解決辦法

<select id="Category_select" name="ManagementType" lay-verify="" lay-search>
<option value="" selected="selected"></option>
</select>

    
  layui.use(['form', 'layer'], function () {
            var $ = layui.jquery
                , element = layui.element; //Tab的切換功能，切換事件監聽等，需要依賴element模塊
            var form = layui.form;
            $.ajax({
                type: "POST",
                url: "/Personnel/DepartParent",
                data: null,
                dataType: 'json',
                success: function (result) {
                    var datas = "";
                    var data = result.data;
                    for (var i = 0; i < data.length; i++) {
                        debugger;
                        datas += "<option value='" + data[i].Code + "'>" + data[i].DeptName  + "</option>";
                    }
                    $('#Category_select').append(datas);
                    form.render('select');
                },
                error: function (error) {
                    $.modal.alertWarning("獲取模版數據失敗");
                }
            });
        });
