$(document).on("click", "#edit", function(e){
   e.preventDefault();
   var editid = $(this).attr("value");
 $.ajax({
      url: "<?php echo base_url();?>Rayon/editdata",
      type: "POST",
      dataType: "json",
      data:{editid: editid},
      success: function(data){
      if(data.responce == "success"){
         $('#editm').modal('show');
         $("#edit_Kode_rayon").val(data.posts.kode_rayon);
         $("#edit_nama_rayon").val(data.posts.nama_rayon);
         //$("#nRegionE").val(data.posts.kode_region);<-- I TRIED LIKE THIS .. NOT WORK -->
         //$("#nRegionE").select2().select2('val',data.posts.kode_region);<-- I TRIED LIKE THIS . NOT WORK-->
         $('#nRegionE').val(data.posts.kode_region).trigger("change");<-- EVEN THIS ONE IS NOT WORK -->
      }else{
         toastr["error"](data.message);}
      }
      });
      });

and here is my Select2 script that im using it for inssert and my edit form:

$(function () {$('.kode_region').select2({
 //placeholder: "Please select region",allowClear: true,

You are fetching options list correctly in data.posts.kode_region, then update this line

$("#nRegionE").val(data.posts.kode_region);

to this

$("#nRegionE").html('<option value = "'+data.posts.kode_region+'" selected >'+data.posts.kode_region+'</option>');

and don't forget to comment this line

$('#nRegionE').val(data.posts.kode_region).trigger("change");

I am dam sure this will work for you

$("select#nRegionE option").val("hello"); //Change hello string to your record Id
$("select#nRegionE option").html(data.posts.kode_region);
