我有以下代码，当我回调服务器以重新加载网格时，我的下拉过滤器不会根据列数据刷新。

页面加载后，网格加载正常，下拉过滤器加载适当的数据，不包括处于取消或过期状态的报价。当用户单击 Canceled 复选框时，网格会重新加载，并且数据现在包括已取消状态。问题是状态名称下拉工具栏过滤器现在不包括取消的新状态（如果选择则过期）。从我在网上可以找到的内容来看，下拉过滤器似乎应该根据新数据重新加载。我错过了什么？

$(document).ready(function () {
    $("#ckRecentViewed").on('change', function (e) {
        loadGrid();
    });

    $("#ckCanceled").on('change', function (e) {
        loadGrid();
    });

    $("#ckExpired").on('change', function (e) {
        loadGrid();
    });

    $("input:radio:checked").data("chk", true);
    $("input:radio").click(function () {
        $("input[name='" + $(this).attr("name") + "']:radio").not(this).removeData("chk");
        $(this).data("chk", !$(this).data("chk"));
        $(this).prop("checked", $(this).data("chk"));
        $(this).button('refresh'); // in case you change the radio elements dynamically
        loadGrid();
    });

    $("#chkInMyStep").on('change', function (e) {
        loadGrid();
    });

    $('#dvWrapperFilter').on('click', function () {
        $("#dvFilters").slideToggle(function () {
            if ($('#imgHdrPlusMinus').attr('src').indexOf("plus") > 0) {
                $('#imgHdrPlusMinus').attr('src', $('#imgHdrPlusMinus').attr('src').replace("plus", "minus"));
            } else {

不确定 free-jqGrid 是如何工作的（我们支持 Guriddo jqGrid），但我认为您应该先销毁 filterToolbar，然后再重新创建它。创建过滤器工具栏时，设置一个标志，表明其存在。对它的任何其他调用都不会执行。所以也许要工作，你应该在创建它之前调用destroyFilterToolbar。

beforeProcessingHandler1 = function (data) {
....
    $this.jqGrid("destroyFilterToolba");
    $this.jqGrid("filterToolbar",{...});
}

就个人而言，也许我会使用 jQuery 函数直接在工具栏中刷新选择值，但这取决于您的实现。

我最终切换到 Guriddo jqGrid，因为我找到了更多文档和有用的示例并且能够解决我的问题。感谢您的帮助托尼。
