JQuery select2 set default value from an option in list?

Question

I want to be able to set the default/selected value of a select element using the JQuery Select2 plugin.

Answer 1

The above solutions did not work for me, but this code from Select2's own website did:

$('select').val('US'); // Select the option with a value of 'US'
$('select').trigger('change'); // Notify any JS components that the value changed

Hope this helps for anyone who is struggling, like I was.
