1 var radios = Ext.create('Ext.form.Panel', {
2 title: 'RadioGroup Example',
3 300,
4 height: 125,
5 bodyPadding: 10,
6 renderTo: Ext.getBody(),
7 items:[{
8 xtype: 'radiogroup',
9 fieldLabel: 'Two Columns',
10 // Arrange radio buttons into two columns, distributed vertically
11 columns: 2,
12 vertical: true,
13 items: [
14 { boxLabel: 'Item 1', name: 'rb', inputValue: '1' },
15 { boxLabel: 'Item 2', name: 'rb', inputValue: '2', checked: true},
16 { boxLabel: 'Item 3', name: 'rb', inputValue: '3' },
17 { boxLabel: 'Item 4', name: 'rb', inputValue: '4' },
18 { boxLabel: 'Item 5', name: 'rb', inputValue: '5' },
19 { boxLabel: 'Item 6', name: 'rb', inputValue: '6' }
20 ]
21 }]
22 });
里面有设置项,把checked设为true,拿值的话用
var val = radios.down('radiogroup').getValue()['rb'];
