ExtJs中gridpanel分组后组名排序实例代码

var DescGroupingStore=Ext.extend(Ext.data.GroupingStore, {
groupDir : 'ASC',
groupBy : function(field, forceRegroup, direction) {
    direction=direction ? (String(direction)
              .toUpperCase()=='DESC' ? 'DESC' : 'ASC')
              : this.groupDir;
    if (this.groupField==field
           this.groupDir==direction && !forceRegroup) {
          return;
   }
   this.groupField=field;
   this.groupDir=direction;
   if (this.remoteGroup) {
       if (!this.baseParams) {
          this.baseParams={};
       }
       this.baseParams['groupBy']=field;
          this.baseParams['groupDir']=direction;
       }
       if (this.groupOnSort) {
            this.sort(field, direction);
            return;
       }
       if (this.remoteGroup) {
            this.reload();
       } else {
            var si=this.sortInfo || {};
            if (si.field !=field || si.direction !=direction) {
                this.applySort();
            } else {
                this.sortData(field, direction);
            }
            this.fireEvent('datachanged', this);
        }
    },
    applySort : function() {
        Ext.data.GroupingStore.superclass.applySort.call(this);
        if (!this.groupOnSort && !this.remoteGroup) {
            if (this.groupField !=this.sortInfo.field
                    || this.groupDir !=this.sortInfo.direction) {

关于ExtJs中gridpanel分组后组名排序实例代码的用户互动如下：

　　相关问题：加分! Extjs5.0版本中Ext.grid.property.Grid组件...

　　答：你是想让那一列不允许排序么？列属性里有个sortable，新建的时候设为false 比如 Ext.create('Ext.data.Store', { storeId:'employeeStore', fields:['firstname', 'lastname', 'seniority', 'dep', 'hired'], data:[ {firstname:"Michael", last... >>详细

　　相关问题：EXT如何通过代码对GridPanel某一列进行排序，我想...

　　答：grid.store.sort('id','ASC');//或者DESC >>详细

　　相关问题：extjs gridpanel 为什么排序不可用

　　答：Column 中加上 sortable : true //是否可排序 >>详细
