為什麼我的 jqGrid 編輯表單中的狀態選擇框選項值不正確？

<code class="javascript">var countries = { '1': 'US', '2': 'UK' };
var states = { '1': 'Alabama', '2': 'California', '3': 'Florida', '4': 'Hawaii', '5': 'London', '6': 'Oxford' };
var statesOfCountry = {
    1: { '1': 'Alabama', '2': 'California', '3': 'Florida', '4': 'Hawaii' },
    2: { '5': 'London', '6': 'Oxford' }
};

var resetStatesValues = function () {
    grid.setColProp('State', { editoptions: { value: states} });
};

$("#list").jqGrid({
    data: mydata,
    datatype: 'local',
    colModel: [
        { name: 'Name', width: 200 },
        { 
            name: 'Country', 
            width: 100, 
            editable: true, 
            formatter: 'select',
            edittype: 'select', 
            editoptions: {
                value: countries,
                dataInit: function (elem) {
                    setStateValues($(elem).val());
                },
                dataEvents: [
                    { type: 'change', fn: function (e) { changeStateSelect($(e.target).val(), e.target); } },
                    { type: 'keyup', fn: function (e) { $(e.target).trigger('change'); } }
                ]
            }
        },
        {
            name: 'State',

                grid.restoreRow(lastSel);
            }
            lastSel = id;
        }
    },
    ondblClickRow: function (id, ri, ci) {
        if (id &amp;&amp; id !== lastSel) {
            grid.restoreRow(lastSel);
            lastSel = id;
        }
        resetStatesValues();
        grid.editRow(id, true, null, null, 'clientArray', null,
                        function (rowid, response) {  // aftersavefunc
                            grid.setColProp('State', { editoptions: { value: states} });
                        });
        return;
