RadioGroup中和fireEvent

Question

我有一個簡單的RadioGroup中類：

 
TestRadioGroup = Ext.extend (Ext.form.RadioGroup, { 
     fieldLabel: 'Test', 
     listeners: { 
      change: function(el,val) { 
       alert(val); 
      } 
     }, 
     constructor: function(config) { 
      this.items = []; 
      this.items.push ({boxLabel: 'Test1', name: 'test', inputValue: 2 }); 
      this.items.push ({boxLabel: 'Test2', name: 'test', inputValue: 1 }); 
      this.items.push ({boxLabel: 'Test',name: 'test', inputValue: 0 } ); 
//   fireEvent('change') 
      TestRadioGroup.superclass.constructor.call(this); 
     } 
}); 

我想

fireEvent('change')

爲這個項目inputValue的1怎麼辦呢？

Answer 1

也許類似的東西

TestRadioGroup.fireEvent('change', TestRadioGroup, checkedRadioObj)
