this.fields.get(c) is undefined

今天在做项目的时候碰到这个问题,和大家一起分享:

源代码:大家一定需要注意我的Store中的sortInfo:

<script type="text/javascript"> Ext.onReady(function(){ Ext.QuickTips.init(); //别名 var xg=Ext.grid; //创建一个ArrayReader var reader=new Ext.data.ArrayReader({},[ {name:"name",type:"string"}, {name:"age",type:"int"}, {name:"empno",type:"int"}, {name:"sex",type:"int"}, {name:"birthday",type:"date",dateFormat:"n/j h:ia"}, {name:"salary",type:"float"}, {name:"deptno",type:"int"} ]); //创建一个store var store=new Ext.data.GroupingStore({ reader:reader, data:xg.dummyData, sortInfo:{field:"company",direction:"ASC"}, groupField:"deptno" //根据部门来分组 }); //name的renderer function nameCls(val){ if(val.length>2){ return "<span stype='color:red;'>"+val+"</span>"; } return "<span stype='color:blue;'>"+val+"</span>"; } //age的Cls function agCls(val){ if(val>25){ return "<span stype='color:red;'>"+val+"</span>"; } return "<span stype='color:green;'>"+val+"</span>"; } //创建一个gridPanel var grid=new xg.GridPanel({ store:store, columns:[ {header:"姓名",width:20,sortable:true,renderer:nameCls,dataIndex:"name"}, {header:"年龄",width:40,sortable:true,renderer:agCls,dataIndex:"age"}, {id:"empno",header:"编号",width:60,sortable:true,dataIndex:"empno"}, {header:"性别",width:20,sortable:true,dataIndex:"sex"}, {header:"生日",width:50,sotrable:true,renderer:Ext.util.Format.dateRenderer("m/d/Y"),dataIndex:"birthday"}, {header:"工资",width:30,sortable:true,renderer:Ext.util.Format.usMoney,dataIndex:"salary"}, {header:"部门编号",width:50,sortable:true,dataIndex:"deptno"} ], view:new Ext.grid.GroupingView({ forceFit:true, groupTextTpl:"{text} ({[values.rs.length]} {[values.rs.length>1 ? 'Items' : 'Item']})" }), frame:true, width:700, height:450, collapsible:true,//True表示为面板是可收缩的，并自动渲染一个展开/收缩的轮换按钮在头部工具条。false表示为保持面板为一个静止的尺寸 animCollapse:true,//True 表示为面板闭合过程附有动画效果（默认为true，在类 Ext.Fx 可用的情况下）。 title:"雇员信息", iconCls:"icon-grid", fbar:["->",{ text:"clear Groping", iconCls:"icon-clear-group", handler:function(){ store.clearGouping(); } }], renderTo:document.body }); }); //数据 Ext.grid.dummyData=[ ["张三00",12,1001,1,"1990-05-20",3000,50], ["张三01",16,1002,0,"1990-05-21",3000,20], ["张三02",19,1003,1,"1990-05-22",3000,20], ["张三03",25,1004,1,"1990-05-23",3000,10], ["张三04",22,1005,1,"1990-05-24",3000,30], ["张三05",24,1006,1,"1990-05-25",3000,20], ["张三06",23,1007,0,"1990-05-26",3000,60], ["张三07",21,1008,0,"1990-05-27",3000,90], ["张三08",25,1009,0,"1990-05-28",3000,10], ["张三09",28,1010,1,"1990-05-29",6000,20], ["张三20",26,1011,0,"1990-05-20",2000,50], ["张三21",29,1012,0,"1990-06-20",8000,40], ["张三22",22,1013,1,"1990-01-20",3000,50], ["张三23",28,1014,0,"1990-02-20",3000,60], ["张三24",21,1015,1,"1990-08-20",3000,50] ]; </script>

错误就出现在那里,没有company列但是,我却给company列排序所以报错,

找了很长时间,特地贴出来,不知道对大家有没有帮助.
