select2触发更改调试

Question

I am trying to insert dynamic values into select2.full.js version 4.0.1 but it doesn't work.

I did

var dest = '36,32'
$('#edit-dest').val(dest.toString().split(',')).trigger('change.select2'); 

But the trigger doesn't work - or rather does nothing to my select2 with no console message or anything. How can I debug this?

Html :

<select class="form-control" name="edit-dest[]" id="edit-dest" placeholder="search..." required>
</select>

Select2 init :

$("#edit-dest").select2({
  minimumInputLength: 2,
  multiple: true,
  language: "fr",
  width: '100%'
});

如果您将select2初始化分为不同的变量，那么这应该起作用：

$( '#edit-dest' ).val( dest.split( ',' ) ).select2( your_select2_init ).trigger( 'change' );
