how to change select2 value programmatically

Question

I have a select2 box in bootstrap modal, I want to change the value of the select2 box but it didn't work.

I tried every single solution in previous posts and results but none of them got it work.

I use select2 4.0.2, I tested:

$('#select_id').val('val').trigger('change.select2');

$('#select_id').val('val').trigger('change');

$('#select_id').val('val').change()

It works one or two times then it stops working (randomly)

---

It works fine only when I change the select2 back to 3.x.x

Solution 1

$('#select_id').val('val').trigger('change');

is the right way, see here

Solution 2

$('#select_id').select2('val', selectedValue);

Solution 3

For Select2 with Ajax call, I struggled with lot of options, but none worked. Then i came to following solution, which works like charm $("#select_id").html($("").val('val').text('text')).trigger("change");
