jqGrid分组返回“；“未定义”；组标题

我一直在努力让动态分组在jqGrid中工作。通过jqGrid ajax数据调用，数据被正确排序并以XML格式返回

当我在特定列上动态启用分组时，将显示标题为“undefined”的单个组

我已经尝试了我能想到的一切，但没有成功：（任何建议将不胜感激

我的jqGrid JavScript代码摘录如下所示（注意：在本例中，网格列通过ajax调用读取，并存储在名为“MetaData”的变量中）

var XmlFile='CC1533C4-239E-4CF7-9D3E-03F87E75F445'；
变量SessionID='B656C7A5198E472F901399FF81196C14'；
var InitGridUrl='/base/_resource/Widgets/jqGrid/initgrid.php'+SessionID+XmlFile；//此web服务将返回报表表元数据
ObjectCount=函数（\u对象）
{
尝试
{
var计数=0；
for（变量属性在_对象中）
{
if（_Object.hasOwnProperty（property））{count++；}
}
返回计数；
}
捕获（e）{}
返回-1；
};
jQuery（文档）.ready（函数（）
{
getJSON（InitGridUrl，函数（元数据）//通过ajax调用将网格列信息读入“元数据”
{
var colNames=new Array（），colModel=new Array（）；
var LastModified=新日期（元数据['LastModified']*1000）；
每个（元数据['Structure']，函数（FieldTypeId，Field）
{
colNames.push（字段['Name']）；
if（colNames.length==1）colModel.push（{name:Field['name']，index:Field['Field']，width:'35'，align:Field['align']，sortable:false，search:false，key:true}）；
其他的
{
push（{name:Field['name']，index:Field['Field']，align:Field['align']，sortable:true}）；
jQuery（'#selectgroup'）.append（jQuery（''）.attr（'value'，Field['Field']）.text（Field['Name']）；
}
});
jQuery（“网格”）.jqGrid
({
网址：'http://localhost/base/_resource/Widgets/jqGrid/getdata.php',
数据类型：“xml”，
mtype:'获取'，
colNames:colNames，
colModel:colModel，
寻呼机：“#寻呼机”，
rowNum:20，
行列表：[10,20,30,40,50]，
sortname:colModel[0]['index']，
排序器：“asc”，
viewrecords：是的，
gridview：没错，
标题：元数据['Title']+'[Last Modified:'+LastModified.ToLocalString（）.split（'GMT'）[0]+']，
altclass:“AltRowClass”，
阿尔特罗斯：是的，
身高：400，
宽度：“自动”，
自动宽度：正确，

行数：false，

groupingView:{groupField:[colModel[0]['index']]，groupColumnShow:[true]，groupText:['{0}-{1}项]，groupCollapse:false，groupOrder:['asc']，groupSummary:[false]，groupDataSorted:true}
});
jQuery（“#grid”）.jqGrid（'navGrid'，'#pager'，{edit:false，add:false，del:false}，{}，{}，{}，{multipleSearch:true，multipleGroup:true，showQuery:true}）；
jQuery（“#selectgroup”）.change（函数（）
{
var vl=jQuery（this.val（）；
if（vl）
{
if（vl==“clear”）{jQuery（#grid”）.jqGrid（'groupingRemove'，true）；}
else{jQuery（#grid”）.jqGrid（'groupingGroupBy'，vl）；}
}
});
jQuery（'td#refresh#u grid'）。在（jQuery（'#selectgroup'））之后；//在jqGrid页脚中找到分组下拉列表
jQuery（'#selectgroup'）.css（'visibility'，'visible'）；
});
});

以下是按（澳大利亚）州列分组后返回的排序数据示例，即“ACT”、“FIXME”、“NSW”

问题已解决…我错误地设置了“ColModel”数组的“name”值。（我使用了列标题字符串而不是实际的数据库表字段名。）

 var XmlFile = 'CC1533C4-239E-4CF7-9D3E-03F87E75F445';
 var SessionID = 'B656C7A5198E472F901399FF81196C14';

 var InitGridUrl = '/base/_resource/Widgets/jqGrid/initgrid.php' + SessionID + XmlFile;  // This web service will return the Report Table Metadata

 ObjectCount = function(_Object)
 {
  try
  {
   var count = 0;
   for (var property in _Object)
   {
    if (_Object.hasOwnProperty(property)) {count++;}
   }
   return count;
  }
  catch (e) {}

  return -1;
 };

 jQuery(document).ready(function()
 {
  jQuery.getJSON(InitGridUrl, function(MetaData)  // Read grid column info into "MetaData" via an ajax call
  {
   var colNames=new Array(), colModel=new Array();

   var LastModified = new Date(MetaData['LastModified'] * 1000);

   jQuery.each(MetaData['Structure'], function(FieldTypeId, Field)
   {
    colNames.push(Field['Name']);
    if (colNames.length == 1) colModel.push({name:Field['Name'], index:Field['Field'], width:'35', align:Field['Align'], sortable:false, search:false, key:true});
    else
    {
     colModel.push({name:Field['Name'], index:Field['Field'], align:Field['Align'], sortable:true});
     jQuery('#selectgroup').append(jQuery('<option></option>').attr('value', Field['Field']).text(Field['Name']));
    }
   });

   jQuery("#grid").jqGrid
   ({
     url: 'http://localhost/base/_resource/Widgets/jqGrid/getdata.php',
     datatype: 'xml',
     mtype: 'GET',
     colNames:colNames,
     colModel :colModel,
     pager: '#pager',
     rowNum:20,
     rowList:[10,20,30,40,50],
     sortname: colModel[0]['index'],
     sortorder: 'asc',
     viewrecords: true,
     gridview: true,
     caption: MetaData['Title'] + ' [Last Modified: ' + LastModified.toLocaleString().split(' GMT')[0] + ']',
     altclass: 'AltRowClass',
     altRows: true,
     height: 400,
     width:"auto",
     autowidth: true,
     shrinkToFit: true,
     rownumbers: false,
     grouping: false,
     groupingView : {groupField : [colModel[0]['index']], groupColumnShow : [true], groupText : ['<b>{0} - {1} Item(s)</b>'], groupCollapse : false, groupOrder: ['asc'], groupSummary : [false], groupDataSorted : true}
   });

   jQuery("#grid").jqGrid('navGrid','#pager', {edit:false,add:false,del:false}, {}, {}, {}, {multipleSearch:true, multipleGroup:true, showQuery:true});

   jQuery("#selectgroup").change(function()
   {
    var vl = jQuery(this).val();
    if(vl)
    {
     if(vl == "clear") {jQuery("#grid").jqGrid('groupingRemove',true);}
     else {jQuery("#grid").jqGrid('groupingGroupBy',vl);}
    }
   });

   jQuery('td#refresh_grid').after(jQuery('#selectgroup'));  // locate grouping droptdown list in jqGrid footer
   jQuery('#selectgroup').css('visibility', 'visible');
  });
 });
