in terms of sending ajax request via javascript without relying on jquery, that's pretty broad question. should review documentation here.

a simple example

// old compatibility code, no longer needed. if (window.xmlhttprequest) { // mozilla, safari, ie7+ ...     httprequest = new xmlhttprequest(); } else if (window.activexobject) { // ie 6 , older     httprequest = new activexobject("microsoft.xmlhttp"); }  httprequest.open('post', url); httprequest.setrequestheader('content-type', 'application/x-www-form-urlencoded'); var data = /* data here */ httprequest.send('data=' + encodeuricomponent(data)); 

to retrieve in php use either $_post or file_get_contents('php://input') depending on content-type header sent in request. above example use application/x-www-form-urlencoded content-type header, post http verb, information populated in $_post['data'].
