请教一下，不能更新父窗口的问题grid 数据问题，大侠请进来解说一下

Question

一、操作
1、点击新增入库
 
2、点击保存，父窗口数据不更新（已经确定数据库已经更新，并且已经确定调用了父窗口的方法refresh()） 
3、点击关闭，为什么这个时候父窗口数据出现才会出现呢？(尝试过直接reload父页面，还是无法更新grid页面的数据，只用关闭子窗口时候，数据才会更新过去)

 

二、代码
1、父页面代码，在onReady 方法中写了grid 实例化 和数据来源编写

 Ext.onReady(function(){ 
XXXXX
    infostore = new Ext.data.JsonStore({
     url:'../storage/stockIn.do?method=loadPlanDetails&simId=${planCode}',
     fields:[     
       {name:'sidAcceptancelistid',mapping:'sidAcceptancelistid'},
       {name:'unit'},
       {name:'spec'},
       {name:'sidBatchno',mapping:'sidBatchno'},
       {name:'sidId',mapping:'sidId'},
       {name:'sidInamount',mapping:'sidInamount'},
       {name:'sidInprice',mapping:'sidInprice'},
       {name:'sidInsum',mapping:'sidInsum'},
       {name:'sidMedicinecode',mapping:'sidMedicinecode'},
       {name:'medName',mapping:'medName'},
       {name:'sidMid',mapping:'sidMid'},
       {name:'sidValiddate',mapping:'sidValiddate'},
       {name:'sidWarningdate',mapping:'sidWarningdate'},
       {name:'sidFactoryId',mapping:'sidFactoryId'},
       {name:'sidFundSource'}
      ]
   });
  
 grid = new Ext.grid.GridPanel({
 store:infostore,
 columns:[    
  {name:'sidId',mapping:'sidId',dataIndex:'sidId',hidden:true},
  {name:'sidMid',mapping:'sidMid',dataIndex:'sidMid',header:'入库单主表ID',hidden:true},
  {name:'sidMedicinecode',mapping:'sidMedicinecode',dataIndex:'sidMedicinecode',header:'疫苗ID',hidden:true},
  //{name:'sidAcceptancelistid',mapping:'sidAcceptancelistid',dataIndex:'sidAcceptancelistid',hidden:true},
  {name:'medName',mapping:'medName',dataIndex:'medName',header:'疫苗',width:150},
  {header:'单位',dataIndex:'unit',width:60},
  {header:'规格',dataIndex:'spec',width:80},
  {name:'sidBatchno',mapping:'sidBatchno',dataIndex:'sidBatchno',header:'批号'},
  //{header:'资金来源',dataIndex:'sidFundSource',width:100},
  {name:'sidInamount',mapping:'sidInamount',dataIndex:'sidInamount',header:'入库数量'},
  {name:'sidInprice',mapping:'sidInprice',dataIndex:'sidInprice',header:'购进单价'},
  {name:'sidInsum',mapping:'sidInsum',dataIndex:'sidInsum',header:'总金额'},
  {name:'sidFactoryId',mapping:'sidFactoryId',dataIndex:'sidFactoryId',header:'生产厂家'},
  {name:'sidValiddate',mapping:'sidValiddate',dataIndex:'sidValiddate',header:'有效日期'},
  {name:'sidWarningdate',mapping:'sidWarningdate',dataIndex:'sidWarningdate',header:'失效报警日期'} 
 ],
 //title:'明细',
 height:380,
 bodyStyle:'width:100%;align:center',
 frame:true,
 iconCls:'icon-grid',
 stripeRows:true,
 tbar:[
  {text:'新增入库疫苗',handler:insertDetail1,iconCls:'add'},'-',
  {text:'修改',handler:update,iconCls:'edit'},'-',
  {text:'删除',handler:del,iconCls:'remove'}
 ]
 });
 infostore.load({callback:disableSelect}); 
 grid.addListener('rowdblclick', update);
 grid.render('grplist');
    sm = grid.getSelectionModel();
   
   refresh= function (){
  //alert("dd");
  //saveStockInm(1);
  //remove有反应，
  infostore.removeAll();
  //reload没有反应
  infostore.reload({callback:disableSelect});
  grid.addListener('rowdblclick', update);
  grid.render('grplist');
     sm = grid.getSelectionModel();
   //  window.location.reload();

  //alert("ddddd333");
}

2、父页面代码 弹出模态窗口

function insertDetail2(){ //selectFromAccList.jsp
 var simId=stockinForm.simId.value;
 var providerId=stockinForm.simProviderid.value;
 
 if(providerId==null||providerId==''){
  Ext.Msg.alert('提醒','请先选择供应单位!');
  return;
 }
 
 var val = window.showModalDialog('stockIn.do?method=toAccList&simId='+simId+'&providerId='+providerId,window,'dialogWidth:650px; dialogHeight:470px; status:0; scroll:0;help:0; resizable:1');
 if(val){
  //saveStockInm(1);
  //infostore.removeAll();
  //infostore.reload({callback:disableSelect});
 }
}

3、子页面代码 ， 调用 父窗口方法，数据不更新  parentWin.refresh();  parentWin.infostore.reload();
var parentWin=window.dialogArguments;
   function add(){ 
    if (!validate())
        return;
        
    Ext.Ajax.request({
     url:'../storage/stockIn.do?method=saveOneInDetail',
     form:'stockinForm',
     success:function(){
      returnValue=true;
      //window.close(); 
      
      parentWin.refresh();
      parentWin.infostore.reload(); 
        
     },
     failure:function(){Ext.MessageBox.alert('提示', '发生错误....');}
    });
   }
   

Answer 1

解决办法：在子窗口中加入这个方法，在add的时候，将该执行该方法。
//刷新父窗口；
[code="javascript"]
function refresh(){
Ext.Ajax.request({
parentWin.infostore.removeAll();
url:parentWin.infostore.url,
success:function(response){
var data = Ext.util.JSON.decode(response.responseText);
parentWin.infostore.loadData(data);

},
failure:function(){Ext.MessageBox.alert('提示', '发生错误....');}
});
}
