将部分代码贴上：
SearchDataFrom_BS_YSLZNEW = function(actTab) {
this.title = "查询窗口";
var myPanel=new SearchPanel(actTab);
var onClose = function() { Ext.getCmp('searchdata').close(); }
// var onSearch=function(){
// DCI.Application.data.getSJ(grid.casenum, function(json, scope) {
// if (json && json != '') {
// var data = Ext.util.JSON.decode(json);
//// var tempText = data[0].id;
//// Ext.getCmp('outputTextArea').setValue(json.toString());
//// alert(data.length);
// var len = data.length;
// for(var i=1;i<len;i++)
// {
// if( grid.casenum.getValue()==data[i].CASENUM)
// {
// alert('查询成功！！');
// }
// else
// {
// alert('受理编号不存在，请核实后重新输入');
// }
// }
//
// }
// else
// {
// alert('error!');
// }
// },actTab);
// }

SearchPanel = function(actTab){
this.callback = function(json, scope) {
if (json != null && json != "") {
var data = Ext.util.JSON.decode(json);
var jsonStr = new Ext.util.JSON.decode(json);
var store = new Ext.data.JsonStore({ data: jsonStr, fields: ['CASENUM', 'UNITADD','CASEDD','SQR','LXDH'] });
}
}
}

var queryForm=new Ext.form.FormPanel({
id:"queryForm",
renderTo:"SearchPanel",
frame:true,
region:"center",
// labelWidth:80,
border:false,
labelAlign:'right',
frame:true,
// store:jsonStr,
items:[
{xtype:'textfield',fieldLabel:'受理编号：',name:'casenum',id:'casenum',allowBlank:false,height:"auto",vtype:'specialChar'},
{xtype:'textfield',buttonLabel:'单位地址：',name:'unitdd',id:'unitdd',height:"auto",vtype:'specialChar'},
{xtype:'textfield',fieldLabel:'项目地点：',name:'caseadd',id:'caseadd',height:"auto",vtype:'specialChar'},
{xtype:'textfield',fieldLabel:'申请人：',name:'sqr',id:'sqr',height:"auto",vtype:'specialChar'},
{xtype:'textfield',fieldLabel:'联系电话：',name:'lxdh',id:'lxdh',height:"auto",vtype:'specialChar'}
]
// ,
// buttons:[{text:'查找',buttonAlign:"right", handler:onSearch}]
});

SearchDataFrom_BS_YSLZNEW.superclass.constructor.call(this, {
id: 'searchdata',
title: '查询相关数据',
closable: true,
height: 320,
width: 410,
border: false,
plain: true,
resizable: false,
items:[myPanel],
buttons: [ {
text: "关闭",
handler: onClose
}]
});
}
Ext.extend(SearchDataFrom_BS_YSLZNEW, Ext.Window, {});

可是连面板都显示不出来，是何缘故，请高手帮忙
