jqGrid 过滤器下拉列表不适用于特殊字符

Question

当使用 jqGrid 内置的列搜索功能时，dropdwonlist 拒绝显示特殊字符，例如 ç、È 等。由于某种原因，它们被分成两行。这意味着如果我们输入一个词 "Dfëstuç" ，下拉列表或选项列表将生成如下：

Dfë
未定义
学
未定义

我的代码如下：

@model WS.ViewModels.CaseViewModel
@{
    ViewBag.Title = "";
    Layout = "~/Views/Shared/_Layout.cshtml";

<meta charset="utf-8"> 


    string idVendbanimiSelectValues = ":";


    foreach (var item in Model.NomenklaturaVendbanimiDropDownListData.OrderBy(n => n.IdVendbanimi))
    {
        idVendbanimiSelectValues += ";" + item.IdVendbanimi + ":" + item.EnPershkrimi;
    }
}

@section AdditionalCss {
    @Styles.Render("~/Content/Styles/ui.jqgrid.min.css")
}

@section AdditionalJavaScript {
    @Scripts.Render("~/bundles/jqgrid")
    @Scripts.Render("~/Scripts/jqgrid-listsearch.js")
    @Scripts.Render("~/Scripts/jquery.searchFilter.min.js")

    <script type="text/javascript">
        $(function () {
            var idVendbanimiSelectValues = "@idVendbanimiSelectValues";

            $('#list-grid').jqGrid({
                url: '/Lenda/GridDataWithFilters/',
                datatype: 'json',
                mtype: 'GET',
                colNames: ['CaseId','IdVendbanimi'],
                colModel: [
                    { name: 'CaseId', index: 'CaseId', align: 'right' },
                    { name: 'IdVendbanimi', index: 'IdVendbanimi', align: 'left', stype: 'select', edittype: 'select', editoptions: { value: idVendbanimiSelectValues },  autoencode: false }
                ],
                pager: $('#list-pager'),
                rowNum: 10,
                rowList: [5, 10, 20, 50],
                sortname: 'CaseId',
                sortorder: "asc",
                viewrecords: true,

                width: '1200',
                ignoreCase: true,
                autoencode: true,

            }).jqGrid('navGrid', '#list-pager', { edit: false, add: false, del: false, search: false, refresh: false });

            $('#list-grid').jqGrid('filterToolbar', { stringResult: true, searchOnEnter: false, beforeSearch: function () {
                // verify entered data before searching
                var postData = $('#list-grid').jqGrid('getGridParam', 'postData');
                var searchData = $.parseJSON(postData.filters);
                var isThereValidationErrors = false;
                var validationErrors = "";

                for (var iRule = 0; iRule < searchData.rules.length; iRule++) {
                    var enteredValue = searchData.rules[iRule].data;

                    if (searchData.rules[iRule].field == "CaseId" && !isNumeric(enteredValue)) {
                        validationErrors += "  Id Lenda must be a valid number.";
                        isThereValidationErrors = true;
                    }
                }

                if(isThereValidationErrors)
                    alert($.trim(validationErrors));

                return isThereValidationErrors;
            }
            });
        });
    </script>

您的 JSON 数据是否正确进行了 UTF-8 编码？例如：

ë 字符应该用两个字节编码，0xC3 0xAB。
JSON 数据可能需要一个 UTF-8 前导码，0xEF 0xBB 0xBF。
