Extjs3.x gridPanel row data moving up and down example code

Ext3.x is also new to me and I am not familiar with it. I'll record it in my spare time for easy reference next time, and I hope it can help my colleagues. Just mess with the code!

rowUp : function() {//上移
var records =  this.gridPanel.getSelectionModel().getSelections();//得到选中所有行
for(var i in records)//遍历所选的所有行
{
var record = records[i];//每行的数据（记录此数据）
var index = this.gridPanel.getStore().indexOf(record);//数据所在位置
if(0>=index)
{
return;//不可移动
}
var data = record.data; 
var NewRecord = new Ext.data.Record({ //记录数据，remove&和insert方法是记录数组（我他妈不知道啥玩意）
itemName:data.itemName, //这里面的参数取gridPanel列表中record的定义
itemIndex:data.itemIndex,
maxScore:data.maxScore,
minScore:data.minScore,
itemType:data.itemType
            }); 
this.gridPanel.getStore().removeAt(index);//删除当前所选行数据
this.gridPanel.getStore().insert(index-1,NewRecord);//将记录数据插入到所删除数据位置的上一位置
this.gridPanel.getView().refresh();
this.gridPanel.getSelectionModel().selectRow(index-1,index-1);
}
},
 
rpwDown : function() {//下移
var records =  this.gridPanel.getSelectionModel().getSelections();//得到选中所有行
var num = this.gridPanel.getStore().getCount();
for(var i in records)//遍历所选的所有行
{
var record = records[i];//每行的数据（记录此数据）
var index = this.gridPanel.getStore().indexOf(record);//数据所在位置
if(this.gridPanel.getStore().getCount()-1<=index||0>index)
{
return;//不可移动
}
var data = record.data; 
var NewRecord = new Ext.data.Record({ 
itemName:data.itemName,
itemIndex:data.itemIndex,
maxScore:data.maxScore,
minScore:data.minScore,
itemType:data.itemType
            }); 
this.gridPanel.getStore().removeAt(index);//删除当前所选行数据
this.gridPanel.getStore().insert(index+1,NewRecord);//将记录数据插入到所删除数据位置的下一位置
this.gridPanel.getView().refresh();//刷新（不知道刷的啥）
this.gridPanel.getSelectionModel().selectRow(index+1,index+1);
 
}
//this.gridPanel.getStore().reload();
},

Just throw event calls into the two functions. It works fine, but there will be bugs (you will know it after using it, but I don’t know how to solve it now), and moving the multi-select data up or down is OK.
