How to set selected value of jquery select2?

Question

This belong to codes prior to select2 version 4

I have a simple code of select2 that get data from ajax

Answer 1

To dynamically set the "selected" value of a Select2 component:

$('#inputID').select2('data', {id: 100, a_key: 'Lorem Ipsum'});

Where the second parameter is an object with expected values.

UPDATE:

This does work, just wanted to note that in the new select2, "a_key" is "text" in a standard select2 object. so: {id: 100, text: 'Lorem Ipsum'}

Example:

$('#all_contacts').select2('data', {id: '123', text: 'res_data.primary_email'});
