javascript - Dynamically set option selected -

how can set option value selected dynamically? have tried same by,

function editfromdb(optval) {     $.get("/myend", function(mydata) {                           var s = $('<select id="' + optval + '" name="selectname" ></select>');         $(mydata).each(function(iter, element){             $('<option></option>', {                 value: elem.name,                  text: elem.name             }).appendto(s);          });         $("#" + optval).val(optval);         // ... 

just add " selected : true"

    $('<option></option>', {                     value:"lol2",                      text: "yo2",                     selected : true                 }).appendto($("#test"));  

two ways use :

$(mydata).each(function(iter, element){ if (your_condition_for_selected) {             $('<option></option>', {                 value: elem.name,                  text: elem.name,                 selected : true             }).appendto(s);          }); } else {  $('<option></option>', {                 value: elem.name,                  text: elem.name             }).appendto(s);          }); } 

or can :

$(mydata).each(function(iter, element){ if (your_condition_for_selected) {             $('<option></option>', {                 value: elem.name,                  text: elem.name,                 selected : your_boolean_condition   }).appendto(s);          }); }
