Extjs4之Grid监听排序事件

 var grid = Ext.create('Ext.grid.Panel', {
     border: true,
     stripeRows: true,
     columns: [
         { xtype: 'rownumberer' },
         { text: '学期', dataIndex: 'schoolTerm', align: 'center', flex: 1 }
     ],
     selModel: sm,
     store: studentStore,
     columnLines: false,
     loadMask: { msg: '数据加载中，请稍候...' },
     listeners: {
         //添加排序改变事件
 p;           sortchange: function (ct, column, direction, eOpts) {
             var title = column.textEl.getHTML();//获取列表头的文本
             if (title == "学期") {
                 var sortType = Ext.util.Format.uppercase(direction);//获取排序方式“DESC”或“ASC”
                 if ("DESC" == sortType) {
                     studentStore.sort('schoolTermId', 'DESC');
                 } else {
                     studentStore.sort('schoolTermId', 'ASC');
                 }
                 studentStore.load({//加载数据
                     scope: this,
                     callback: function (records, operation, success) {
                         var responseData = studentStore.getProxy().getReader().rawData;
                         if (typeof (responseData) == "undefined") {
                             return;
                         }
                         var responseMsg = responseData.msg;
                         var responseFlag = responseData.success;
                         if (responseFlag != null && responseFlag == false) {
                             Ext.Msg.alert('温馨提示', '您好，查询信息失败！' + responseMsg);
                         }
                     }
                 });
             }
         }
     }

 });
