Extjs radiogroup setValue

Question

在我的表格中，放射线组看起来像这样

              {
                xtype: 'radiogroup',
                vertical: false,
                fieldLabel: ' ',
                labelSeparator: ' ',
                reference: 'radiofield',
                val: 1,
                items: [
                    {
                        boxLabel: 'Complete',
                        name: 'complete[20]',
                        inputValue: '1'
                    },
                    {
                        boxLabel: 'Incomplete',
                        name: 'complete[20]',
                        inputValue: '2'
                    }

                ]
            }, {
                xtype: 'radiogroup',
                vertical: false,
                fieldLabel: ' ',
                labelSeparator: ' ',
                reference: 'radiofield',
                val: 2,
                items: [
                    {
                        boxLabel: 'Complete',
                        name: 'complete[19]',
                        inputValue: '1'
                    },
                    {
                        boxLabel: 'Incomplete',
                        name: 'complete[19]',
                        inputValue: '2'
                    }

                ]
            },

在Load方法中，我像这样设置这些值

Ext.each(ids, function(id){
        var g = mainPanel.down('radiogroup[val='+id+']');
        var name = 'complete['+id+']';
        g.setValue({name: 2});//the value can be either 1 or 2
    });

如何设置radiogroup的值?请注意，当我给它们硬编码值时，如下所示

g.setValue({'complete[19]': 2});

它可以工作，任何解决方案
