AMD / select2行为障碍？

Question

我试图在这里修改select2 2/ AMD示例：https://stackoverflow.com/a/31600521/567736，我不确定我遇到的问题是否与select2有关，还是我误解了AMD。我的代码：

​

$.fn.select2.amd.define("InlineSearchSelectionCustomAdapter", [
    "select2/utils",
    "select2/selection/multiple",
    "select2/dropdown/search",
],
    function (Utils, MultipleSelection, Search) {
        let adapter = Utils.Decorate(
            MultipleSelection,
            Search
        );

        return adapter;
    }
);

$.fn.select2.amd.require([
    'select2/selection/multiple',
    'select2/selection/search',
    'select2/utils',
    'InlineSearchSelectionCustomAdapter'
], function (MultipleSelection, Search, Utils, InlineSearchSelectionCustomAdapter) {

    let SelectionAdapter = Utils.Decorate(
        MultipleSelection,
        Search
    );

    $('.inline-search-original').select2({
        selectionAdapter: SelectionAdapter
    });

    $('.inline-search-amd').select2({
        selectionAdapter: InlineSearchSelectionCustomAdapter
    });
});

.select2-selection__choice__remove {
    display: none !important;
}

.select2-container--focus .select2-autocomplete .select2-selection__choice {
    display: none;
}

<script src="//cdnjs.cloudflare.com/ajax/libs/select2/4.0.0/js/select2.full.js"></script>

<p>With an inline search box, original</p>
<select style="width: 200px" class="inline-search-original" multiple>
    <option value="AL">Alabama</option>
    <option value="AK">Alaska</option>
    <option value="AZ">Arizona</option>
</select>

<p>With an inline search box, using amd</p>
<select style="width: 200px" class="inline-search-amd" multiple>
    <option value="AL">Alabama</option>
    <option value="AK">Alaska</option>
    <option value="AZ">Arizona</option>
</select>

​

如您所见，我正在尝试将SelectionAdapter重构为一个单独的模块InlineSearchSelectionCustomAdapter。但是，我的新<select>的外观和行为与最初的堆栈溢出帖子不同。

为什么行为不同，如何纠正我的错误？

导入select2/selection/search而不是select2/dropdown/search

​

$.fn.select2.amd.define("InlineSearchSelectionCustomAdapter", [
    "select2/utils",
    "select2/selection/multiple",
    "select2/selection/search",
],
    function (Utils, MultipleSelection, Search) {
        let adapter = Utils.Decorate(
            MultipleSelection,
            Search
        );

        return adapter;
    }
);

$.fn.select2.amd.require([
    'select2/selection/multiple',
    'select2/selection/search',
    'select2/utils',
    'InlineSearchSelectionCustomAdapter'
], function (MultipleSelection, Search, Utils, InlineSearchSelectionCustomAdapter) {

    let SelectionAdapter = Utils.Decorate(
        MultipleSelection,
        Search
    );

    $('.inline-search-original').select2({
        selectionAdapter: SelectionAdapter
    });

    $('.inline-search-amd').select2({
        selectionAdapter: InlineSearchSelectionCustomAdapter
    });
});

.select2-selection__choice__remove {
    display: none !important;
}

.select2-container--focus .select2-autocomplete .select2-selection__choice {
    display: none;
}
