I am attempting to retrieve and set the selected value of a select element (drop down list) with jQuery.

for retrievel i have tried $("#myId").find(':selected').val(), as well as $("#myId").val() but both return undefined.

Any insight into this problem would be much appreciated.

to get/set the actual selectedIndex property of the select element use:

$("#select-id").prop("selectedIndex");

$("#select-id").prop("selectedIndex",1);
