Question

我的JQuery自动完成功能几乎正常。插入“Af”后，如果我按下KeyDown，我正确地得到“阿富汗”。但是，我永远无法看到所有国家/地区的下拉列表。我错过了一些自动填充选项吗？

我的代码：

@Html.TextBox("Countries", "", new { @class = "COUNTRIES", @placeholder = "Insert Country..."}) 

<script src="https://code.jquery.com/jquery-1.9.1.js"></script>

<script>
    $(function () {
        var countriesList = ["Afghanistan", "Albania", "Algeria"]
        $(".COUNTRIES").autocomplete({ source: countriesList });
    });
</script>
