免费的jqgrid不重载Edges上的数据。

Question

我在我的页面中添加了一个jqGrid表，在这里我需要添加寄存器，在我做了一些处理后，我需要重新加载de数据，所有的都是本地的，没有服务器通信，这是我的代码。

$(function () {

    $.extend(true, $.jgrid.inlineEdit, {
        beforeCancelRow: function (options, rowid) {
            $(this).jqGrid('saveRow', rowid);
            $(this).setCell(rowid, 'TipoEtiqueta', '', '', { 'title': null });  
            return false;
        }
    });

    L_Grid.jqGrid({
        loadonce: false,
        data: notas,
        datatype: "local",
        refresh: true,
        colNames: ['Código Etiqueta', 'Tiempo (hh:mm:ss)', 'Descripción', 'Privada', 'Eliminar'],
        colModel: [
            {
                name: 'Codigo', index: 'Codigo', hidden: true, search: false
            },
            {
                name: 'TiempoMilisegundos', index: 'TiempoMilisegundos', align: "center", search: false,
                formatter: function (cellvalue, options, rowObject) {
                    return TimeFormat(cellvalue)
                },
                cellattr: function (rowId, val) {
                    return 'aria-label="Tiempo de la etiqueta ' + TimeFormat(val) + '" title="Tiempo de la etiqueta" onclick="navegarEtiqueta(' + val + ')" tabindex="0"';
                }
            },
            {
                name: 'Descripcion', index: 'Descripcion', align: "center", width: 320, editable: true, editoptions: { required: false, maxlength: 255, "class": "descripcion-etiqueta", list: "etiquetasPredefinidas" }, classes: "descripcion-etiqueta",
                cellattr: function (rowId, val) {
                    return 'tabindex="0"';
                }
            },
            {
                name: 'TipoEtiqueta', index: 'TipoEtiqueta', align: "center", search: false, editable: true,
                formatter: function (cellvalue, options, rowObject) {
                    var titulo = cellvalue ? "Privada": "Pública";
                    return '    <label class="switch" title="' + titulo +'">'
                        + '     <input tabindex="0" type="checkbox" ' + ValidarCheck(cellvalue) + ' aria-disabled="true" disabled aria-label="Indicador de etiqueta privada" role="switch">'

                        var V_RowData = V_Localdata[L_Grid.jqGrid('getGridParam', '_index')[options.rowId]];

                        return $('<label class="switch">'

        ],
        onSelectRow: function (rowid, status, e) {
            var $self = $(this), savedRow = $self.jqGrid("getGridParam", "savedRow");

            if (savedRow.length > 0 && savedRow[0].id !== rowid) {

                $self.setCell(savedRow[0].id, 'TipoEtiqueta', '', '', { 'title': null });

    $(window).bind("resize", function () {
        L_Grid.jqGrid("setGridWidth", L_Grid.closest(".container").width());
    }).triggerHandler("resize");

    $("#txtBusqueda").on("input", function () {
        var savedRow = L_Grid.jqGrid("getGridParam", "savedRow");

        if (savedRow.length > 0) {

            rules = [],
            searchText = $(this).val(),

            i,

    });

    L_Grid.jqGrid('bindKeys', {

            L_Grid.jqGrid('editRow', rowid, true, null, null, null, {}, function () {
                setTimeout(function () {
                    L_Grid.focus();

});


function ReloadNotsGrid(nots) {

L_Grid.jqGrid('setGridParam',
    {
        datatype: 'local',
        data: nots
    })
    .trigger("reloadGrid");}

当我调用 ReloadNotsGrid 我在Edges上得到这个异常。

jquery.jqgrid.min.js 0x800a13b5 - JavaScript运行时错误。在严格模式下不允许向只读属性赋值

Answer 1

我找到了解决办法，我把数据以字符串的形式 "原始 "发送，我需要做的是 jQuery.parseJSON (notes)但我得到的异常有点误导人。其他罕见的事情是，我只在MS Edges (Microsoft EdgeHTML 18.18363, Microsoft Edge 44.18362.449.0)中得到这个异常，在chrome (Version 81.0.4044.138 (Official Build) (64-bit))中，它工作得很好。

代码最终看起来像这样。

function ReloadNotsGrid(nots) {

var dataToLoad = jQuery.parseJSON(nots);

L_Grid.jqGrid('setGridParam',
    {
        datatype: 'local',
        data: dataToLoad
    })
    .trigger("reloadGrid");
}
