javascript - 选择 2 问题，更改事件未在第二次选择时触发

Question

我遇到了选择 2 的问题，其中第二个选择 2 从 AJAX 中拉出，它返回要替换的 HTML。

主要问题似乎是第二个 select 2 'select' 没有添加选定的属性，因为某些上帝遗弃的原因...... console.log 没有启动。

function select2_format_flag(state) {
    var originalOption = state.element;
    if (!$(originalOption).data('iso')) return state.text;
    return "<img class='flag' src='<?=$adtrafik_config['uri_assets']?>img/flag/" + $(originalOption).data('iso') + ".gif' /> " + state.text;
}

function select2_format_engine(state) {
    var originalOption = state.element;
    if (!$(originalOption).data('engine')) return state.text;
    return "<img class='engine' src='<?=$adtrafik_config['uri_assets']?>img/img/engine/" + $(originalOption).data('engine') + ".png' /> " + state.text;
}


jQuery(document).ready(function () {
    //API Path
    var adtrafik_api = '<?=$adtrafik_config['
    uri_post '].'
    seo / report - regional / api / '?>';
    //Select2
    $('#go').attr('disabled', 'disabled');
    $('#d_to').attr('disabled', 'disabled');
    $('#d_from').attr('disabled', 'disabled');
    //Init. Select2
    $('#d_engine').select2({
        placeholder: "Select Engine...",
        allowClear: true,
        width: 'resolve',
        formatResult: select2_format_engine,
        formatSelection: select2_format_engine
    });
    $("#d_market").select2({
        width: 'resolve',
        formatResult: select2_format_flag,
        formatSelection: select2_format_flag
    });
    $('#go').click(function (event) {
        event.preventDefault();
        var d_from = $('#d_from').val();
        var d_to = $('#d_to').val();
        var data_key_engine = $("#d_engine option:selected").attr('data-engine').toLowerCase();
        var engineid = data_key_engine;
        //var engineid = data_key_market + '-' + data_key_engine;
        <? php
        if (isset($uri_page[2])) { ?>
                window.location.href = '<?php echo $adtrafik_config['
            uri_post '].'
            seo / report - regional / overview / '; ?>' + engineid + '/' + d_from + '/' + d_to + '/'; <? php
        } else { ?>
                window.location.href = '<?php echo $adtrafik_config['
            uri_post '].'
            seo / report - regional / '.$uri_page[2].' / '; ?>' + engineid + '/' + d_from + '/' + d_to + '/'; <? php
        } ?>
    });
    //Add Formatter and AJAX to Market
    $('#d_market').change(function () {
        var id = $('#d_market').val();
        var dataString = 'type=nav&call=d_engine&d_market=' + id;
        var data_key_market = $("#d_market option:selected").attr('data-iso').toLowerCase();
        $.ajax({
            type: 'GET',
            url: adtrafik_api,
            data: dataString,
            cache: false,
            success: function (html) {
                $('#d_engine').select2('enable');
                $('#d_engine').html(html);
            }
        });
    });
    $('#d_market').change(function () {
        console.log('i changed');
    });
    $('#d_engine').change(function () {
        console.log('i changed too....');
    });
    //END this crap!
});
