我一直在努力獲得在jqGrid中工作的動態分組。數據通過jqGrid ajax數據調用正確排序並以XML格式返回。jqGrid分組返回「undefined」組標題
當我動態啓用特定列上的分組時，會顯示一個標題爲「未定義」的組？
我用盡了一切我能想到的，但沒有成功:(任何建議，將不勝感激
我的jqGrid JavScript代碼摘錄如下，（注：在這個例子中，網格列通過閱讀Ajax調用，並存儲在被稱爲「元數據」的變量。）
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');
});
});
這裏是排序的數據的一個例子由（澳大利亞）的狀態列分組，即「ACT」，「FIXME」之後返回，「 NSW「
