Answer 1

Use jQuery AJAX , This is good source

$.ajax({
  type: "POST",
  url: "MessagePopup.asmx/SendMessage",
  data: "{subject:'" + subject + "',message:'" + message + ",messageId:'" + messageId + "',pupilId:'" + pupilId +"'}",
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(msg) {
    // Do something interesting here.
  }
});

If you want just using JavaSctipt without using jQuery fallow this links
