Ext radiogroup 动态加载数据问题
代码如下：
var formpanel=new Ext.FormPanel({ labelAlign: 'center', renderTo: document.body, layout:'form', frame:true, title: '知识库管理(无线宽带导航页面推送)', bodyStyle:'padding:5px 5px 0', anchor:'95%', items: [ { xtype: 'radiogroup', name: 'biztype', width: 220, columns: 3, fieldLabel: '业务类别', //store:dataitems:getData() }] }); function getData(){ var conn = new Ext.data.Connection(); conn.request({ // url:'../jfoss/usersearchinfoinitt.action', //数据地址 url:'./combobox.jsp', //数据地址 // url: '', success: function(response) { itemArray = Ext.util.JSON.decode(response.responseText); Ext.getCmp('id').items=itemArray; } }); }
combobox.jsp内容如下：[
{boxLabel: 'type1',name:'type1', inputValue: '01'},
{boxLabel: 'type2',name:'type2', inputValue: '02'},
{boxLabel: 'type3',name:'type3', inputValue: '03'},
{boxLabel: 'type4', name:'type4',inputValue: '04'}
]
可是firefox调试说：this.items is undefined 肯定是数据获取问题 或者items:getData()这块有问题，
高手帮帮忙啊？急死我了
[解决办法]
给其初始的rdaio,然后返回数据后删掉它，创建新的。
