//Step01:JS code will help you to send the request on HTTP Handler.

var var01 = document.getElementById(elementID1);var var02 = document.getElementById(elementID2);

var var03 = document.getElementById( elementID3);

var dataString = ' var01=' + var01 + '&var02=' + var02 + '&var03=' + var03;

$.ajax({

                type: "POST",

                url: "HandlerName.ashx",

                data: dataString

            })

            .done(function (msg) { alert("Done: " + msg);})
