How can I set the value and label of a Select2 field when another field changes?

How can I set the value and label of a Select2 field when another field changes?

Hi,

I have an application which has to allow for a user to search for an occupation, with or without an occupation_group filter.

Using a Select2 field to select a filter for the search works fine.

However, if the user decided not to use a filter, the occupation_group field needs to be set to the appropriate group for the chosen occupation.

Here is my code:

// Set the value of the title and description fields when the template changes
editor.dependent( 'occupation_id', function ( val ) {
  $.each(select_options, function( key,result ) {
    if(result.id == val) {
     editor.val('title',result.text);               // Works!
     editor.val('description',result.description);  // Works!
     //** Doesn't work**: editor.val('occupation_group_id',{value:result.occupation_group_id, label:result.occupation_group} );
     // **Doesn't work:** $('#DTE_Field_occupation_group_id').select2('data', {id: result.occupation_group_id, text: result.occupation_group});
     $('#DTE_Field_occupation').select2('close');   // Works!
     filter = '';
    }
  });
});

I have checked that the result contains the required information. "title" is a text field, and "description" is a textarea, and they are set to the correct values. "occupation_group_id" is a Select2 field.

I would really appreciate any pointers.

    I forgot to mention that there are no error or other messages in the console.

    Rather than:

    {value:result.occupation_group_id, label:result.occupation_group}
    

    just pass in result.occupation_group_id (assuming that value is already in the list of options for the Select2 field).

    Hi Alan,

    Thanks! Unfortunately, the value is not necessarily there, because if the user bypasses the occupation group field and goes directly to the occupation field, the occupation_group_id select doesn't have any options at all - they would normally be filled by an ajax request after a search.

    I did try with just result.occupation_group_id and it didn't work either - no doubt because the option wasn't available in the select.

    If there is no other way, I can pre-populate the occupation_group_id options as there aren't a massive number of them. That should enable your suggestion to work, right?
