Preselecting value in select2

Question

Texbox is dynamically filled with a remote call using Select2 and how do I set preselected value. Here is the code

<input type="hidden" id="e6">

$("#e6").select2({
    placeholder: "Search for a movie",
    minimumInputLength: 1,
    ajax: {
        url: url,
        dataType: 'jsonp',
        data: function (term, page) {
            return {
                q: term, // search term 
                page_limit: 10, }; 
        }, 
        results: function (data, page) { 
                return {results: data};
        }
    }
});    

I tried this to preselect value 1049

$('#e6').select2('val', '1049');

but this doesn't set the value on the textbox.

Any ideas?

Answer 1

in 2019 this worked for me

    // Create a DOM Option and pre-select by default~
    var newOption = new Option(data.text, data.id, true, true);
    // Append it to the select
    $('#mySelect2').append(newOption).trigger('change');

Answer 2

In case anybody wants to know how to solve this

$("#e6").select2('data', {id: '1049', text: 'MyLabel'});
