推荐答案

（'＃drprojecttype'）。val（Dedicated）;

('#drprojecttype').val("Dedicated");

（＃drprojecttype option [ value ='Dedicated']）。attr（selected，selected）;
//

("#drprojecttype option[value='Dedicated']").attr("selected", "selected"); //

（＃drprojecttype）。val（Dedicated）;
}
else {
//

("#drprojecttype").val("Dedicated"); } else { //
