java 如何用J radiobutton 做一个有ABCD选项的button组，然后获取选定的选项是哪个。

Answer 1

//声名两单选按钮
private JRadioButton male;
private JRadioButton female;
//初始化按钮男默认选
male = new JRadioButton("男", true);
female = new JRadioButton("女");
//两按钮放同组
ButtonGroup group = new ButtonGroup();
group.add(male);
group.add(female);
//actionPerformed(...)获得按钮选择值
DefaultButtonModel model = (DefaultButtonModel) male.getModel();
if (model.getGroup().isSelected(model))
//男被选处理

else
//女被选处理

Answer 2

js这样写
flag=true;
var a1=false;
for (i=0;i<document.basic.info1.length;i++)
{a1=a1||document.basic.info1[i].checked;}
if (a1==false){alert('Please choose Work location！');
document.basic.info1[0].focus();
return a1};
asp这样写
info1=trim(request.form("info1"))

因为radio按钮每组只有一个checked状态，name每组应该一样，获取的应该是value或者是txt的值，看看c#radio的用法吧
