using jquery, burlesque form serialization name churned options comparison $.ajax call?

below $.ajax call, i put selects (multiple) comparison values information section?

$.ajax({
    type: "post",
    url: "http://myserver" ,
    datatype: "text",
    data: {
        'service' : 'myservice',
        'program' : 'myprogram',
        'start' : start,
        'end' : finish ,
        },
    success: function(request) {
      result.innerhtml = ask ;
    }   // finish success
  }); // finish ajax method

$('#userid option').each(function(i) {
 (this.selected == true) {

but i fit data: section?
