JAVASCRIPT引用INPUT值问题
有两组INPUT值，A01，A02，如下<input name="A01"value="FD"type="radio">
<input name="A01"value="ERERER"type="radio">
<input name="A01"value="HGHGHGH"type="radio">
<input name="A02"value="FD"type="radio">
<input name="A02"value="ERERER"type="radio">
<input name="A02"value="HGHGHGH"type="radio">
两组值中有一个属性为CHECKED， 就返回TRUE，否则返回FALSE
用JAVASCRIPT怎么写呢？
