here html form:

to value of selected radio box can use $('input:radio[name="search_method"]:checked').val();

$("#faq_search_input").watermark("begin typing search"); $("#faq_search_input").keyup(function() {     updateresult();     return false; });  $('input[name="search_method"]').on('click', updateresult)  function updateresult(){     var faq_search_input = $('#faq_search_input').val();     var datastring = 'keyword='+ faq_search_input;     if(faq_search_input.length>1)     {         var search_method = $('input:radio[name="search_method"]:checked').val();          $.ajax({             type: "get",             url: "<?php echo $site_config_url; ?>/resources/ajax-search" + (search_method == 'cartridge'? '': '2') + ".php",             data: datastring,             beforesend:  function() {                 $('input#faq_search_input').addclass('loading');             },             success: function(server_response){                 $('#searchresultdata').html(server_response).show();                 $('span#faq_category_title').html(faq_search_input);                  if ($('input#faq_search_input').hasclass("loading")) {                     $("input#faq_search_input").removeclass("loading");                 }             }         });     } }
