Question

我一直在努力让jqGrid中的动态分组工作。数据正在通过jqGrid ajax数据调用以XML格式正确排序和返回。

当我在特定列上动态启用分组时，会显示一个标题为“未定义”的组？

我已经尝试了我能想到的一切，但没有成功:(任何建议都会非常感激。

我的jqGrid JavScript代码摘录如下所示（注意：在此示例中，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';
 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');
  });
 });

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

Answer 1

问题解决了......“ColModel”数组的“name”值设置错误。（我使用了列标题字符串而不是实际的数据库表字段名。）

jqGrid分组返回“未定义”组标题
