionID: v_sessionID,
    });
    
    $.post("ajax/p_getOnePosition.jsp", {
        positionNo: positionNo,
    }, function(response2) {

What is `v_sessionID` and when is it set? After `$.ajaxSetup` called? — freedomn-m, Jan 07 '21 at 17:28
It is a security token. It is set before $.ajaxSetup is called. — gordon613, Jan 07 '21 at 17:33

Use beforeSend instead as follows. Code inspired from here

$.ajaxSetup({
     beforeSend: function (jqXHR, settings) {
        settings.data += "&sessionID="+v_sessionID;
  }
});

$.post("ajax/p_getOnePosition.jsp", {
    positionNo: positionNo,
}, function(response2) {
