其中action中方法代码如下：
public String getPoqutityGridByPoId(){
PoqutityGridForm pf = purchaseOrderService.getPoqutityByPoIdgrid(detailPoId);
if(pf==null){
this.setJsonString("{result:[],totalRecord:0}");
return "fail";
}
List columnList = pf.getColNames();
List dataList = pf.getColValues();
JSONArray column = JSONArray.fromObject(columnList);
JSONArray data = JSONArray.fromObject(dataList);
String message ="{column:" +column.toString()+", data:"+data.toString()+"}";
this.setMessage(message);
this.setJsonString("{success:true, msg:'"
+ this.getMessage().toString() + "'}");
return this.SUCCESS;
}
在js中这样获得数据：
var cm;
var ds;
Ext.ajax.request({
url:'getPoqutityGridByPoId.do?detailPoId='+poId,
method:'post',
success:
function(response,options){
alert(response.responseText);
var json = Ext.util.JSON.decode(response.responseText);
var realjson = Ext.util.JSON.decode(json.msg);
cm = new Ext.grid.ColumnModel(realjson.column);
ds = new Ext.data.JsonStore({
data:realjson.data,
fields:['color','col1','col2','col3','col4','col5','col6','col7','col8','col9','col10','total']
});
},
failure:
function (){
}
});
后面生成grid
var podetailgrid = new Ext.grid.GridPanel({
title:"",
cm:cm,
ds:ds,
viewConfig: {
forceFit:true
},
frame:true,
collapsible: true,
animCollapse: false,
iconCls: 'icon-grid'
});
最后显示grid
var pnl = new Ext.Viewport({
layout: 'border',
items: [
{
region : 'north',
autoScroll : true,
border:false,
height: 720,
items: basePanel
},
{
region : 'center',
autoScroll : true,
border:false,
layout: 'fit',
items: podetailgrid
},
{
region : 'south',
autoScroll : true,
border:false,
height: 300,
minSize: 300,
maxSize: 600,
items: grid
}
]
});
在获取数据阶段我alert过，数据是有的，但是在生成grid的时候报出q is undefined的错误，请问到底应该怎么做啊？尝试了网上的好几个方法，快崩溃啦，求大侠们帮忙想想办法~~
