c# - 当我在表头 JQuery 上选择排序时，下拉选择不会预先附加

Question

我在表格上方有一个下拉列表，当您选择下拉列表时，选择不会预先附加选择。当我单击下拉菜单然后单击我的表头对它们进行排序时，下拉选择会丢失。

落下

@Html.DropDownList("TenantList", (IEnumerable<SelectListItem>)ViewBag.TenantList, new { id = "ddlSociety", @class = "form-control" })

桌子

<th class="sorting text-left hidden-xs hidden-sm @Html.SortTitleItem("SongId", Model.PagingInfo.SortPropertyName, Model.PagingInfo.SortAscending)">
                    <a href="@Url.Action("VerifiedSongs", "SongsManagement", new
                    {
                        songid = songId,
                        page = 1,
                        take = Model.PagingInfo.Take,
                        sortBy = "SongId",
                        sortAsc = Model.PagingInfo.SortPropertyName != "SongId" || !Model.PagingInfo.SortAscending
                    })" data-container="body" data-toggle="tooltip" title="Sort by Song ID">Song ID</a>
                </th>

jQuery

 @* Sorting Async Partial Handling *@
    $(document).on("click",
        "#tableHeader a",
        function()
        {
            loadPartialPage($(this).attr("href"));
            return false;
        });
    });

有没有办法让它预先附加选择，同时点击表格标题上的排序？我不确定这是否是 JQuery 问题？
