如何获取已在Select2中选择的值

Question

I have a select2 box made with an select element , i am using DWR to fetch values from backend. I want to set these values to select2 element so that it appears already selected. I have tried adding selected attribute using Jquery dynamically but it doesn't work. But when i hardcode an option element with selected attribute, its working.

Any help will be greatly appreciated.

You try:

if set single value:

  $('select').val('1').trigger('change');

if set multiple values:

var selectedValues =[];
selectedValues[0] = "a";
selectedValues[1] = "c";

 $('select').select2('val', selectedValues);

if get value:

$('select').val();
$('#selectid').val();  //By id
$('[name=selectname]').val();  //By attr

or

$('select').select2("val")
