Select2 自动设置选项

Question

我正在构建一个支持应用程序，它有一些 select 框。我为此使用 select2。我遇到的问题是，在我当前的构造中，只有当有人在项目 select2 填写项目后单击线索 select2 时，才会出现项目对应线索的 selection select2.

目标是当有人设置项目 select2 值时，程序会自动将潜在客户 select 框的 select2 设置为潜在客户对应项目的ID。

如果我在工程select2处select工程1082，需要在select2处自动设置"J. Johnson"，不用我必须先点击 selectbox.

即使有官方文档 (https://select2.org/programmatic-control/add-select-clear-items) 也能达到我设想的解决方案，但我无法提供帮助，因此我将不胜感激。

项目selection onchange函数调用

$('.select2project').on("change", function() {
    var value = $(this).val();
    searchLeadsByProjectID(value);
});

searchLeadsByProjectID 函数

        function searchLeadsByProjectID(id){
            $('.select2lead').select2({
                ajax: {
                    type: 'GET',
                    url: '/modules/support/ajaxLeadSearch2.php',
                    dataType: 'json',
                    delay: 250,
                    data: {
                        "id": id
                    },
                    processResults: function (data) {
                        return {
                            results: data,
                            more: false
                        };
                    }
                }
            });
        }

ajaxLeadSearch2.php

<?php
require_once('../../config.php');

$login = new Login();
if (!$login->checkLogin()) {
    echo lang($_SESSION['language'], "INSUFFICIENT_RIGHTS");
    exit();
}

$db = new Database();

$query = "
        SELECT
            LeadID AS lead_id,
            REPLACE(CONCAT_WS(' ', LeadInitials, LeadInsertion, LeadLastName), '  ', ' ') AS name,
            REPLACE(CONCAT_WS(' ', LeadStreet, LeadStreetNumber, LeadNumberAdjective), '  ', ' ') AS address,
            LeadZiPCode AS zipcode,
            LeadCity AS city
        FROM
            `LeadTBL`
        WHERE
            LeadID = :leadID
        ORDER BY
            LeadLastName
        ASC
    ";

$binds = array(
    ':leadID' => $_GET['id'],
);
$result = $db->select($query, $binds);
$json = array();

foreach ($result as $row){
    $json[] = array(
        'id' => $row['lead_id'],
        'text' => $row['name'] .' - '. $row['address'] .', '. $row['zipcode'] .' '. $row['city'] .' ('. $row['lead_id'] .')'
    );
}

echo json_encode($json);

追加一个新选项，welp。已解决。

        function searchLeadsByProjectID(id) {
            $.ajax({
                type: 'GET',
                url: '/modules/support/ajaxLeadSearch2.php',
                dataType: 'json',
                delay: 250,
                data: {"id": id}
            }).success(function (data) {
                var $leadSelect = $('.select2lead');
                for (var index in data) {
                    var d = data[index];
                    var newOption = new Option(d.text, d.id, true, true);
                    $leadSelect.append(newOption).trigger('change');
                }
            });
        }
