js下获得单选框的值的代码_表单特效

<script language="javascript" type="text/javascript"> function get_radio_value(field){ if (field && field.length){ for (var i = 0; i < field.length; i++){ if (field[i].checked){ alert(field[i].value); } } }else{ return; } } </script> <form name="myForm"> <div> <input name="point" type="radio" value="是" checked>是</div> <div> <input name="point" type="radio" value="否">否</div> <input type="button" value="确定" onclick="get_radio_value(myForm.point);"> </form>
[Ctrl+A 全选 注:如需引入外部Js需刷新才能执行]
